I have an nvh app, in my job it is insanely useful. Previously I had spent customers money and my time balancing shafts and wasting time (very unfortunate) these apps have saved me so much time and money. Fun tip: I've noticed it's very common for tires to shake, regardless or brand or wear. Always watch the wheel/tire on the balancer to visually see it is true, if it's not you will have to measure the out of round. Sometimes a out of round tire and rim can be matched low rim spot to high tire spot, I've had this work many times. This app was used on my 1970 c20, and detected a severely out of balance driveshaft, ironically after I had installed used tires, the driveshaft lost a weld on weight, sent the shaft out thinking it was still tires and sure enough, smooth as silk. Sometimes cars can be tricky, this app helps!
That's really great how the app tells you if its a first order or second order vibration. My butt cant decipher a first or second order vibration unfortunately. Throughout the drive however it may produce a vibration on multiple occasions of various amplitudes. Imagine the pain involved in swapping out a ujoint that is assumed to be the problem when it actually needs balanced. Very Cool!
Fantastic app. I bought it for $99 and that’s definitely worth it at that price. Having mechanics guess what might be wrong and replacing unnecessary parts quickly makes this app very worthwhile.
Met John and his son at a allison transmission function recently and talked to a few of the engineers for allison that are using this app all thing were positive about the app - the cost of the app. I am currently working on and trying to get my shop to purchase the app and a iPad for shop to put it on for the shop to use. From what the allison transmission engineers have said it will be very useful tool. Hope to have it in our shop soon.. and John like watching your videos on here.
John another super good job with this APP. I've recently seen a demo of the software. It is excellent. Anyone that works with NVH should have it. A bit pricey, but it will pay for itself, in a very short time.
This is a cool app that you've co-created and the demonstrations have been excellent thus far. I'm no automotive technician but your in depth videos have definitely helped me to understand various issues with my vehicles. It's also interesting to watch you drive around Ogden, it's not often that I watch TH-cam videos from my hometown area. Please keep making TH-cam content!!
Love the idea of this app , to diagnosis my Audi Quattro and it’s many driveline related shudders . But the reality is I can replace 3 cv shafts for the price of this app and that’s about 50% of the possible issues of the vibration . Wheel Bearings and ball joints pretty easy to diagnose. Tricky stuff is “out of round” rims or small drive line imbalance
I have a 2018 silverado 1500 with the Chevy shake. Brand new out of the box and all these headaches. I will gladly spend the 400.00 without a thought because the past 5 weeks has been hell on me and 4 trips to the dealer, ( and I live a long ways away from the dealer) and all the time it takes, would have paid for it by now!!! You do amazing and informative videos, have been learning so much. Love the detail when you describe things the way you do. Please keep them coming!!
Another good demo, to bad I have a android phone. I would have a good test subject to test it on. A Audi A3 TDI with a 50-60 mph shake when going up a hill. I'm suspecting the Dual mass flywheel. But it would be cool to see if this tool would pick it up. Keep up your work! Thanks!

I guess: App has signal characteristics of axles. Smart phones have acceleration sensor on its own. You give app prior knowledges about axles and phone records vibration signals. In conclusion app matches prior information and vibration signal. And it makes a prediction. This is my estimation.
Thank you! After removing the additional wheel weights, the vibration frequency stayed the same (as it should), but the amplitude dropped almost to zero. Best wishes!
I have a question regarding how to manually set up my specific vehicle. It is a medium duty, 6x6 former military vehicle that I’m working finding the cause of a vibration. I assume that I would have to manually enter all the information which is fine, all of that information is available. The vehicle has 2:1 geared hubs and has an effective R&P ratio of 7.80 because of it. Do you recommend setting the axle ratio at the 3.90 with a tire rolling diameter of half the actual diameter or 7.80 with the full rolling diameter? …or would you recommend something completely different? Thanks for your time
Will it diagnose rear end or transfer case vibrations too? I've got a 2005 Dodge 2500 quad cab 4x4 diesel that I bought in 2007 that was hit in the right front hard enough to twist the front axle. I replaced it when I rebuilt the truck and have ran it 80K miles since but have always noticed a harmonics vibration at road speed. When self diagnosing it, I removed the wheels and ran it on my lift, still had it. I removed the front drive shaft, still had it. I removed the rear driveshaft and it ran smooth. I had the rear driveshaft balanced twice and even install another driveshaft & still vibrated. They took the weight off the front of the driveshaft and it helped but I could still feel it. I also wonder if its a bearing in the rearend. Now this month, a new buzzing vibration started under load at all speeds but hardly noticeable when decelerating. It's May 2018, is there a better analyzer now to find the problems my truck has?

Hi, some mechanics mark the output flange of the differential and transmission when removing a drive shaft. Is that really necessary ? The front and rear drive shaft are balanced together , but the transmission and differential position doesn't matter right?
Did you get any answer regarding this? I am fighting a driveline vibration. I have tried multiple things. Somebody asked in a forum if I had taken the flanges out of phase. I am assuming this is very similar to what you ask. I cannot even remember if I moved them, but for sure I didn't verify, nor marked anything (since I thought the only thing needing a balancing was the driveshaft
@@le0nida525 I didn't get an answer for sure. But i'm pretty certain that the output flange position of the transmission and differential doesn't matter... I forgot to mark output flanges properly and I got no vibrations after servicing my drive shaft. (it doesn't hurt to mark them if you can though)
@@farerse Thanks for your reply. I appreciate it. Well, I was sort of hoping it may matter. I have replaced my driveshaft twice, replaced the leafsrpings, no luck yet
@@farerse Thanks, no problem. I still have a few ideas to try. The shop where I am buying the driveshaft is helping a lot as well. It's a tacoma v6. There's plenty of help when the vibes are caused only by the driveshaft or the angle of the axle. But nothing else (that I know). I am trying also to get a shop that do Vibration analysis. This app here seems expensive but I am still considering an option if all else fails.
I was all set to get this app as I have a "wobble" in the car that so far ball joint and wheel bearing have not fixed, latest suspect is a subframe joint, but at £100 UK thats a bit steep to see if it works, I see there is a £23 one also but it doesn't really show much on the functionality and again not willing to spend £25 to see if its useful
Thanks for your feedback. £100 UK is a great price for what the app does. That is the sales price, it is normally £400 UK. You could easily spend more than throwing parts at your car trying to fix it. With the app you can skip the guessing, diagnose it properly and see what it really needs. Best wishes.
Did the installation of such hose clamp which produced a reading for first order driveshaft vibration in the app create a perceivable sudder in the seat inside the car?
price is a bit of a barrier. I'm sure the math and logic are excellent but is smart phone on dash a good sensing tool. I would have thought it should be securely mounted. what about device bouncing vibration?
Thanks for your feedback. The price is low compared to guessing and buying parts and services you do not need. This app not only tells you the source of your vibration, it eliminates the rest of the parts on the vehicle as possible sources. Every rotating part on the vehicle has a unique signature. The device ignores anything that is not a possible part on the car. This means that bouncing, cracks in the road, etc, will have no affect on the diagnostics. Securely mounting the device is not necessary, although it is preferred. The only difference between securely mounted and not securely mounted is the amplitude level of the vibrations detected. The frequencies of the vibrations are the same either way. It is all relative anyway. The frequency with the highest average amplitude is probably the vibration you are feeling as you drive the vehicle. I hope that helps. Have a good day.
hi weber auto, i really need your help. i have 1998 toyota 4runner 4 cylinder manual. after i replace the drive shaft and the drum brake. its start have death wobble(its come and go at the highway speed) i brought it to several mechanic( even a suspension specialist) but they cant figure out the problem is. when its has a death wobble the brake wont engage properly(i need to pull over to complete stop to stop the death wobble before i can drive again) do u think is the drive shaft? please help! thank you
If there was no death wobble before you replaced the driveshaft and the brake drum, then the driveshaft and the brake drum is responsible. I do not think the driveshaft would cause that, but a brake drum could. Perhaps the brake drum is out of round or not mounted properly, or defective. Best wishes!
weber auto, thank you! but i think is my driveshaft because it only happen at highway speed and i found out today when i step on the gas pedal and lets it go is start to have vibration.
If you have a vibration that you can't find, check the driveshaft! I have seen them bent, out of balance, or having bad u-joints that all cause dashboard shaking vibrations... People always suspect tires or wheel bearings--I don't know why.
Just had a 4 inch lift and having a hell of a time figuring out my vibration. Added $800 more cause mechanic said sye would fix and still vibration. I hit the clutch and most goes away in neutral. I'm guessing pilot bearing. @30mph seams to start to fill it everywhere and @ 55 OMG and if you feather the gas just right it will shake your teeth out. If I had the $400 I'd fire my mechanic and hire a labor to fix my stuff.
Hi, it is $399 for the app. That is a bargain compared to the $3000 cost of our closest competitor. I know that is still a lot of money, but you will pay more than that just guessing. $80 tire balancing just for starters. Best wishes
@@WeberAuto I have to disagree. I have a 4X4 and if I DIY, I can replace all U-joints, tire balancing (which doesn't cost $80 by the way) and a drive shaft balance for about less than half that.
Hi, thanks for the feedback. in my 22 years of performing vibration diagnosis I have learned that almost all vehicle vibrations fall into one of three groups of rotating parts. 1. Tire speed related vibrations. 2. Driveshaft speed related vibrations. 3. Engine speed related vibrations. There are other very rare, but possible conditions as well. Determining which of these groups/conditions your vibration falls into has been very difficult until now. The NVH App will show you and tell you which of these groups the vibration on your vehicle fits into. Each of the previous three groups has many possible conditions/malfunctions/mis-adjustments that can make the rotating parts cause a vibration. The diagnostic procedures and repair procedures for each of these conditions are included in the NVH app as well as dozens of training videos. I will be making additional videos in the future on these topics.
Would have bought, but would rather take to a mechanic for $400... At that rate, that's over 3 hours of their diagnosis time. Would rather go that route than an app...
nice looking software. I like the idea you and the students created it The cost is a bit much for some of us. Do you think you would have a 10 day trial for a lower price.
Obviously the common theme here is the incredibly high price for an app that only narrows the problem down to a large very very general area of the vehicle.
Right. For 400 dollars you can change out all of you tie rods(inner and outer) control arms, u joints and probably cv axles using rock auto. Bam problem solved. Unless it’s your tires which would be obvious.
The app really needs a remote magnetic wired or bluetooth accelerometer probe to narrow down the source of the vibration (ex which motor mount, which U Joint, which tire). As it is, you have to spend hundreds and hundreds or thousands of dollars on disassembling parts to determine the specific part that is bad.
Hi, the NVH app does not need anything besides your phone and its internal sensors. There is an optional bluetooth adapter for engine speed related vibrations, but they can be diagnosed without it. The bluetooth adapter just makes it faster to diagnose. Yes, it will work on your Nissan truck or any other truck or car. I hope that helps. Thanks for watching.
Some may say expensive, but then again mechanics should be able to solve issues without part trial and era. 5 mechanics in my area and none of them told me the same thing or correct thing that was wrong with my ride.
hi, my car shakes and I feel like two pieces are rubbing, only happen when accelerate and after a while, so if I start the car and drive nothing happen but after a while like 10 minutes starts shaking, it get worse when climbing a hill, if I park and rest for a while the shakes dissapears.
Hi, it uses the iPhone's internal sensors to detect vehicle speed and vibrations. It can estimate engine rpm, but there is an optional bluetooth adapter to read engine rpm directly.
If I could tell you that, I would not need the app. There are several things that can cause a vibration to occur at one rpm range. You can guess and spend a lot of money replacing parts, or you can buy the app and find out what is causing it. Best wishes
WeberAuto Thanks, my drivetrain has a high frequency vibration starting at 30 mph , I changed the rear drive axles but the vibration is still there. I can feel the vibration in the seat and the dashboard is also vibrating. Would the app show if a wheel bearing is bad? thanks
+Greg Blank Thank you! Prior to this App coming out, the least expensive vibration analyzer you could buy was in the $2600-$3000 price range. This NVH app on the Apple App store is expensive at $399, but well worth the expense if you are involved in vibration diagnosis. An Android version will be released later this summer. Thanks for watching!
This looks like a great app but gotta be honest with you, it's way too expensive for most people. I'm showing $399 for the app. Why is it so expensive?
only way the phone could separate vibrations is by the speed of the vibration. this will not be accurate...at the price it should come with a jar of vasoline..
as funny as this is^^ @ 0:18 he claims to have the vehicle set up with "vibration installed on it"; maybe he means wireless sensors around the vehicle connected to his phone. I couldn't see this app working any other way (imagine slapping your phone on the dash on a gravel road. It would probably say the entire truck is fucked haha.) He could have gone more in-depth on how it works but it seems like a good tool for preventative maintenance.
@@dangerdavefreestyle the problem i have with that is, theres a KNOWN driveshaft out of balance and it still picked tire vibration as the main issue. How do you accurately use this app and sell a fix the first time correctly? Did this truck already have a known vibration before rigging the DS?
@@95GTSpeedDemon i get what youre saying, perhaps it has false positives or is picking up erroneous noise or it flat out needs improvement. -------- What if you could select the glowing red or graphed vibration being shown and listen to it with a pair of earphones. If it is creating a resonant frequency and the device picks that up real time it should be able to replicate it as well as a chassis ear that alligator clamps a transmitter device youd listen to with earphones.
I have an older truck, so i dont doubt it will pick up some erroneous vibrations, thing is, my chief complaint of a drivetrain vibration is quite audible inside the vehicle, and i'll be pleased to see the info of something like "vibration occured 1,557 times with an amplitude off the charts." and where and what order etc....
The app has just over 500 downloads in how many years? Sell 1 app 1000000 times for $1, or try to sell 1 download for $1000000? If I put the time into the development, I'd do the 1000000 downloads for $1 and retire next week. Too bad I'm too dumb to create such an app. I'll have to keep working for a living.
I'm in Australia and saw you at 7minutes at over 70mph look at your phone for ages and was horrified until I realised your car is left hand drive. Ours are right hand🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
We get that question all of the time. This is not just some flashlight app that took 3 days to write, this app will tell you what is causing the vibration on your vehicle and show you how to repair it. It took over a year to write and includes 27 years of accumulated knowledge and experience from an automotive vibration expert. Best wishes!
That is true, there are a lot of great mechanics out there. There are also a lot of mechanics that have no idea of what to do if balancing your tires does not fix the problem, so they will start guessing and wasting your money. (By the way. balancing tires will cost you at least $48). We have identified nearly 300 possible causes of vibrations of a typical vehicle. Out of balance tires isn't even the number one cause of vibrations, it is number two. The number one cause is time consuming and difficult to do, so it rarely gets checked.
Ranger Danger, This is the cheapest Automotive product that I've seen in decades. To give you an idea of what may be considered expensive , look @ what it cost to purchase the Noise Vibration Analyzers plus the 4-Channel Pico Scope (required) at www.picoauto.com ....After that , look at what things cost @ one of my other favorite site called www.automotivetestsolutions.com The Weber State University Automotive Instructor is offering you something 95 % cheaper than the Pico Scope + Pico NVH software combined & required to operate. You won't see anything as good as this from Automotive in 25 more years. Automotive Industry requires more money than any other Trade or Profession to work on todays vehicles. Even a person that doesn't work on cars can be a "Star" when they take it to a Shop & they might not be able to figure it out...( The Shop or Dealership ).You're be knowing more than the Mechanic on this Subject. Hope this helps & sheds a little light. "Hop-A-Long" Barkwell Southern California
@@WeberAuto I would like to know how well it can pinpoint problems. I was in an accident and cannot discern where exactly a vibration I have is coming from. The mechanics replaced the wheel hub bearing, and that took care of one source. I don't know if that one came back or now I have another one, my initial guess being the transmission. (fought to get that covered by my insurance) but now I'm more inclined to think it's something else, though a local dealer says it is the transmission. I would like to be able to definitively say without taking the transmission apart. I strongly suspect now that there is some other source like the cv axle. Just how microcosmic can it get? I'm really in a pinch - I do not want to swap the transmission out with a used one, and don't know anyone I really trust. this could be just the answer I needThanks.
Steep price for an app, I appreciate the work its a great tool. However for those money as DiY mechanic would probably use it once only to find the issue which makes it expensive.
WeberAuto I agree with you, but with a price of 250 $ a lot of enthusiasts will buy it and the profit will be much higher. At current price only the professional workshops can afford to buy it. It's just a suggestion :)
I agree with Merp. $10 for a nice app like this may seem too cheap but you'd make up for it in quantity (especially since your marginal cost is $0). Make it cheap and add a forum type feature for people to say how they fixed different vibrations.
WeberAuto Ya, but I can’t justify the expense! That’s a little gougy imho. I figured it would be expensive but $550? That’s more than I make during a good week and rent is $1100/mo. That’s just a lot of cash.
Asking to much for app, could be worth it for a mechanic or a shop. But not worth it for the every day user, when they can pay an 1/8 of the price to have a mechanic diagnose the problem.
There are almost 300 possible causes of vibrations on today's vehicles. Many mechanics don't know what to do if a tire balance does not fix the problem. The NVH app is expensive, but it is accurate and eliminates guesswork and wasted money spent on un-needed parts or repairs. the NVH app is on sale for 50% off this month. Best wishes!

Yea for $400 dollars lol ,,, if your a shop maybe worth it if it actually helps ya fix it with the correct diagnosis . Otherwise def not worth it as a individual.
1st order Driveshaft vibrations are only caused something rotating the same speed as the driveshaft that is out-of round or out-of-balance. The NVH app detects the vibration regardless of the cause. It is up to the repair technician to use the built-in help file instructions to determine which one it is. Thanks for your feedback.
Wow that's pretty nice but way to pricey. Out of balance drive shaft isn't hard to diagnose nor a bad ujoint... If your clueless and good mechanic gives free estimates. The sensors on most phones suck. Thank you for trying but it's definitely too high.
Why don't you see what the NVH kit plus the Pico Scope ( 4 Channel or 2 Channel Scope ) cost from a Top Shelf Corporation charge from www.picoauto.com......look at what things cost @ www.automotivetestsolutions.com cost, which I adore. After these "2" visits , "Too High" won't even roll off your lips. Hope this helps and let you see what things really cost.

@@farerse Thanks for your reply. I appreciate it. Well, I was sort of hoping it may matter. I have replaced my driveshaft twice, replaced the leafsrpings, no luck yet
@@le0nida525 wish I could help .. what make is the vehicle anyway? Sounds like a truck .. maybe others will know
@@farerse Thanks, no problem. I still have a few ideas to try. The shop where I am buying the driveshaft is helping a lot as well. It's a tacoma v6. There's plenty of help when the vibes are caused only by the driveshaft or the angle of the axle. But nothing else (that I know). I am trying also to get a shop that do Vibration analysis. This app here seems expensive but I am still considering an option if all else fails.
I was all set to get this app as I have a "wobble" in the car that so far ball joint and wheel bearing have not fixed, latest suspect is a subframe joint, but at £100 UK thats a bit steep to see if it works, I see there is a £23 one also but it doesn't really show much on the functionality and again not willing to spend £25 to see if its useful
Thanks for your feedback. £100 UK is a great price for what the app does. That is the sales price, it is normally £400 UK. You could easily spend more than throwing parts at your car trying to fix it. With the app you can skip the guessing, diagnose it properly and see what it really needs. Best wishes.
Did the installation of such hose clamp which produced a reading for first order driveshaft vibration in the app create a perceivable sudder in the seat inside the car?
Great video, great channel. Extremely informative
Thank you!
what are you smoking?
Does this require any sensors or just drive with it on?
price is a bit of a barrier. I'm sure the math and logic are excellent but is smart phone on dash a good sensing tool. I would have thought it should be securely mounted. what about device bouncing vibration?
Thanks for your feedback. The price is low compared to guessing and buying parts and services you do not need. This app not only tells you the source of your vibration, it eliminates the rest of the parts on the vehicle as possible sources. Every rotating part on the vehicle has a unique signature. The device ignores anything that is not a possible part on the car. This means that bouncing, cracks in the road, etc, will have no affect on the diagnostics. Securely mounting the device is not necessary, although it is preferred. The only difference between securely mounted and not securely mounted is the amplitude level of the vibrations detected. The frequencies of the vibrations are the same either way. It is all relative anyway. The frequency with the highest average amplitude is probably the vibration you are feeling as you drive the vehicle. I hope that helps. Have a good day.
Hey John, very nice app! Congratulations!
Just for my understanding, which Iphone sensors are used to collect vibration data: mic, g-sensors or other?
Thanks! 3-axis accelerometer and 3-axis gyrometer
Cool! What are the frequency limits of those sensors?
It depends upon the device, but 100Hz typically
and a vasoline sensor with its price.
hi weber auto, i really need your help. i have 1998 toyota 4runner 4 cylinder manual. after i replace the drive shaft and the drum brake. its start have death wobble(its come and go at the highway speed) i brought it to several mechanic( even a suspension specialist) but they cant figure out the problem is. when its has a death wobble the brake wont engage properly(i need to pull over to complete stop to stop the death wobble before i can drive again) do u think is the drive shaft? please help! thank you
If there was no death wobble before you replaced the driveshaft and the brake drum, then the driveshaft and the brake drum is responsible. I do not think the driveshaft would cause that, but a brake drum could. Perhaps the brake drum is out of round or not mounted properly, or defective. Best wishes!
weber auto, thank you! but i think is my driveshaft because it only happen at highway speed and i found out today when i step on the gas pedal and lets it go is start to have vibration.
If you have a vibration that you can't find, check the driveshaft! I have seen them bent, out of balance, or having bad u-joints that all cause dashboard shaking vibrations... People always suspect tires or wheel bearings--I don't know why.
Thanks for your feedback
Just had a 4 inch lift and having a hell of a time figuring out my vibration. Added $800 more cause mechanic said sye would fix and still vibration. I hit the clutch and most goes away in neutral. I'm guessing pilot bearing. @30mph seams to start to fill it everywhere and @ 55 OMG and if you feather the gas just right it will shake your teeth out. If I had the $400 I'd fire my mechanic and hire a labor to fix my stuff.
Thanks for your feedback!
My 2 door tahoe is doing the same exact thing.
Could I use this on my military surplus truck?
Yes, you will need to enter your vehicle information (gear ratios), but it will work. Best wishes!
This app looks handy, but I don't think I can justify paying $549.99 for it... Any chance you have a sale planned?
Hi, it is $399 for the app. That is a bargain compared to the $3000 cost of our closest competitor. I know that is still a lot of money, but you will pay more than that just guessing. $80 tire balancing just for starters. Best wishes
@@WeberAuto I have to disagree. I have a 4X4 and if I DIY, I can replace all U-joints, tire balancing (which doesn't cost $80 by the way) and a drive shaft balance for about less than half that.
What camera and mount are you using to film under the vehicle while driving ...
Go Pro camera and mounting
again cool , also can you make a video how to solve the vibrations that should not be there in each section
Hi, thanks for the feedback. in my 22 years of performing vibration diagnosis I have learned that almost all vehicle vibrations fall into one of three groups of rotating parts. 1. Tire speed related vibrations. 2. Driveshaft speed related vibrations. 3. Engine speed related vibrations. There are other very rare, but possible conditions as well. Determining which of these groups/conditions your vibration falls into has been very difficult until now. The NVH App will show you and tell you which of these groups the vibration on your vehicle fits into. Each of the previous three groups has many possible conditions/malfunctions/mis-adjustments that can make the rotating parts cause a vibration. The diagnostic procedures and repair procedures for each of these conditions are included in the NVH app as well as dozens of training videos. I will be making additional videos in the future on these topics.
Will it work on a loud truck with mud tires??
Would have bought, but would rather take to a mechanic for $400... At that rate, that's over 3 hours of their diagnosis time. Would rather go that route than an app...
Understandable. Keep us in mind if you still have a vibration afterwards.
Absolutely not charging an arm and a leg for an app lol
wow, what a useful app! amazing.
nice looking software. I like the idea you and the students created it The cost is a bit much for some of us. Do you think you would have a 10 day trial for a lower price.
Thank you! No, this is already the least expensive option on the market. Many people spend more money guessing and buying unneeded parts.
Great video sir... thank you
Hey John. do you have any expected date at this time for the Android APP?
Cheers.
Hi, not yet. I will post it here on this channel and the NVH app Facebook page when it is #NVHApp
Obviously the common theme here is the incredibly high price for an app that only narrows the problem down to a large very very general area of the vehicle.
Right. For 400 dollars you can change out all of you tie rods(inner and outer) control arms, u joints and probably cv axles using rock auto. Bam problem solved. Unless it’s your tires which would be obvious.
Are there going to be updates to this app? What do you think updates will cost? Thanks!
the phone's shaking in his hand,can't be the ideal method if use ,would it not be better to sit on the floor or drive line tunnel?
When will the Android App be available? Summer 2017 is almost over
It will be available by the end of this month! Thank you!
The Android Version will be available August 31, 2017. vibratesoftware.com/buy-the-nvh-for-android-app/
Does this App have capability for metric data input/output?
Yes, you can select the units in the app settings
The app really needs a remote magnetic wired or bluetooth accelerometer probe to narrow down the source of the vibration (ex which motor mount, which U Joint, which tire). As it is, you have to spend hundreds and hundreds or thousands of dollars on disassembling parts to determine the specific part that is bad.
Cool app! I still dont understand how does it works. Bluetooth? May i use it on my 2010 nissan truck?
Hi, the NVH app does not need anything besides your phone and its internal sensors. There is an optional bluetooth adapter for engine speed related vibrations, but they can be diagnosed without it. The bluetooth adapter just makes it faster to diagnose. Yes, it will work on your Nissan truck or any other truck or car. I hope that helps. Thanks for watching.
This app now on android for Australian $540. You good ?? This's just a app
is it possible to share the manual of this product looks interesting...!
No, it is part of the app. Have a good day!
good one, thanks ...
Thank you!
Some may say expensive, but then again mechanics should be able to solve issues without part trial and era. 5 mechanics in my area and none of them told me the same thing or correct thing that was wrong with my ride.
Thanks for your feedback!
Is there a free trial on this app?
Would this work on a modified 2010 Camaro with a considerably loud exhaust?
Yes, no problem.
hi, my car shakes and I feel like two pieces are rubbing, only happen when accelerate and after a while, so if I start the car and drive nothing happen but after a while like 10 minutes starts shaking, it get worse when climbing a hill, if I park and rest for a while the shakes dissapears.
Check for axial (up and down) end play in the slip joints of the driveshaft
How does this detect the issues? Do you have the phone connected to anything?.
Hi, it uses the iPhone's internal sensors to detect vehicle speed and vibrations. It can estimate engine rpm, but there is an optional bluetooth adapter to read engine rpm directly.
I have a 1996 Jeep Grand Cherokee Laredo that starts to vibrate around 1500 rpms but stops at a higher rpm or lower what is my problem
If I could tell you that, I would not need the app. There are several things that can cause a vibration to occur at one rpm range. You can guess and spend a lot of money replacing parts, or you can buy the app and find out what is causing it. Best wishes
Is there any difference between android and ios app? I am considering the android app because is cheaper
no difference, they are the same price as well. Thank you!
WeberAuto Thanks, my drivetrain has a high frequency vibration starting at 30 mph , I changed the rear drive axles but the vibration is still there. I can feel the vibration in the seat and the dashboard is also vibrating. Would the app show if a wheel bearing is bad? thanks
WeberAuto The Google play shows the app at 2500kr ( danish crowns) while the app store shows it at 3499 kr
That is interesting. they are supposed to be the same price of $399 USD. Thank you
WeberAuto Thank you, 399 $ is reasonable but 550 $ as it is now in the danish app store its too much. Maybe its an error
This is COOL. Is it super expensive?
+Greg Blank Thank you! Prior to this App coming out, the least expensive vibration analyzer you could buy was in the $2600-$3000 price range. This NVH app on the Apple App store is expensive at $399, but well worth the expense if you are involved in vibration diagnosis. An Android version will be released later this summer. Thanks for watching!
Hello Wildcats, this is Weber Cooks
Hi there. Thanks for the visit
This looks like a great app but gotta be honest with you, it's way too expensive for most people. I'm showing $399 for the app. Why is it so expensive?
it is now $99
only way the phone could separate vibrations is by the speed of the vibration. this will not be accurate...at the price it should come with a jar of vasoline..
as funny as this is^^ @ 0:18 he claims to have the vehicle set up with "vibration installed on it"; maybe he means wireless sensors around the vehicle connected to his phone. I couldn't see this app working any other way (imagine slapping your phone on the dash on a gravel road. It would probably say the entire truck is fucked haha.) He could have gone more in-depth on how it works but it seems like a good tool for preventative maintenance.
after reading more of these comments fro weber auto I think the vibration is solely detected from the phone. If that's the case get the vasoline
Joel Gerrer I think he meant that he created a driveshaft vibration for the sake of the demonstration.
Ó
What does 1st, 2nd and 3rd order mean?
Order is the number of times there is a vibration on one revolution of a tire or driveshaft, etc.
Is this app good for semi trucks
The back of my truck jumps while I reach 45 mph and 70 mph. Could this be the reason?
It is possible, but without the vibration frequencies we are just guessing.
I think tires. Out of balance tires act up at 45 and again at 70 is what I been told. But I'm not 100%
Was the app correct? What was wrong with the truck?
Driveshaft
Is Audi Rs4 b5 2000-2002 in the library?
How much does this cost?
Is the app able to compensate for regular road vibration? Like when it's a concrete road and has all those expansion joints.
Yes, the app knows what to look for and ignores everything else.
What kills me is that you created a driveshaft vibration but the app picks up a tire vibration...
the app picked up both. however it favored the t3 due to high amplitude and number of repetitions. id bet that vehicle has some tire or wheel problem.
@@dangerdavefreestyle the problem i have with that is, theres a KNOWN driveshaft out of balance and it still picked tire vibration as the main issue. How do you accurately use this app and sell a fix the first time correctly?
Did this truck already have a known vibration before rigging the DS?
@@95GTSpeedDemon
i get what youre saying, perhaps it has false positives or is picking up erroneous noise or it flat out needs improvement.
--------
What if you could select the glowing red or graphed vibration being shown and listen to it with a pair of earphones. If it is creating a resonant frequency and the device picks that up real time it should be able to replicate it as well as a chassis ear that alligator clamps a transmitter device youd listen to with earphones.
I have an older truck, so i dont doubt it will pick up some erroneous vibrations, thing is, my chief complaint of a drivetrain vibration is quite audible inside the vehicle, and i'll be pleased to see the info of something like "vibration occured 1,557 times with an amplitude off the charts."
and where and what order etc....
Eyes on the road!!!
Thank you!
The app has just over 500 downloads in how many years?
Sell 1 app 1000000 times for $1, or try to sell 1 download for $1000000? If I put the time into the development, I'd do the 1000000 downloads for $1 and retire next week.
Too bad I'm too dumb to create such an app. I'll have to keep working for a living.
I'm in Australia and saw you at 7minutes at over 70mph look at your phone for ages and was horrified until I realised your car is left hand drive. Ours are right hand🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Lmfao!!!!
I wish it is a bit affordable. many would pick it up
it is now $99
300 dollars for this app your insane
As in "holy shit, that's cheap" or "holy shit, that's expensive"?
it must not work well or they would sell them cheap in large numbers. I don't see the speed of a vibration exterminating its location accurately.
...insanely cheap ! think of how much time....money you safe !!!
I couldn't locate this app in Google play for my Android. Bosche had their version
Ours will not be out until this summer, thanks.

Why is the app so expensive
We get that question all of the time. This is not just some flashlight app that took 3 days to write, this app will tell you what is causing the vibration on your vehicle and show you how to repair it. It took over a year to write and includes 27 years of accumulated knowledge and experience from an automotive vibration expert. Best wishes!
WeberAuto I understand that but It seems like a mechanic would charge the same price just to find out what’s causing vibration
That is true, there are a lot of great mechanics out there. There are also a lot of mechanics that have no idea of what to do if balancing your tires does not fix the problem, so they will start guessing and wasting your money. (By the way. balancing tires will cost you at least $48). We have identified nearly 300 possible causes of vibrations of a typical vehicle. Out of balance tires isn't even the number one cause of vibrations, it is number two. The number one cause is time consuming and difficult to do, so it rarely gets checked.
Ranger Danger,
This is the cheapest Automotive product that I've seen in decades.
To give you an idea of what may be considered expensive , look @ what it cost to purchase the Noise Vibration Analyzers plus the 4-Channel Pico Scope (required) at www.picoauto.com ....After that , look at what things cost @ one of my other favorite site called www.automotivetestsolutions.com
The Weber State University Automotive Instructor is offering you something 95 % cheaper than the Pico Scope + Pico NVH software combined & required to operate.
You won't see anything as good as this from Automotive in 25 more years.
Automotive Industry requires more money than any other Trade or Profession to work on todays vehicles.
Even a person that doesn't work on cars can be a "Star" when they take it to a Shop & they might not be able to figure it out...( The Shop or Dealership ).You're be knowing more than the Mechanic on this Subject.
Hope this helps & sheds a little light.

@@WeberAuto I would like to know how well it can pinpoint problems. I was in an accident and cannot discern where exactly a vibration I have is coming from. The mechanics replaced the wheel hub bearing, and that took care of one source. I don't know if that one came back or now I have another one, my initial guess being the transmission. (fought to get that covered by my insurance) but now I'm more inclined to think it's something else, though a local dealer says it is the transmission. I would like to be able to definitively say without taking the transmission apart. I strongly suspect now that there is some other source like the cv axle. Just how microcosmic can it get? I'm really in a pinch - I do not want to swap the transmission out with a used one, and don't know anyone I really trust. this could be just the answer I needThanks.
Steep price for an app, I appreciate the work its a great tool. However for those money as DiY mechanic would probably use it once only to find the issue which makes it expensive.
Thanks for your feedback. Guessing can cost a lot more than the app.
WeberAuto I agree with you, but with a price of 250 $ a lot of enthusiasts will buy it and the profit will be much higher. At current price only the professional workshops can afford to buy it.
It's just a suggestion :)
I'm just going to throw parts because at least I know in the end half my drivetrain will be new.
New trucks and cars are full of new parts and yet they still can have vibration problems. Thanks for your feedback
Price point is ridiculous. I can pay $50 for a mechanic to do a diagnostic why pay $399.99 for an app ?
LOL. So please tell me only one single mechanic who does this kind of diagnosis for $50!
Holy crap -- $400. Cool app, but I guess not for the DIY crowd.
Needs to be done on a dyno
Looks great but pricey for private people.
Wholly crap, $550.00 bucks ..... not practical for a single use consumer ....
Thanks for your feedback, guessing can cost a lot more than that.
But you would help more people and make your college a ton more money and fame if you sold it for 10 bucks.
I agree with Merp. $10 for a nice app like this may seem too cheap but you'd make up for it in quantity (especially since your marginal cost is $0). Make it cheap and add a forum type feature for people to say how they fixed different vibrations.
I wanted to buy it - it's 350 where I live. I can't spent that much for an APP. 100...maybe 150 would not be a problem but 350? Sorry but no.
WeberAuto
Ya, but I can’t justify the expense! That’s a little gougy imho. I figured it would be expensive but $550? That’s more than I make during a good week and rent is $1100/mo. That’s just a lot of cash.
You failed to mention the app cost $399.99 wow
This app would be great for a shop, but useless for the average DIY mechanic... 400$ for an app?!?!?! insanity.
this app looks good but its 600 AUD
Asking to much for app, could be worth it for a mechanic or a shop. But not worth it for the every day user, when they can pay an 1/8 of the price to have a mechanic diagnose the problem.
There are almost 300 possible causes of vibrations on today's vehicles. Many mechanics don't know what to do if a tire balance does not fix the problem. The NVH app is expensive, but it is accurate and eliminates guesswork and wasted money spent on un-needed parts or repairs. the NVH app is on sale for 50% off this month. Best wishes!
Sounds like your going to the wrong mechanics, might want to try a mechanic with more skill.
Oh well that's just graet 😢 road testing my vehicle .parts ordered .and someone pulls out in front of me 😲😲

$400 to fix your vibration. Does it really matter if it is an app?
WeberAuto $400 to diagnose the vibration.
Then parts, labor, etc.
Nope I'll pass, way more expensive than the driveshaft itself.
Did you actually check the price?
Yea for $400 dollars lol ,,, if your a shop maybe worth it if it actually helps ya fix it with the correct diagnosis . Otherwise def not worth it as a individual.
Yeah but you were simulating a driveshaft vibration with a counter weight. Duhhh
1st order Driveshaft vibrations are only caused something rotating the same speed as the driveshaft that is out-of round or out-of-balance. The NVH app detects the vibration regardless of the cause. It is up to the repair technician to use the built-in help file instructions to determine which one it is. Thanks for your feedback.
$600 bucks for app. 😝🤨
Wow that's pretty nice but way to pricey. Out of balance drive shaft isn't hard to diagnose nor a bad ujoint... If your clueless and good mechanic gives free estimates. The sensors on most phones suck. Thank you for trying but it's definitely too high.
