Fuse helps you take control of your Apple Health workouts.
If a workout gets split mid-session, Fuse lets you merge multiple recordings into one complete activity. If a session includes extra time you don't want, trim it down and save a cleaner version back to Apple Health.
Lost GPS signal mid-workout? Draw the missing part of your route on the map and Fuse rebuilds it, distance included. Saved a session as the wrong activity type? Change it in a couple of taps — your route, heart rate, and metrics stay intact.
Before making any changes, you can review full workout details — including route data, heart rate, duration, distance, energy, laps, and segments.
With Fuse, you can:
- Merge multiple Apple Health workouts into a single activity
- Trim a workout to keep only the section you want
- Fix GPS gaps by drawing the missing route directly on the map
- Change a workout's activity type (for example, Indoor Walk to Outdoor Walk)
- Preview workouts and see gaps before confirming a merge
- Choose whether to keep or remove originals after merging
- Upload workouts directly to Strava or Intervals.icu
- Export workouts as FIT or GPX files
- Browse and filter your workout history by activity type
- View full workout details with maps, heart rate charts, and key metrics
Fuse is built for athletes who want cleaner records, better exports, and full control over their training data — without unnecessary complexity.
Whether you're fixing auto-split sessions, repairing GPS gaps, cleaning up imported workouts, or preparing files for other platforms, Fuse makes your Apple Health workout history easier to manage.
