DuoRec: Dual Camera

DuoRec is the dual camera Android app designed to record what you see and your reaction at the exact same time. Capture both the front and back cameras simultaneously into a single synchronized video file, instantly ready to share.

Two cameras. One story.
Life isn't just about what is happening—it is about how you experience it. DuoRec lets you capture both sides of every moment:
• Travel and concerts: Capture the view and your emotions without flipping your phone.
• Celebrations and surprises: Record the gift opening and their reaction simultaneously.
• Video reactions: Select a video from your gallery and record yourself reacting to it live.

Key features:
• Simultaneous dual recording & photography: Front and rear cameras composed in real time.
• Zero editing needed: Videos are merged on the fly. When you stop recording, it’s already saved in your gallery.
• Flexible layouts: Choose between floating window (Picture-in-Picture) and split-screen mode.
• Live face filters: Apply fun real-time facial filters and effects while recording.
• Record at your pace: Pause and resume whenever you want.
• Full 4K quality: Record in the highest resolution supported by your phone’s camera hardware.

100% Private and Offline:
• No accounts or sign-ups: Open the app and start recording right away.
• No cloud or servers: All processing is done locally on your phone.
• No tracking or ads: Zero trackers and clean experience.

Hardware requirements:
Simultaneous dual camera recording requires Android devices with Dual ISP processors and native support for Android Camera2 Concurrent Streaming API.
