No kidding. It doesn’t isolate what part of the vehicle its coming from. Not front or back or which side. Total waste of time and money. **Developer response:** Dear App Reviewer33, Thank you for your feedback. I’m sorry the app did not meet your expectations. The app is designed to help identify and isolate the source of vibrations. This feature is described in the user manual, including how to perform measurements from different positions in the vehicle to narrow down whether the vibration originates from the front or rear side. If you only received a general vibration indication, it is possible that the measurement procedure was not followed as described in the manual. If you contact us through the support option in the app, we’d be happy to help you determine the source of the vibration. Thank you for giving the app a try. Let us know if you’d like a full refund! ### 1/5 — No Staggered Wheel input or mention *2024-02-29* The app does not recognize staggered wheel setups, mention in notes, or have a way to contact for asking. **Developer response:** Please enter either the front size or the rear size, as the total diameter should be the same. You can always contact us at info@doao-consulting.se! ### 1/5 — Nice idea, but ... *2019-03-09* This app graphs the car's vibrations. However, going from the graph to a diagnosis would be the useful step that is missing in this app. You feel the shimmy, the graph shows the shimmy, good. Is the shimmy due to poor balancing or poor alignment and of which tire? Is the problem critical or acceptable? What should you do about it? In my experience the app is not ready for prime time. Should you pay 18 bucks to encourage the developer to work on a useful version? If you feel like a generous sponsor, do it. **Developer response:** Hello JC-Berkely, I'm so sorry to hear that you are disappointed with the app. You must have gotten the old version of the HelpBook. Please view the HelpBook once more in your app. 1. The accepted level is stated in the HelpBook, it's 12mG. 2. The red boxes would be the app identifying your vibration problem. 3. After running the Diagnose, go to the HelpBook, and read about the vibration type that is causing your issue. I really want the app to function for you, so please contact me with the issues and I'm happy to do what it takes to work these issues out! I will also be happy to provide a full refund. ### 5/5 — Vey helpful! *2021-01-16* Very nice app and easy to use. Just found that it can be on CVT’s. ### 5/5 — Vibration or Shimmy in your car this app is for you! *2020-02-03* If you have ever had car with unexplained or undiagnosed shimmy or vibration this app will probably solve it for you. From basic wheel out of true all the way through to complex primary balance engine issues. I had an issue when I moved to IPhone XS Max and dark mode and thought I had lost one of my “go to” workshop tools. A note to the developer and it is all fixed so I’m back in business. An excellent tool at a small price! **Developer response:** Hello Mark! Thank you for pointing out the issue with version 1.0.19. This is now fixed in version 1.0.21! Happy to hear that you had great success using the app for diagnosing your issues! ### 5/5 — Nice 👍🏻 *2019-10-01* This tool is an inexpensive was to really visualize vibrations that occur in a vehicle. It's easy to use and very handy for isolation vibrations. You don't have to enter more information than the tire sizes, and this saves you a lot of time, especially under a tight dealership schedule... ### 5/5 — Powerful tool *2019-07-27* It takes a while to understand the concept, but once you do this is a very powerful tool! ### 5/5 — Works well *2019-07-26* This app, and the support, helped me conclude that the highway vibration I was experiencing was due to my large diameter rims and old tires. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
