Comments on Tachometer - RPM measuring for Android

★★★★☆ Dan Hessler · Feb 19, 2023
I had to tape my phone to a record for 78rpm, my phone kept flying off. So far it sounds in tune.
★★★★★ Richard R · Oct 11, 2025
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.
★☆☆☆☆ IskandarAlex2 · Apr 20, 2024
I am a hobbyist software developer as well electronic hobbyist. Censoring RPM with a camera is possible, but it surely doesn'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.
★☆☆☆☆ Suraj Parihar · Aug 2, 2023
Not real tachometer in the app. Not useful.
★☆☆☆☆ Andu Tei · Jun 28, 2024
Garbage. Tried to measure gyro ball, doesn't work. Also doesn't close with return. Also takes your data.
★☆☆☆☆ Sierra G · Aug 25, 2025
Does not seem applicable to small engine (which was part of my Play Store search criteria).
