Fuse – Merge & Trim Workouts

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.

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
- 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, cleaning up imported workouts, or preparing files for other platforms, Fuse makes your Apple Health workout history easier to manage.ed workouts, or preparing files for other platforms, Fuse makes your Apple Health workout history easier to manage.
