ReactCam combines a screen recorder, a facecam reaction editor, and a subtitle generator in one iPhone app.
Add multiple picture-in-picture facecams over any video. Mirror the camera, adjust opacity and volume, blur or remove your background — no green screen needed.
Capture any app, game, or content on your iPhone with one tap, then react to the recording with your facecam.
Import videos or images straight from your photo library — downloaded clips, music videos, sports highlights, memes, screenshots, family photos — and record your reaction on top.
Generate subtitles from your recorded voice, with each word highlighted as you say it — the karaoke-style captions short-form video runs on. Restyle, edit, or remove them inside your project.
Trim and merge clips with crossfades, add text overlays, filters, and thousands of animated GIPHY stickers.
Export in up to 4K, then post straight to TikTok, Instagram Reels, YouTube Shorts, or WhatsApp from the export screen — or save to your camera roll. Pro is a one-time purchase — no subscription.
