I don't know what the bad reviews are talking about. I almost deleted this app before trying it, but after plucking my Zero's drive belt three times using a wrench I got 59 Hertz every single time.

Helps you get the tension right on your Gates belt drive. Amazing that this works. And it does!

Used this to tune the belts on a 3D printer. It worked flawlessly. Appreciated it storing the last 4 plucks; this ensured accurate, repeatable readings. Put your phone microphone within an inch of the belt, ideally on a stable surface, in a fixed position.

Worthless as far as I can tell. It gave readings on the tension of my belt that varied wildly from 20Hz all the way up to 103.

This app is good only to remind yourself what the acceptable frequency range is for your bike. The frequency detection is useless. Instead, use the Spectroid app with these settings: Sampling rate: 16kHz FFT size: 8192 Decimation: 1 Window: Hamming Smoothing: 0 After plucking the belt you should see all frequencies jump, but one frequency will decay slower than the rest, and Spectroid should detect it as a peak. That's the fundamental frequency that you're trying to adjust.

It's giving stupid random results and not even detecting plucking the belt. I'm doing everything it said and it's not working.
