Why it exists

Most small video apps do one thing and then make you export, re-import and do the next. Reversing a clip you have already trimmed should not take two renders and a trip through the camera roll. This app keeps the five edits people actually reach for on a single screen, lets them stack, and renders the result once. No timeline of twelve tracks, no text, no music library: a trimmer that knows how to run backwards.

Five tools, one pass

Trim, crop, flip, speed and reverse the same clip and it renders once. You never export, re-import and edit again.

  • Trim: drag the handles or split at the playhead, delete what you don't want, and the rest joins into one continuous video.
  • Crop: 9:16, 1:1, 4:5, 16:9 or freeform, previewed exactly as it will export.
  • Flip: horizontal or vertical, one tap each.
  • Speed: 0.25x to 4x, with a Keep Pitch switch so a sped-up voice doesn't turn into a chipmunk.
  • Reverse: real frame-accurate reverse, with the audio reversed too.

Export your way

  • Video (MP4) at original quality or scaled to 1080p or 720p, with an H.264 compatibility switch for older devices and apps.
  • GIF, with presets for messaging or social, or your own size and frame rate.
  • Audio only (M4A), to pull the sound out on its own.
  • Save to Photos, share directly, or save to Files.
  • Grab a still frame at full resolution from the playhead.

Privacy by design

No account, ever. Nothing is uploaded: every edit happens on the device, and nothing you import is kept after you export. No third-party trackers or ad SDKs.

Questions

Does it add a watermark?
No. Every tool is free, with no export limit and no watermark.
Is the audio reversed too?
Yes. Reverse is a real frame-accurate render, and the audio is reversed and re-encoded with it, rather than the picture alone playing backwards.
Can I combine reverse, speed and flip on one clip?
Yes. All five tools stack on the same clip and render in a single export pass, so you never export and re-import between edits.
Can it rotate a sideways video?
Not yet. Flip mirrors a video horizontally or vertically, which is not the same as rotating it. The Photos app's crop tool rotates a video in 90-degree steps.
What is free and what needs Pro?
Trim, crop, flip, speed, reverse and every export format are free. Advanced trim, cutting a clip into several pieces and dropping the ones you don't want, is Pro, as a weekly subscription with a free trial or a one-time lifetime purchase.
