ReelDuo: Dual Camera Recorder is a free-to-use iPhone camera app by developer Jaspal Singh that records both front and rear cameras at once and automatically saves every take in vertical 9:16 and horizontal 16:9 files, ready to post without editing.
What is ReelDuo: Dual Camera Recorder?
ReelDuo is an iOS photo & video app designed to eliminate the need to film the same content twice for different social platforms. It captures video from both the front and back cameras simultaneously (Duo mode) and also offers a single-camera Solo mode. For each recording, the app exports synchronized 9:16 (portrait) and 16:9 (landscape) videos to the Apple Photos library, with Pro features adding higher resolutions and extra formats.
Key Features
- Dual-camera recording — Record front and back cameras together in a picture-in-picture layout that you can drag and resize freely.
- One take, every format — Every recording saves a vertical 9:16 file for TikTok, Instagram Reels, and YouTube Shorts plus a horizontal 16:9 file for YouTube, automatically synced.
- Pro capture controls — Up to 4K at 60fps in Pro mode, video stabilization, HEVC encoding, tap-to-focus, AE/AF lock, pinch-to-zoom, exposure control, and a rule-of-thirds grid.
- Live crop guides — Overlays show exactly what the vertical and horizontal versions will capture so you can frame both simultaneously.
- Solo mode with wide landscape — Shoot with one camera and enable “Wide landscape” to capture the full sensor width in true 16:9, not a cropped version.
- Self-timer — Choose a 3, 5, or 10-second delay in both Solo and Duo modes.
- VoiceOver and Siri — Full accessibility support across focus, exposure, zoom, and PiP; also works with “Hey Siri, start recording in ReelDuo.”
- Localized — The entire app and permission prompts are available in English, French, German, Hindi, Japanese, Korean, Portuguese, and Spanish.
Who is it for?
ReelDuo is built for any creator who needs different video orientations without extra editing work.
- Social media creators — People who publish to TikTok, Instagram, and YouTube Shorts can get portrait videos ready immediately while also having a landscape version for other platforms.
- Influencers and YouTubers — Those who repost content across accounts save time by not shooting the same footage twice; a reviewer noted it’s “perfect for creating content in portrait and landscape in one go.”
- Vloggers and reaction channels — Front-and-back recording lets you show your face and the subject simultaneously, with the PiP position adjustable.
- Everyday iPhone users — If you want a quick way to record a moment in multiple formats or try a new angle, the clean full-screen camera has no learning curve.
What can you do with ReelDuo?
- Content creators: Film a reaction or commentary with the front-facing camera while the rear camera records the product or scene, then post the 9:16 version to Stories and the 16:9 to YouTube without re-recording.
- YouTubers: Use Solo mode with “Wide landscape” to capture a true 16:9 video using the full sensor width for long-form horizontal content.
- Pro users: After purchasing the Creator Pack, a Duo take can also save front and rear camera tracks as separate files, allowing you to re-edit either angle later, and Solo takes can additionally export 1:1 and 4:5 versions.
How does ReelDuo work?
The app presents a full-screen camera interface with controls for Solo/Duo mode, resolution, frame rate, and self-timer. In Duo mode, both cameras start recording at the same time, and when you stop, ReelDuo automatically writes the synchronized 9:16 and 16:9 files to your Photo library. The app’s resolution and frame rate selections are remembered between sessions, and recording can be started or stopped via Siri.
Pricing
ReelDuo is free to download and use for dual-format recording and front+back multicam reactions. A one-time in-app purchase named ReelDuo Pro (₹299 in the Indian App Store, with no subscription) removes the watermark, adds 4K at 60fps, and unlocks Creator Pack features like separate audio/video file exports and extra aspect ratios. No account or sign-in is required.
Alternatives
Other dual-camera apps available on the App Store include Double Camera Record – DuoCam, Dual Camera: Front & Back Cam, ContentCam: Dual Camera Video, and Double Camera Take. ReelDuo stands out by generating both 9:16 and 16:9 from every take natively, while some rivals may require post-production cropping.
