# Fix My Workout > Fix My Workout is an iPhone app that corrects workouts in Apple Health. Apple Health does not let apps change a saved workout, so the app saves a corrected copy, checks it after saving and leaves the original unchanged. Free download with 3 fixes; one in-app purchase unlocks unlimited fixes. There is no subscription and no account. Requires an iPhone with iOS 18 or later. Developer: Dan Urbánek, an independent developer. Former App Store names: Treadmill Workout Fixer, Fix My Treadmill. Available in more than 40 languages. ## What it fixes - Distance and pace: enter the real distance, for example the one a treadmill console showed. Pace, speed, stride length and laps are recalculated; the time stays as recorded. - Laps and splits: six methods. Spread evenly, anchor and remainder, preserve structured splits, duration weighted, rebuild 1 km or 1 mi splits, or keep measurements without the original intervals. - Active calories of gym workouts such as HIIT, yoga, Pilates, strength training and boxing. - Trim: remove time from the start or the end. Only the selected time range is kept. - Join: two compatible recordings of one session become one workout. The user chooses which recording counts where they overlap. No distance is drawn across the gap between two routes. - GPS distance: for outdoor runs, walks, rides and hikes with a route, the app measures the route along reliable GPS sections only (poor accuracy, signal gaps, pauses and jumps are skipped) and the user chooses that distance or the recorded one. Route points are never added or deleted. - Activity type: change a workout saved under the wrong type. - Elevation gain and loss on supported outdoor workouts. - Missing distance: add a distance that was never recorded to a run, walk, ride, hike or open water swim. - Charts: heart rate minute by minute over time or distance, time in the user's saved heart rate zones, and every metric before and after the fix. - Optional workout alerts for new workouts and for recordings that could be joined. ## Files - Import: open a .fit file from Files, Mail or the share sheet, review it, then confirm. Nothing is written to Apple Health before that. - Export the original or the fixed workout as FIT, TCX, CSV (16 fixed columns) or JSON (with a machine-readable contract of units, sources and coverage), and as GPX when the workout has a route. ## Supported workouts 21 types: indoor and outdoor runs, walks and rides, pool and open water swims, hiking, stair climbing, elliptical, HIIT, mixed cardio, yoga, Pilates, core training, flexibility, traditional and functional strength training, climbing and boxing. The fixes on offer depend on the activity and the data it recorded. ## Privacy Workouts are processed on the device. Health data leaves the iPhone only when the user exports a file or chooses to send diagnostics. Anonymous app statistics go to TelemetryDeck and never include health data. ## Guides - [Apple Watch treadmill distance wrong?
