App Icon



An app that measures G-Force using the Garmin accelerometers. It shows current G (should be about 1) and then Max and Min G.</p><p></p><p>Created for a bit of fun in the velodrome. At the moment it picks up too much road vibration to be very useful, but it is a little bit interesting.</p><p></p><p>Be warned it drains the battery quite a lot. </p><p></p><p>There is a known bug that is angle dependant, when a watch is sitting flat on a surface gravity seems to be 0.9G, but on the side 1G.

What’s New

Added callibration and tried to smooth the data a lot...</p><p></p><p>Update so that the smoothing level set on the phone hopefully works

Fenix 3. Would love to see it working, but honestly, I have no clue what the 7 (!) Shown numbers do. I guess some of them should not be visible at all.

Fun app. On the Fenix 3HR it shows 0,25G initially instead of 0G in rest. Furthermore some ‘ghost’ data is displayed on the left and right site of the top and middle displayed G-data. Unclear what the acutal, min and max values are. The bottom one always displays 0G. Also a ‘reset’ button would be nice, now you need to quit the app and restart.

Does Edge 520 have a built in accelerometer? values are fixed in 1.05 0.25.083 good idea but...
