Twofold: Dual Camera Recorder

Film the scene and your reaction at once with both cameras, in Photos the moment you stop. Free: no watermark, no ads, no sign-up. New: export each part for AI editing.

Film with the front and back cameras at once: the scene and your reaction, in one take. Free, with no watermark.

Twofold records the scene in front of you, your reaction to it, and when and where it happened, all in one take. The front and back cameras film at the same time, so a walk through a new city, a concert, a day out with the kids or a walk-and-talk vlog becomes one video with you in it. No switching cameras, no stitching clips together afterwards.

ONE TAKE, READY TO POST

• Stop recording and a picture-in-picture video is already in Photos, ready to share.
• Both cameras are also kept as separate original tracks, so nothing is lost.
• Vertical 9:16 by default; the small window sits in the upper left, clear of the buttons social apps put on the right.

PICTURE-IN-PICTURE, TOP AND BOTTOM, SIDE BY SIDE

• Three layouts: picture-in-picture, split screen top and bottom, or side by side.
• Drag the small window anywhere, pinch to resize it, double tap to swap the two cameras.

PHOTOS FROM BOTH CAMERAS

• Switch to Photo and press the shutter: the front and back cameras take a picture at the same instant, saved to Photos as one.
• Use the flash, and change the layout later in the library.

CHANGE THE LAYOUT AFTER RECORDING

• Wrong corner? Face should have been the big picture? Open the recording in the library, move, resize or swap the window, pick another layout, and export again. No reshoot.

EXPORT EVERY PART, RECUT WITH AI

• Open a recording in the library to export the final video, either camera's original or metadata.json on its own, or everything as one .zip.
• metadata.json records where each original sits on the timeline, the layout and every change made while recording, so another editor, a script or an AI editing tool can line the two cameras up and cut them again.

REMEMBER WHEN AND WHERE

• Put the time, the date, the place or the coordinates and altitude on the video, and change or remove them after recording.
• Drag and pinch the overlay to place and size it; the Place overlay shows the name of the place.
• Your location is read only when you choose a place overlay, and goes nowhere but into the video you save.

BUILT NOT TO LOSE A TAKE

• Recordings are written in pieces as you film and recovered after an interruption or crash.
• When the phone gets hot, quality steps down gently and the viewfinder says so, instead of silently dropping frames.
• Recording stops in time when storage runs low, and keeps what was filmed.

READY WHEN YOU ARE

• Opens straight to the viewfinder.
• Switch between HD and 4K, 30 and 60 fps right in the viewfinder, and film landscape even with rotation lock on.
• Start and stop with the volume buttons, the Action button or Camera Control.
• Add Twofold to the Lock Screen and Control Center to start filming without unlocking.

PRIVATE BY DESIGN

• No account, no sign-up, no ads.
• Your videos, sound and photos never leave your iPhone.

FREE, WITH EVERYTHING INCLUDED Twofold is free, with no watermark, no limit on the length or number of videos, and no ads: every feature is included, from 4K and 60 fps (where your iPhone supports it) to 3:4 and 16:9 export, every picture-in-picture style and separate voice and ambient sound tracks.
