ReelDuo: Dual Camera Recorder

ReelDuo records once and gives you every format you need to post.

Every Solo recording saves two files from a single take: a vertical 9:16 for TikTok, Reels and Shorts, and a horizontal 16:9 for YouTube. Both are perfectly synced, and both are ready to upload. No reshooting, no re-cropping, no editing app in between.

Duo mode records your front and back cameras at the same time into one vertical video, with a picture-in-picture you can drag and resize. It is built for reactions, commentary and pieces to camera. Duo needs a phone that supports running both cameras at once; where that isn't available ReelDuo hides it, and everything else works as normal.

A built-in teleprompter scrolls your script over the viewfinder at a reading pace you choose, so you can look at the lens instead of your notes. It never appears in the recording.

ReelDuo Pro is a one-time purchase. No subscription, ever.
