Field notes
The setup sequence is phone mount → car-stereo connection over Bluetooth, USB, or cable; the page says the app calibrates to the mount and uses phone motion sensors plus GPS. It lists a free tier with the simulator, Sound Studio, Workshop, timers, trip statistics, and recordings; Live Drive is separately priced at $2.99 yearly or $14.99 lifetime. The homepage also says playback stops when the car audio disconnects and resumes when that same car reconnects.
