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. ## Key features - Merge multiple workouts - Trim workout duration - Fix GPS gaps by drawing - Change activity type - Preview workout details - Export workouts (FIT/GPX) - Upload to Strava/Intervals.icu ## Chart rankings - #142 in Top Paid · Health & Fitness (US App Store) ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/fuse-merge-and-trim-workouts/id6760150004/reviews.md ### 5/5 — Strava-Import not Working? 🥺 *2026-06-05* Good App, does as advertised! 👍🏼 It would be a charm to have the following two features working: - Strava import is broken 🫠 - Which data streams are being combined? Let the user choose which ones they want (e.g. for cycling: GPS data, power, heart rate…) **Developer response:** Thanks so much for the kind words and the thoughtful feedback — this is exactly the kind of report that helps. 🙏 On Strava: You found a real one. New Strava-connected apps start in "Single Player Mode," which (unintentionally) limited connections to just my own account — so it worked in my testing but failed for everyone else. I've raised the app's capacity, so Strava upload should now work for you. Please give it another try and let me know if you still hit a wall. On choosing data streams: Great news — this already exists, it's just buried. In the Merge Preview screen there's a "Data Sources" section where you can pick, per stream (GPS, power, heart rate, cadence, etc.), exactly which workout's data to keep, and even leave a stream out entirely. You're right that it's not obvious enough, so I'm making it more prominent and adding simple on/off toggles per stream in an upcoming update. Really appreciate you taking the time — feedback like this directly shapes what I build next. Cheers! 🚴 ### 1/5 — Doesn’t work *2026-03-20* App doesnt work for even basic use cases **Developer response:** Thank you for your feedback. Before Fuse was published, it was tested extensively by a wide group of users across a broad range of workout types — so we're genuinely surprised to hear about this experience. We'd love to understand what specifically didn't work for you, as this would help us identify and address the issue quickly. Please reach out to us directly at and we'll make it right. We take every report seriously and are committed to making Fuse work flawlessly for everyone. ## Frequently asked questions about Fuse ### What is Fuse?
