What's New in Endurance Debrief
2.0.1
August 1, 2026
Two fixes around Apple Health. • "Re-import Health workouts" now keeps the workouts you replaced by loading the original file. They used to be reverted to the less detailed Health version. • The heart rate check also looks inside your recent workouts. It no longer claims a missing permission just because you haven't trained for a few days. Nothing changes in the calculations.
