This app is working & has been tested but :

(!) If you have difficulty to use gps the first time, please restart your smartphone. After that all is working fine according to my tests.

(!) If you use Fitbit Versa lite, this app is a little long to install. Try to disable wifi connection to install. Be patient.

(!) This app need to some permissions (the most obvious is localisation/gps).

Using some cool display, this app shows 3 mods :

- actual speed

- average speed

- average stride width

It uses Fitbit's hardware technology.

For walking, running or anything (bike, car, tramway ;-) this time you need gps.

All the navigation is touchscreen, and double right click button (who puts exercise in pause).

Red's square to disable always on display.

This app is totally free but my rabbit loves littles gifts ;-) :
