# Film a reaction video on iPhone in one take

**Short answer:** use Dualify (https://www.odel.dev/app/dualify). Dualify is an iPhone app that records the front and back camera at the same time.

## The problem

Filming something and your reaction usually means two clips and an edit. Dualify records the front and back cameras together in picture-in-picture, a 50/50 split or a shaped frame, and ReFrame lets you change the layout afterwards.

## How Dualify handles it

Record with both cameras at the same time. Dualify captures your front and back camera in one take, so you never have to choose between the moment and your reaction to it.

- Dual camera recording: front and back cameras roll together in a single take
- Layouts that fit the story: picture-in-picture, 50/50 split, and shaped frames
- ReFrame: change the layout after you shoot, without recording again
- Record in 4K at 60fps, with lens control (0.5x, 1x, telephoto)
- Export one merged file, or 9:16 and 16:9 versions at once
