interesting app. pretty good, not exactly 100 percent accurate, but close enough to get the job I was working on done. my brother and i were timing the engine of an old 280z, the tach in the car didnt work, this app was actually a huge help. I believe the option for 2 stroke and 4 stroke are backwards. was accurate as possible with the 2 stroke setting, and was way off on the 4 stroke setting. regardless not bad at all.

This is a very useful app. I use it to check out and calibrate boat tachs. For some owners of outboard motors, It is hard to set up a boat tach properly. It works with a "live" sound and recorded sound files which in some cases is more suitable. It is crystal accurate - I compared results with those obtained with a software spectrum analyzer.

This is one of the best tachometer options for single cylinder model engines. It has some limitations, for example when multiple engines are running, it can pick up both sounds and give strange results. Works on audio recordings just as well as in real time.
