Easy belt tension
Thanks for the free app. Used on cvt v belt and timing belts. Clear instructions now ensure good measurements.

Terribly unreliable
I’m an audio engineer and I know for a fact that a carbon belt would not vibrate at 20,30,40,50,70,80 Hz with subsequent twangs. It must be reading the higher harmonics.
Mic simply doesn’t work. Very inaccurate.
Perfectly silent room, completely usable iPhone 15 Pro, readings are all over the place. Strum it 10 times, I’ll get 4 readings from 20-28 hz, a few readings around 40-50 hz, and the rest above 75 hz. There is no way I could trust taking any of these as an indicator or whether I need to go looser or tighter on my belt. Luckily I have the Gates Krikit gauge. I can click that thing 50 times and get 36 lbs every single time. I was more or less just hoping this app would be a useful reference out and about if I’m without the Krikit.
I give the app a couple stars for the calculator and suggested tension chart. But the microphone tool is no bueno and almost more of a liability in my mind. I’d be worried that someone is going to take their readings and go too loose and end up shredding their belt or worse they go too tight and cause the bearings on an IGH to explode.

Too sensitive, also doesn’t work anyway
First of all, I don’t do bike maintenance in an anechoic chamber. But even when I did get it as close to silent as possible in the real world (inside, heater off, no people or pets in the house, no moving my body except to pluck to belt, no breathing while the mic is on), I never could get four similar measurements with the crank in the same position (which seems like a prerequisite for trying it with the crank in different positions). A typical set of four would read something like 52 Hz, 98 Hz, 32 Hz, 87 Hz. Tried it on two different devices, so it’s not a mic issue. I give up.
