- Measure revolution per minute for any of rotaty device.

Features:
- Measure instant RPM value
- Calculate avarage RPM value
- Save results for motor calibration.

I am a hobbyist software developer as well electronic hobbyist. Sensoring RPM with a camera is possible but it surely don't need to run with a game engine (Unity). Make a proper app with code base, it gives more control and more possibilities than doing it with Unity.

Measures RPM OF YOUR PHONE, which it seems to do just fine. I suppose this is useful for certain scenarios, but none of those scenarios are mine. Not being useful in my particular case is not this app's fault though, and it seems most reviewers here don't understand this concept.

After disabling possibly 400 different cookies and Ad vendor options, I can confirm that the app does absolutely nothing. Don't bother wasting your time
