Overlay.fit

Turn your workout videos into shareable Reels and TikToks - with your real heart rate, power, speed, cadence, pace, elevation, and route overlaid on top. overlay.fit takes a short clip you've already filmed and a workout file from your watch or bike computer, and exports a finished 1080p portrait video ready to post.

Built for phone-first cyclists and runners who don't want to sit at a laptop running desktop video software. Import a FIT, GPX, or TCX file from your device, pick a template, trim, and render. Pull workouts straight from Strava with a one-tap connect, or from Apple Health to bring in anything your Apple Watch, iPhone, or third-party fitness app (Strava, Nike Run Club, Fitbit, and more) has written there. Most clips finish in under a minute on a modern iPhone.

WHY OVERLAY.FIT
• Phone-native. No desktop. No exporting between apps.
• Templates that look great by default - no fiddly dashboard configuration.
• Save your own templates to re-use.
• Drag-and-drop widgets. Place any stat anywhere on the frame, resize with pinch.
• Direct share to Instagram Reels, TikTok, or anywhere else.

WIDGETS
17 stat widget variants and counting - speedometer gauges, heart-rate cards, power bars, cadence dials, elevation profiles, pace breakdowns, and a live route map that follows your ride. Per-stat unit toggles (mph/kph, watts/W·kg, bpm, ft/m). Free-form placement: drag, pinch to resize, double-tap to remove.

WORKOUT SOURCES
• FIT files - Garmin, Wahoo, Coros, Polar, Suunto, Apple Watch (via Workouts → Export, or the Health app's GPX export).
• GPX and TCX files - from any service that exports them.
• Strava - one-tap connect, no copy-pasting tokens. Recent activities load instantly.
• Apple Health - import workouts captured by your Apple Watch or written there by any other app on your phone. Heart rate, distance, instantaneous speed, power, cycling cadence, and GPS route (with altitude) all flow through.

FOR
• Cyclists posting climbs, intervals, sprints, gravel rides
• Runners filming race finishes, hill reps, long runs
• Triathletes building post-race highlight reels
• Anyone with a GoPro clip and a watch file who wants the two combined

PRO
Unlock the full quality slider, remove the watermark, and skip the rewarded-ad gate before each render with overlay.fit Pro. Available as a monthly or yearly subscription - start with a 7-day free trial, cancel anytime in Settings → Apple ID → Subscriptions. The free version is fully functional - you can render, share, and post as many videos as you like without upgrading.

PRIVACY
Your videos, activity files, and Apple Health data stay on your device - we never upload them. Strava data is fetched over HTTPS only when you ask for an activity, and discarded after the render. We don't sell or share your data.
