Logging, history, and analysis

Logging workouts is fast and works from the iPhone or directly from an Apple Watch. Review past sessions with graphical summaries and detailed history, and use a configurable workout matrix for a clear overview of performance trends.

• Record sessions quickly, including Apple Watch entry.
• Examine historical performance with charts and trend views.
• Use a customizable matrix to compare workouts and progress.
