Fuse – Merge & Trim Workouts
Pay Once. Own It Forever.
1,99 € · Designed for iPad. Not verified for macOS.
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.

Draw to Fix GPS Gaps
Lost signal in a tunnel or under tree cover? Now you can finger-draw the missing stretch of your route right on the map. Fuse rebuilds the path and recalculates your distance — no more broken maps or straight-line jumps across town.
Change Workout Type
Recorded an Indoor Walk that should've been an Outdoor Walk? Convert any workout to a different activity type in a couple of taps, with all your data kept intact.
Plus general improvements and fixes.
