fx12 is the companion app for Favionics fx12 / fx24 timers, fxRDT, and fxWS devices. It gives you a clear interface to view and change parameters on fx12 and fxRDT, including altimeter and GPS data in real time. The optional Apple Watch app shows live telemetry and lets you RDT the model from your wrist. This app may use your location even when it isn’t open, which can decrease device battery life. Continued use of GPS running in the background can dramatically decrease battery life.
