iPhone
Chronoburn burns a running stopwatch or countdown timer directly into your video — permanently, at export, so the clock is baked into the footage itself. Built for anyone reviewing workout sets, timing a recipe, or logging a timed practice drill who wants the time visible in the clip afterward, not just on-screen while filming.
Position the timer by dragging it right on the video preview. Resize it with a pinch. Pick a start point and tap the timeline to freeze the clock exactly when you rest between sets or cut between takes, then let it run again. What you see in the live preview is exactly what gets burned into the exported video.
Included
— Drag-to-place, drag-to-resize timer overlay with a live scrubbing preview
— Count-up (stopwatch) and countdown modes
— Tap-to-freeze markers on the timeline — pause and resume the clock with no keyframe editor
— Four timer faces: Minimal, Retro LCD, Scoreboard, and Egg Timer dial
— One-tap export to your Photos library
WHAT MAKES CHRONOBURN DIFFERENT
Most video editors treat a clock as a text overlay buried in a timeline. Chronoburn makes the timer the whole product: drag, pinch, and tap-to-freeze — and the live preview is exactly what gets burned in, frame for frame. Fully offline. No account, no sign-in, no data collection, no ads.
PRICING
Chronoburn works out of the box with the Minimal timer face; exports carry a small Chronoburn watermark until you upgrade. Chronoburn Pro unlocks every timer face and removes the watermark — choose the monthly subscription (3-day trial, cancel anytime) or a one-time lifetime purchase. Prices are shown in your local currency in the app.

This release makes the Pro paywall more reliable: prices now retry automatically on slow connections instead of failing, and Restore Purchases is always reachable. The timer face can also be resized with a two-finger pinch, and the app is now fully localized in Chinese.
