Does not seem applicable to small engins (which was part of my Play Store search criteria).

Measurment is depend on devices capabilities. Maybe mail us your problem and see if it's applicable or not?

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.

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
