With this app it is possible to control the BangleJs. You can start and stop recording of activity data, as well as send the data to a previously configured server. To be able to use the app, it is urgent that our operating system "Activate" version => 7.1 is installed on the BangleJs. Downloadable from here: https://kristofvl.github.io/BangleApps/.
Please mark the Bootloader, Settings, Launcher and the app "Activate-Test" as your favourite and install them via About -> Install favourite apps.
