Introducing Split Screen React

The all-in-one reaction studio for Mac and Windows. The video plays inside the app while it films you, and it records every format you need in one go.

THE BIG ONE

Two videos from one take

Turn on Both and it records a wide 1920×1080 YouTube video and a vertical 1080×1920 TikTok at the same time. Each one is laid out for its screen, so nothing is cropped.

ZERO SETUP

Paste a link. That's it.

Drop in a YouTube or TikTok link and it plays right in the studio, picture and sound recorded with you. No screen capture, no scenes.

GREEN SCREEN, WITHOUT THE GREEN

"Over video" mode

You, cut out of your background, standing big in front of the video, the way the top streamers do it. Just pick it and react.

Questions? Answered.

Can I record my screen, like trading or a game?

Yes. Click "Record my screen or an app" and pick any window or your whole screen. On Windows the computer's sound is recorded too. On a Mac the screen and your mic are recorded, and macOS asks once for Screen Recording permission.

Do I need OBS or any other software?

No. Everything is built in, including the video tools for removing pauses and going live. You just need a camera and a mic, and headphones help.

Which computers does it run on?

Any Mac on macOS 12 or newer (Apple chip or Intel) and Windows 10 or 11. 8 GB of memory works, and 16 GB is smoother if you record both shapes in 1080p.

Is this a subscription?

No. You pay once and keep it.

Can I use my iPhone as the camera?

Yes. On a Mac, Apple's built-in iPhone camera works right away. For the front camera or the ultra-wide lens, on Mac or Windows, use the free Camo app.

Will the TikTok version just be my YouTube video cropped?

No, and that's the whole point. The vertical version is laid out separately for a tall screen, with the video on top and you underneath, or you big in front of it, so nothing important gets cut off.

Can I react to any video?

The app records whatever you play in it, but you're responsible for having the right to use the videos you react to. Reactions and commentary can be fair use, but it depends on what you add.

Windows says "Windows protected your PC". Is it safe?

The Windows installer isn't code-signed yet, so SmartScreen may flag it. Download it only from the link in your Gumroad receipt, and you can check the file against the SHA-256 checksum on the download page. If it matches, click "More info", then "Run anyway". Rather not? Ask for a refund from your Gumroad receipt within 30 days.

You Can Keep Editing Everything Twice… Or Record Once.

Your next reaction could be up on YouTube and TikTok tonight. The launch price only lasts for the first 100 copies.
