Is it possible to use RaceChrono on Android without a Sim Card inserted? I am using a Galaxy Note 5 as a standalone device for my lap timing, it does not have a Sim Card, so therefore no data. I am using a Garmin Glo that is connected via Bluetooth. When I select Start then try and select a track nothing shows up because of no data, but my question is can I select my track at home using my home wifi and 'pre load' the track I will be visiting the following day? Will it save in the program for later use. Or do I need data the entire time RaceChrono is recording my laps?
