UndoCam
Turn short videos into reversed rewind clips — pick a clip under 15 seconds, preview, then save or share.
Overview
UndoCam is a simple rewind-clip maker for iPhone. Choose a video of 15 seconds or less from your Photos library, and UndoCam plays it backwards — turning everyday moments, funny clips, and quick social posts into instant reversed videos you can save or share.
There is no timeline, no filters, and no complicated editing. UndoCam does one thing: it reverses the whole clip. You pick a video, watch the export progress, preview the result in the app, and then save it to Photos or send it anywhere with the share sheet.
Everything is processed on your device. Videos are never uploaded, and there is no account to create. Exports are rendered as stable 1080p/30fps muted video, prioritizing reliable results over preserving 4K or HDR source quality.
Who It Is For
- People who want a quick reversed-video effect for social posts, Shorts, or Reels
- Parents and friends capturing funny everyday moments to replay backwards
