Description

Gates Carbon Drive is the high-tech belt drive for bicycles, motorcycles, & scooters. This app measures belt tension sonically. Just pluck your belt like a guitar string and use the microphone on your phone to read the vibration frequency. Compare your bicycle belt’s frequency to the included chart to see if you need to adjust the tension. For scooter/motorcycle tension recommendations, compare to your vehicle owner’s manual.

Interface

Dark blue text on a dark background is really hard to read.
Should have clear images or short video showing exactly where to hold and how to pluck belt.
Feels like it was designed by engineers and for people who already know what they are doing, not for the first time user.

Doesn’t work, erratic measurements

Plucking the belt I get anything between 39 and 87 at the same spot. Obviously not a reliable way to measure tension.

Interesting but not repeatable.

This is a really interesting idea, and double concept to check the belt tension. Unfortunately, every time I pluck the belt it resonates at a different frequency. I suppose a rule of thumb for testing manually is probably good enough.
