The tracking process can be started and stopped manually at any time in the app by pressing a button. For added convenience, an automatic tracking function is included in the app. The automatic tracking function uses various technologies and sensors in the smartphone, such as GPS sensors, acceleration sensors, barometer, Wi-Fi, Bluetooth, network location, compass or gyrometer, in order to detect the beginning and end of a journey. Data is saved only if a journey has been recognised. The automatic recognition of journeys is a function that uses technology that is still in its infancy. Errors in the process of recognition are therefore possible. We are working hard to improve the rate of recognition.
