ReelChains

Turn nearby phones into a synchronized camera crew.

ReelChains is phone-based, location-aware, time-synchronized, automated video production. Start or join a session and ReelChains finds the other phones near you — no group chat, no link to share. Everyone films the same moment from their own angle, and our servers stitch the footage into a finished video. Highlight reels, live music videos, split-screens, hi-fives, and more. No editing app, no post-production work.

A few of the things you can make

Same core engine — synchronized phones, automated cut — different output modes for different situations.

ReelChains highlight reel from a youth soccer game, showing multiple angles cut together.

Sports highlight reels

Parents on the sideline film their own kid from their own angle. Tap a moment, get a multi-angle reel of the play — wide for context, close-up for the touch, sideline reactions for the cheer. The scene director picks the right angle moment-by-moment so you don't have to.

Live music videos

A band plays one set; the audience films from wherever they're standing. We line up audio from every phone to the millisecond, then cut to the singer, the drummer, the lead guitar, the crowd — following the song. What you get back is an actual music video, from a single performance, made without a film crew.

Two people filming a hi-five — each side shows one face and one hand reaching toward the other, mirrored so the hands meet at the center of a split screen.

Hi-Five

Two phones, two people, one slap. Each side films their own hand and we mirror one frame so the hands meet in the middle of a split-screen — a perfectly-aligned shareable moment from a gesture that's actually impossible to film any other way.

Split-screen view of a basketball arena from two cameras — both frames captured the same shot.

Multi-view

Every angle, side by side. Any group of phones films the same window of time, and we lay them out as a synchronized grid or split. Use it for skate tricks, dance group performances, behind- the-scenes, demos, instructional clips — anywhere "show me all of it at once" is the point.

How it works

  1. Start or join a session. Open the app and ReelChains shows the sessions happening near you. One tap to join — no link to copy, no group chat to coordinate.
  2. Film from your spot. Each phone captures from its own angle. Time-sync happens automatically in the background.
  3. Get the finished video. Our servers pick the cut, mix the audio, and deliver the reel to every participant.
