The app provides location information in your preferred units for speed, course and altitude. Additionally, the phone app collects and calculates derivate information such as distance travelled, maximum and average speeds, highest and lowest altitudes and ascent and descent, and provides a compass.
The watch app can run independently, but the also phones derivate data is visible in real time in the watch. The watch app can used to remotely connect the phone: start or stop the trace, reset derivate information or pause both devices.
The location data can be saved to a GPX trace: you can follow your current position, active trace or stored traces on the map.
