How does Better Workouts work?
Better Workouts reads the Health data stored by the Workout app from Apple Watch or by manually importing data from a FIT file. While it may be able to read workouts stored in the Health app by third-party apps, some details may be missing.
The app includes charts not available in the Fitness app on your iPhone. Some examples include cycling speed, running pace, heart rate, heart rate zones, cycling cadence, dynamic splits, elevation and more. Better Workouts shows you data in a clean and simple format.
