I found it virtually impossible to achieve consistent readings, often experiencing really wide fluctuations. It's also a pain to reset so it takes a while to accumulate a series of readings. Added to this ... the 'acceptable' tension ranges are quite wide, so you're really left scratching your head as to what to do. I will buy one of the manual tension clickers for this job.

Excellent! Worked well on my Galaxy Note 3. Consistent readings. Checked it against G-Strings guitar tuning app and was within 1 Hz. Can't beat that! My only complaint: they should better identify the icon you tap to start the test - it took me a while to find it.

Worthless app on android. Poor instructions and will not function. Tried from galaxy tablet and phone......nothing. freq. function won't work.

Android app doesn't work very well. It only read 50 once, now way to reset the previous measurement. Had to kill the App from Task manager to reset and attempt to measure again. Will use the Apple app on son's iTouch

Great idea for an app; the instructions don't match the actual process which was confusing. Also inconsistent readings.

This app is amazing for belt tensioning I don't have a bicycle, I was able to use this app to tension a belt on my car and it worked flawlessly.

Not for Android (Galaxy S6) Either every sprocket, gear, and belt length requires the identical tension (in which case, why list them?), or the app doesn't work.
