One Big Camera vs Reaction Studio

One Big Camera records both of your cameras at once. Most camera apps make you choose: front or back. One Big Camera captures them together and composites them into a single frame - so the moment and your reaction to it live in the same video. RECORD BOTH CAMERAS AT ONCE - Split screen - front and back stacked in one frame - Side-by-side - two cameras across the frame - Picture-in-picture - a floating facecam over the main shot, drag it anywhere - Portrait + Landscape - capture a vertical and a horizontal version at the same time Both cameras are live simultaneously. This isn't a front/back toggle - it's true multi-camera capture. A REAL EDITOR, NOT JUST A SHUTTER Everything you shoot lands in an in-app library built for making something, not just storing clips: - Trim with a frame-accurate scrubber - Add a voiceover - narrate over a clip and mix it in - Combine several clips into one video - Organize clips into projects - Share anywhere, or save to Photos SCREEN RECORD WITH YOUR FACE Record your screen with a live facecam bubble - perfect for reactions, tutorials, and walkthroughs. WHO IT'S FOR - Creators filming reactions, duets, and POV content - Vloggers who want themselves and their subject in one shot - Anyone tired of stitching two separate clips together by hand No account required to start. Everything you capture stays on your device unless you choose to share it. One camera was never enough. Make it one big camera.

React to anything. Reaction Studio lets you record your face over any video, edit it, and share straight to TikTok, Reels, and Shorts all on your iPhone. 2-WAY CAMERA Record your front and back cameras at the same time. React to whatever's in front of you in the real world, your face sits in a corner while the back camera captures the moment. REACT TO YOUR FEED Scroll your real TikTok, Instagram, or YouTube feed and screen-record it with your front-camera reaction overlaid live. You choose exactly what to capture. RECORD OVER ANY VIDEO Import from your camera roll or paste a link, then record your reaction picture-in-picture. Set exactly where the reaction starts, and resize, move, and style your camera box. FULL EDITOR Trim, split, and remove sections. Add captions, text, stickers, intros, outros, title cards, and a progress bar. Choose picture-in-picture, side-by-side, or split layouts. COMMUNITY Post your reactions to the feed, follow other creators, and collaborate on reactions together all built in. CLOUD BACKUP Save your reactions privately to the cloud so they're safe even if you lose your phone. Only you can see your cloud videos. SMART AUDIO — NO FEEDBACK Headphone detection, echo cancellation, noise suppression, and automatic speaker ducking stop audio loopback so your recordings sound clean. Control video and mic volume independently, mute either, or go full voice-over. EXPORT & SHARE Render in 1080p for Reels, TikTok, Shorts, feed, or landscape. Save to your camera roll or share anywhere in one tap. PRIVATE BY DESIGN Reaction Studio only records what you choose to capture. It never accesses other apps' data or feeds, and your videos stay private to you.
