Video tachometer for Android

Agreed to +- 10 percent with laser tach, and I think this may the more accurate measurement. Only feature I would like to see added is a slow phase shift mode about the determined frequency.

This app works great for checking rpm on our irrigation gearheads. I used to always carry a handheld tachometer with me but not any more... I've been using this for over a year and it's the greatest tool always in my pocket. Thanks

I used this app to measure and adjust the RPM of my evaporative cooler. Found one of my coolers was spinning at almost half the recommended rate. Fixed using an adjustable pulley. Thanks for a great and useful app.

It actually works! No annoying crap, no ads it seems. I bought the full version for $2 to support the developer.

I was about to go buy a tachometer when I remembered there were strobe light apps. This is stupid east to use and as long as you’re ok w/ 10 rpm increments you don’t need to pay anything. I will say it’s a little hard to measure sub 200 RPM, although at that point you may be better off filming it in slow motion and counting the cycles
