Description

This application has been designed for ultra-runners who want to use their AppleWatch during their ultra-trail workout. The application includes a specialized cartography and a simple interface which allows you to concentrate on your run.

IMPORTANT: To support very long runs, the workout is recorded by the iPhone. The AppleWatch is used for displaying the metrics, the cartography and to record heart rates but is not mandatory and can be charged during the run without interrupting the recording.

Features include:
- Specialized cartography
- GPX track display, including elevation graph if available in the GPX.
- Trail run recording with Apple HealthKit support
- Heart rate colored zones (Premium)
- Phone and Watch battery status display on the AppleWatch.

Premium functionalities will require a subscription in future versions.
