MarschRide app
A bike-computer with BLE-sensors, a offline map and GPX-RecordingRecord your location, pulse, speed and cadence to GPX-Format.
Drive without SIM-Card with a pre-downloaded OSM-Map
Use your old device (Device-Support down to KitKat)
(Exportet GPX-Format can be used in Relieve to make videos from it or you can share your favorite routes
to others using various other online services)
Note: Background-Recording (when screen off) does not work for the moment.
The screen will be kept on instead. Will try to fix this with the next update
