FlexiDual is a multi-camera recording app for iPhone creators who need useful files from one take, not just one baked-in clip. Choose the capture mode that fits the shoot: โ€ข Front + rear dual camera: record yourself and the scene together, then save front, rear, and Program videos. โ€ข Dual-rear dual-format: capture portrait 9:16 and landscape 16:9 deliverables from rear cameras. โ€ข Single-lens dual-format: turn one rear camera into portrait and landscape outputs. โ€ข Single-camera: record locally or publish a live stream. Frame with split screen or PiP, adjust layouts while shooting, and use zoom, focus, exposure, filters, custom .cube LUTs, portrait enhancement, teleprompter, smart framing, composition guides, safe-area guides, level guide, zebra, focus peaking, and preview monitoring metrics. Your sessions stay local by default. Browse recordings in the library, save to Photos, retry failed saves, delete sessions, and create Program variants for delivery presets. Live broadcasting supports RTMP, RTMPS, and SRT. Still photo capture supports normal photos and ProRAW capture on supported devices. Dual-camera, dual-rear, ProRAW, 4K/60fps, professional codecs, and live streaming availability depend on iPhone model, iOS version, thermal state, storage, and connected targets.

About

One Big Camera

Read full description

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.
