I installed this app not thinking it'd work or be anything special. Immediately used on 2 different 4 stroke single cylinder 5 hp engines. A Briggs and Stratton and a Predator. 1 constant governed speed and 1 throttled. It read both very accurately. I can see me upgrading before trial ends. Actually pretty impressed...

Works great! Not always perfect but as good as you can expect from a smart phone that was not designed to be a tachometer. And for $5.99 for lifetime access, I would definitely recommend.
