After downloading , launch the app . It is pretty selfexplanatory . You need to setup its settings . You have a choice of setting it up to collect data actively or passively or , not to contribute though I don ' t know why anyone would select this choice . If you choose , ' Active ', then when about the begin a trip , open it and select ' Map a Trip ', then press the ' START ' button . The apps timer will start running and will run until you press the ' STOP ' button . In the uppermost lefthand corner of the app are the three lines indicating the app ' s menu . Go in there and set up the General Settings you desire and under ' Report to server ', set it up to download your data only when on WiFi and or only while charging . This will save on your data amount on your plan and your battery . Thanks for your contributions !
