Comments on Engine RPM for Android

★★★★★ Ates Gurcan · Jul 8, 2022

Finally, a tachometer that works with my model diesel engines. Quite accurate. I used it to measure RPM off of recorded videos, from live engines with good results. The looks could be improved, but the performance makes up for it. Thank you!

I use this to "break in" my electric motors I use for Tamika Mini 4wd racing. I previously used Giri and this app works much better and gives the user far more finite control. Highly recommend and well worth the price. Plus this can be used on my android phone where Giri is for Apple phones.

★★★★★ Josh Ely · May 6, 2024

Perfect! As an advanced diy small engine mechanic I wanted to be able to get a rough idea of engine rpm without getting my phototach or inductive pick up out. This did exactly what it says. Tested on 3 small engines (Honda GV160 and Briggs L-head) and the initial results seemed too accurate. So I decided to pull out my clamp on rpm meter. There was always less than 2% difference and usually a 1% or less difference. All tests were between 2,600 and 3,400 rpm. It's worth double what they charge!

Inaccurate, not user-friendly, would not purchase again
