Record your face over any video, edit it, and share straight to TikTok, Reels, and Shorts — all on your iPhone.
Everything you need
Capture, edit, and publish polished reaction videos — no other apps or desktop software required.
Scroll your real TikTok, Instagram, or YouTube feed and record the screen with your face cam overlaid live.
Import from your camera roll or paste a link, then record your reaction picture-in-picture.
Headphone detection, echo cancellation, noise suppression, and auto speaker-ducking stop audio loopback cold.
Trim, split, remove sections, captions, text, stickers, intro/outro, title cards, and a progress bar.
Picture-in-picture, side-by-side, vertical or horizontal split — resize and style your reaction box.
1080p for Reels, TikTok, Shorts, feed, or landscape. Save to camera roll or share anywhere in one tap.
Four steps
Reaction Studio keeps the whole flow inside one app.
Screen-record your real feed, import from camera roll, or paste a link.
Watch while your front camera captures your face — with feedback protection on.
Trim, add captions, stickers, and choose your layout and aspect ratio.
Render in 1080p and post to TikTok, Reels, Shorts, or save to your roll.
Reaction Studio only records what you choose to capture. It never accesses other apps' data or feeds — you scroll your own feed while screen recording, and everything stays on your device.
