2Camera+ vs Duoptra

2Camera+ is a dual-camera app for creators and everyday storytellers. Capture the front and rear cameras at the same time, combine them in picture-in-picture or split layouts, and put “what you see” and “your reaction” in one frame — less post-production stitching. Highlights - Dual live preview: On iPhones that support concurrent multi-camera (MultiCam), preview front and rear at once; unsupported devices show a message and fall back to single-camera mode. - Picture-in-picture (PiP): One main and one overlay feed by default; drag the overlay, pinch to resize, double-tap or use controls to swap main and secondary. - Split layouts: Side-by-side or stacked splits — switch layouts to match your shot. - Overlay shapes: Multiple mask styles (e.g. rounded rect, circle, star) to style the secondary view. - Synced still capture: Capture both cameras and output a composite (format and resolution depend on device and system). - Synced recording: One composite video file (typically HEVC or similar, per device and settings) for easy sharing and editing. - Save to Photos: Save composites to the library when write access is granted; if denied, behavior follows sandbox limits and in-app messaging. - Orientation: Preview and output follow device orientation where possible for a consistent WYSIWYG experience. - Dark Mode: UI follows system light/dark appearance. - Localization: Interface strings follow system language where available (exact languages depend on the build and App Store locale settings). - Teleprompter (optional): overlay notes, editing and scrolling; prompt text is not burned into exported photos or videos. - Single-camera capture: Settings switch to one camera for lower power; single-file still or video output. - Preview framing: full-screen or 16:9 / 4:3 / 1:1 style ratios aligned to screen long edge. Ideal for vlogs (presenter + subject), online teaching, events, and any shot that needs two angles on one screen. Full dual-camera capability requires hardware and OS support for multi-camera capture — try on a real device for the best experience.
