Does your vehicle have a vibration problem? NVH takes the guesswork out of diagnosing it! Just follow the road test instructions in the tutorial, and the NVH app can automatically detect the type of vibration your vehicle is experiencing. - There are 14 types of vibrations: - Tire speed-related (3 types) - Driveshaft speed-related (3 types) - Engine speed-related (7 types) - Electric Motor Speed Related (1 type) - Each type of vibration has unique causes. A vibration type is not the same thing as a vibration source. There are many possible causes (sources) for each vibration type. Just follow the app's diagnostic steps to identify the source of vibration. - There are almost 300 possible causes of vibration concerns in today's vehicles. - Tire speed-related (77 Possible Causes) - Driveshaft speed-related (123 Possible Causes) - Engine speed-related (76 Possible Causes) - Electric Motor Speed Related (Several Causes) More than "Just an App," this is a tool for professional service technicians and anyone with a vibration concern on their vehicle. KEY FEATURES: - QUICK, ACCURATE, AND PRECISE: The NVH App can be set up and ready to begin diagnosis in as little as 30 seconds! - VIBRATION DIAGNOSIS: Place or mount your device against a solid surface in your vehicle, and the internal sensors will measure and analyze your vehicle's vibration problem. - LIVE RESULTS: Watch one of three different displays that show you live measurements of your vibration in various ways to ensure you have all the information you need. - MULTI-PART ANALYSIS: - AUTOMATIC: Not sure how to interpret your results? NVH will analyze your road test for you and tell you which type of vibration problem your vehicle has. - TOTALS: Want to get into the numbers yourself? NVH shows you statistics for each type of vibration detected and breaks them down by vehicle speed to give you even more information. - PDF REPORT: print, email, or save a PDF diagnostic report showing all the analysis details. - RECORD: Record your road test and watch it again in real-time, or pause and go through it step by step. - SHARE: Want another field service engineer, mechanic, or friend to see your test and give their opinion? Export your recordings to an NVH file to import them into their device and view your recordings and their analyses. You can also print or send a PDF report detailing the recording analysis. - VEHICLE DATABASE: NVH has an extensive database of 45,184 vehicles to choose from, so that you can pick your vehicle and go!

This app is intended to assist users and professionals by providing additional data points for evaluation purposes. AcceloVibe does not interface with or access any vehicle systems. Limitations: AcceloVibe does not access vehicle systems. It offers supplementary information based on engine vibration data, not a definitive diagnostic. Always consult a professional mechanic for conclusive assessments. No Warranty: AcceloVibe is provided "as is" without warranties of any kind.
