Carbon Drive Belt Tension Tool

App does the job well when running. Crashes in use though. Time for an update guys. Not a good reflection for Gates as a company. Update please to fix issues.

No longer opens. Crashes immediately upon opening. It worked in the past.

I own a priority 600, & this app does help with tensioning the belt when used correctly in a quiet room, but it could be much easier with a simple feature. Please add a “pause button” for in between “plucks” I can’t rotate the crank 1/4th turn without a bike stand else I get a false positive because of other small noises.

Cool Idea, doesn’t work well. Spouts out random readings when I’m not plucking belt, then spouts out values from 20hz to 70hz when I’m plucking the belt.

The app does not have a “record” or measure button. Thus it is unclear when no measurement is recorded whether I’m using the app wrong, if my belt is set wrong, or if there is too much background noise or other problems. I was able to get the app to work one time, but since then have never gotten any measurements recorded.

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

iOS 14.3. App needs updating. Useless now.

This is a good tool if you don’t have access to Gates Krikit gauge or Eco Tension tester. Variations to a degree are to be expected. It is the nature of slight variations in cranks, bb’s, chainrings and sprockets.

Please update to cover the 174T belt with smaller 4bolt pulleys now being put on tandems. Thx

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.
