KuaFu: Workout Video Dash

KuaFu overlays workout telemetry from FIT files onto your action video so speed, distance, riding time, altitude, and your GPS route stay in sync with every moment on screen.

Pick a clip from Photos, import a FIT file from your bike computer or sports watch, align the timelines, choose a layout, and export a share-ready video.

HOW IT WORKS
• Import video from your Photo library
• Import a FIT file with clear validation when parsing fails
• Auto-align video and workout data, then fine-tune with manual offset
• Choose metrics and layout presets for speed, time, distance, riding time, altitude, and route
• Preview overlays on your footage before export
• Export at original quality or 720p / 1080p presets

KEY FEATURES
• FIT-first workflow with graceful fallback when a field is missing
• Speed styles: text, dial, or large number
• Time, distance, and riding-time overlays with flexible formatting
• GPS route overlay: full-screen trace or corner mini-map
• Layout presets plus drag-and-pinch overlay adjustments
• Readable overlays with contrast and opacity controls
• Save finished videos to Photos or share elsewhere

PRIVACY FIRST
Video and FIT files are processed on your device by default. KuaFu does not upload your footage or workout tracks as part of normal editing.
