Reaction shots that need no editing
Opening a package, hearing a result, tasting something. The thing and your face land in the same frame, in the same file, at the same second — nothing to line up in a timeline later.
iPhone · Free · No account
Film what you see and your face reacting to it — in one take.
DualCam runs the front and back cameras at the same time and merges both into a single MP4 while you shoot. No editing app, no stitching afterwards, no second phone.
Free. No in-app purchases, no ads, no sign-up.
Requires iPhone XS or newer — dual-camera recording is a hardware feature and older iPhones cannot do it.
What people actually shoot with it
Vlogs where you narrate the view
Walk through a street, point the back camera at it, and stay in the corner talking. Your commentary and what you are pointing at are never out of sync.
Tutorials and interviews
Show your hands doing the thing while your face explains it. Or record both sides of a conversation on one phone, laid out side by side.
Driving, riding, courtside
Road ahead in the big frame, you in the small one. One phone on a mount, one file at the end.
Three layouts, changeable mid-recording
Switch layout while the camera is rolling — the recorded file follows the change instantly, because the preview and the recording are literally the same rendered frame.
Picture-in-picture
One camera fills the frame, the other floats in a corner. Drag the small window to any of the four corners, pick three sizes, and choose its shape: portrait, square or circle.
Split — top and bottom
Both cameras get half the height. Best when both sides matter equally.
Split — left and right
Both cameras side by side. Note that a vertical canvas has to crop about 25% from each side of the source frames, so keep faces centred.
Canvas is 1080 px wide, in 9:16 (1080×1920) or full screen (1080×2340) — the second one fills a modern iPhone display edge to edge.
Camera controls, where you can reach them
Pinch to zoom, tap to focus
Tap the frame you want sharp. Exposure compensation is on the same control.
Lens picker
Ultra wide, wide or telephoto on the back camera, depending on what your iPhone has.
Six live filters
None, Vivid, Warm, Cool, Mono and Film — applied in the shader as you record, not afterwards.
Countdown timer
Off, 3, 5 or 10 seconds, so you can get into frame before it starts.
720p or 1080p
Both cameras at once is heavy. 1080p is there, with an honest warning that some devices will throttle.
Torch, grid, mute
Flashlight, composition grid, and a silent mode that records without an audio track.
Built-in recording library
Every take is kept inside the app, with thumbnails. Save to Photos or share when you decide to — not automatically.
It survives real life
Incoming calls, another app grabbing the camera, overheating, a full disk — each one stops and closes the file properly instead of leaving you a corrupt video.
Your footage never leaves the phone
There is no server in this product. Nothing is uploaded, nothing is analysed, there is no account to create and no analytics to opt out of.
- No account, no email, no sign-up.
- No ads, no trackers, no third-party SDKs.
- Recordings stay in the app's own folder until you save or share them yourself.
Device requirements
Recording two cameras simultaneously is done by the iPhone's capture hardware, not by software, so it has a hard floor:
- iPhone XS, iPhone XR or newer.
- iOS 17 or later.
- iPhone, portrait orientation. Not available on iPad or on the Simulator.
On an unsupported iPhone the app tells you so on launch instead of pretending.
Questions
Does it really record both cameras at the same time?
Yes. The two camera streams are composited into one frame in real time on the GPU, and that exact frame is what gets written to the video file. What you see in the preview is the recording.
Why does it need an iPhone XS or newer?
Simultaneous front and back capture uses AVCaptureMultiCamSession, which Apple only supports on A12 chips and later. It is not something an app can work around.
Do I get one video file or two?
One. A single MP4 with both cameras already laid out, ready to post.
Is it free? Is there a subscription?
It is free, with no in-app purchases and no ads in this version.
Can I change the layout while recording?
Yes — layout, picture-in-picture corner, size, shape and filter can all be changed mid-take. Resolution, mute and the countdown are locked once recording starts.
Can I record silently?
Yes, mute records without an audio track. Because the track is created when recording starts, mute has to be set before you hit record.
