Record both iPhone cameras at the same time. CamDuo captures your front and back cameras in a single take — your face and your scene, one video, no editing tricks.
RECORD WITH BOTH CAMERAS
• True simultaneous capture from the front and back cameras
• Live picture-in-picture preview while you shoot, so you always know what you're getting
• Torch control right on the record screen for low-light shots
• A 3 or 10 second countdown so you can get yourself into the frame first
• Optional rule-of-thirds grid for straighter, better-composed shots
• Haptic feedback when recording starts, stops, and saves
STUDIO — COMBINE ANY TWO VIDEOS
• Pick two clips from your CamDuo recordings or from your Photos library
• Three layouts: Picture-in-Picture, Side by Side, and Top and Bottom
• Move the picture-in-picture overlay to any corner you like
• Swap which video is fullscreen and which is the overlay with one tap
• Studio opens with your latest recording already loaded
• Live preview of the finished composition before you export
SAVE AND SHARE
• One-tap export to Photos in 1080p with synced audio
• Your recordings list shows a real frame from each video, not a generic icon
• Vertical and ready for whichever feed you post to
PRIVATE BY DESIGN
Every recording stays on your device. No account, no sign-up, no uploads. We don't run a server, so your videos never touch one. The only network calls CamDuo makes are for purchase verification and ads — both anonymous.
UNLOCK EVERYTHING — ONE PAYMENT, NO SUBSCRIPTION
CamDuo is free to use. Free recordings are capped at 3 minutes, a short rewarded ad plays before saving, and exports carry a small CamDuo watermark.
A single purchase removes all of that, for good:
• Unlimited recording length
• No ads, ever
• No watermark on exports
• One payment — no subscription, no renewal, yours for life
WHO CAMDUO IS FOR
• Creators filming their reaction to whatever is on screen
• Vloggers and travelers who want to be in the shot, not only behind it
• Coaches, teachers, and instructors recording a demonstration and their commentary at once
• Anyone who has ever wished their phone could look in two directions
REQUIREMENTS
• iPhone XR or later — simultaneous multi-camera capture is a hardware requirement, and CamDuo tells you clearly if your device can't do it
• iOS 16 or later
• Camera and microphone access
