INSANELY precise app.

This app is AWESOME. I am not even measuring an induction motor. As long as your motor makes a clear tonal sound, and you adjust the settings according to the known specs of your motor, you will get an EXTREMELY precise measurement. I do have a tachometer and just wanted to see if this app worked. The reading I got off of this app was less than 5 RPM off of the reading on my tachometer. This app is perfect. The “load” setting needs a bit of work though. I Use this every day!
