BikeGPX is the best way to navigate fixed-route rides such as charity rides, sportives and audaxes where a GPX file has been provided by the organizer, as well as routes you plan yourself in advance. - Easily send GPX files to your phone from your Mac or PC - no account required - Off Route Alarm plays a sound if you go off your route - On-screen Elevation Graph shows what big hills are coming up (in-app purchase required) - Sharp Turn Alarm looks for upcoming sharp turns and plays a warning sound (in-app purchase required) - Route ahead highlighting indicates which way to go when different parts of the route overlap - User accounts allow access to your routes from multiple devices - Routing continues to work when the app is backgrounded or the phone is in sleep mode - Optional track recording, so you can export your ride as a GPX when completed - Support for Bluetooth speed/cadence sensors, heart rate monitors and power meters Note: Continued use of GPS running in the background can dramatically decrease battery life.
