1FIT

Record. Race. Replay. Understand.

1FIT helps you understand every Apple Health workout, create AI-ready exports, record outdoors, race your own routes and turn them into shareable Route Replay videos.

RACE YOUR GHOST
Save an eligible outdoor run, walk, ride or hike as a Ghost, or import a Ghost shared by someone else. Race the saved route on iPhone or Apple Watch while 1FIT compares your live progress, distance and timing. Manage, reorder and share Ghosts from their own place in the bottom navigation, and sync them to your paired Apple Watch for a focused, glanceable race experience.

RECORD OUTDOORS
Record outdoor runs, walks, rides and hikes on Apple Watch or an iPhone running iOS 26 or later. Follow live workout metrics, route progress and split callouts, pause or resume when needed, then save the completed workout and route to Apple Health.

REPLAY YOUR ROUTE
Turn a supported workout route into a polished vertical 3D Route Replay video. Choose the map style, route colouring, replay length, split markers, moving metrics, bottom stats and render quality. Rendering happens on your device, and privacy controls hide the beginning and end of the route by default so you can review the result before sharing an MP4 or saving it to Photos.

SHARE TO STRAVA
Create a Strava-compatible TCX file for a supported outdoor workout with GPS route data. Save or share the file, then upload it through Strava's file uploader. 1FIT only creates the file when you choose to export and does not upload workouts to Strava automatically.

UNDERSTAND YOUR WORKOUT
Browse your Apple Health workout history and calendar, then open detailed summaries with available heart rate, effort, splits, routes and sport-specific metrics. Create a Ghost or start Route Replay directly from a supported workout.

EXPORT FOR THE AI YOU CHOOSE
Create a structured Markdown copy of a workout, share it with your preferred AI or analysis tool and use built-in prompt suggestions to ask better questions. 1FIT never sends your workout to an AI automatically.

BUILT FOR EACH DEVICE
Use iPhone or Apple Watch to record and race Ghosts. On iPad, review workouts, manage Ghosts, create Route Replays and prepare exports on a larger screen. Personalise 1FIT with display themes, workout summary styles, Route Replay colours and alternate app icons.

PRIVATE BY DESIGN
Workout content is processed on your devices and stays there and in Apple Health unless you choose to export or share it. Ghosts can transfer to your paired Apple Watch. No 1FIT account is required, and limited app analytics do not include your Health data, routes or export content.

Apple Health availability and recorded metrics depend on your device, permissions, workout type and the data available for each workout. Route Replay and Strava-compatible export require a supported workout with route data.
