Some moments need two views: the thing being watched, and the face watching it. ReactCam plays a video on your phone while the front camera records the reaction — or rolls both cameras at once, so you keep what you pointed at and your own face seeing it. One take, in sync, nothing missed. HOW IT WORKS 1. Choose what they'll react to — a video from your Camera Roll or Files — or just roll both cameras live. 2. Hit record. ReactCam captures their face and the source video together, in sync. 3. Lay the two videos out however you like, balance the sound, and save straight to Photos. RECORD BOTH SIDES AT ONCE Dual Camera runs the front and back cameras together, so you catch what happened and who saw it in a single take. REACT TO ANY VIDEO Import from your Camera Roll or Files and react while it plays. The video and the reaction land in sync, every time. LAY IT OUT YOUR WAY Drag to move, pinch to resize. Put their face where it belongs, at the size it deserves. Works in portrait and landscape. BALANCE THE SOUND Independent volume for each track, so the reaction never gets buried under the video — or the other way round. KEEP EVERY REACTION Projects holds on to your recordings, so you can come back later, change the layout, and export again. Nothing is locked to the first version you made. PRIVATE BY DESIGN Everything happens on your iPhone. No account. No uploads. No tracking. No data collected, ever. Your videos never leave your device — which is exactly what you want from an app you point at your family. REACTCAM PRO Free to try, with 5 exports and 5 saved projects included. Unlock unlimited exports and projects with a single one-time purchase. No subscription, no ads, no watermarks.

Dual Lens turns on both iPhone cameras at the same time. The back camera captures what's in front of you, the front camera captures you, and both end up in one frame. TEMPLATES • A round bubble over the main picture — made for trips, concerts and vlogs. • Rounded square and a portrait 3:4 window. • Split screen: top and bottom, or side by side. • One tap swaps the cameras, so the small picture becomes the big one. MAKE THE WINDOW YOURS • Size and corner radius — from a sharp square to a perfect circle. • Nine preset positions: corners, edge centres and the middle. • Or drag the window anywhere right on the preview. It snaps to a preset when you let go nearby. • A border in any width and colour. • Save your own templates and switch between them with one tap. EVERYTHING YOU EXPECT FROM A CAMERA • Tap to focus and set exposure — on whichever camera you tapped. • Swipe up or down after a tap to brighten or darken the shot. • Touch and hold for AE/AF Lock. • Pinch to zoom or use the lens buttons: 0.5×, 1×, 2× and telephoto where available. • Flash, torch for video, 3 and 10 second timer, grid. • 3:4, 9:16 and 1:1 frames. • White balance: auto or daylight, cloudy, tungsten and fluorescent presets. • Take pictures with the volume buttons or Camera Control. TELEPROMPTER • Keep your scripts in a built-in library: write, paste, edit. • While you record, the text scrolls right under the front camera, so you look almost straight into the lens. • Change speed and text size on the fly. The teleprompter never appears in the video. YOUR LOGO ON EVERY VIDEO • Add a logo from Photos or Files; a transparent PNG stays transparent. • Nine preset positions or drag it anywhere, then set its size and opacity. • Turn it on once and it appears on every video, and on photos too if you like. PHOTO AND VIDEO • HEIF or JPEG photos at full camera resolution. • HEVC or H.264 video with sound. • What you capture matches what you saw on screen. • Optionally keep both original shots as well. PRIVACY Dual Lens collects no data at all: no accounts, no analytics, no ads. Your captures go only to your Photos library. Requires an iPhone with iOS 26 or later.
