Video Collage Builder

Make multiple videos move together.

Video Collage Builder is a video collage editor for combining clips into a single frame — side by side, stacked, or in a grid — with proper audio sync so everything plays in time.

What you can do:

• Combine multiple videos in one frame

• Crop and trim each clip independently

• Sync videos to each other, or sync them all to an audio track

• Export straight to Photos

Built for:

• Dancers comparing takes or breaking down moves

• Musicians lining up multi-angle performance footage

• Athletes checking form against a reference

• Anyone who wants two or more videos to play together, in sync

Privacy by design:

• Fully offline — no account, no upload, no servers

• Your videos stay on your device

• No tracking, no ads, no in-app purchases

App runs entirely on your phone. Nothing leaves it.
