Chronoburn

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 — Minimal timer face included; unlock Retro LCD, Scoreboard, and Egg Timer dial faces — One-tap export to your Photos library

Chronoburn is fully offline. No account, no sign-in, no data collection, no ads — every video stays on your device and nothing ever requires a network connection.

One-time purchase unlocks every timer face, forever. No subscription.
