About this app
Calculate the rpm, depending on the engine sound.
Through the calculation frequency, the sound is analyzed to determine the revolutions of an engine.
It is necessary to indicate the characteristics of the engine prior to reading.
Many negative ratings are due to not having configured the application correctly. Please make sure you understand how to set it up before giving a negative review.
May not work on all engines. It works worst with engines with the exhaust sound very muted and mechanical noise engines (air cooled engines).
It is normal to show random values when the engine is not running.

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.

Interesting project, I was testing this aginst an outboard 200 hp two stroke on YouTube with a recorded rpm meter. This app was spot on in certain circumstances but fell down too low. The highest numbers in this app was usually the most correct. But could not substain to be precise. When it was a change in rpm it corrected to be precise and fell to low again. Anyways great work.
