Halcyon Camera vs DuoShot

Halcyon brings the soul of film to your iPhone. Twelve hand-crafted film stocks — Kodak Portra 400, Cinestill 800T, Velvia 50, Tri-X 400 and more — each with the temperature, tone curve, grain, and halation of the real thing. Apply them live, before you take the shot, and what you see is exactly what you get. REAL PRO CONTROLS, ONE-HANDED. Full manual ISO, shutter, focus, white balance, and exposure. Tap to focus.

Record what you see—and yourself—at the same time. DuoShot captures the front and back cameras together for photos, picture-in-picture videos, and clean camera views for screen recording or live streaming. Show the scene and your reaction in one frame. CLEAN LIVE MODE Enter Live Mode from Settings to hide controls and watermarks while keeping both camera views visible and the screen awake. Start screen recording or broadcasting through the system or your preferred streaming app. Press and hold the main camera view for one second to exit. FRONT + BACK AT THE SAME TIME Capture the scene and your genuine reaction in a single recording. MOVABLE PICTURE-IN-PICTURE Move the PiP window to suit your scene and keep both the action and your reaction in view. DUAL-CAMERA PHOTOS AND FACE EFFECTS Save both perspectives in a single photo, or add playful effects to the front camera. DATE, TIME, AND LOCATION WATERMARKS Add context to travel, local discoveries, and everyday moments with optional watermarks. Clean Live Mode hides them automatically. UP TO 4K, 60 FPS Choose resolutions from 720p to 4K and record at 24, 30, or 60 fps. Select a lower resolution for longer sessions to reduce image-processing load. Available options depend on your device and system conditions. PORTRAIT AND LANDSCAPE Perfect for vlogs, travel, concerts, tutorials, product demos, family moments, and reaction videos. SAVE DIRECTLY TO PHOTOS Your finished video is saved automatically—no exporting workflow or complicated setup. PRIVATE BY DESIGN No account required. Capture and image processing happen locally on your device. DuoShot does not upload your photos or videos. Dual-camera recording requires a device that supports simultaneous multi-camera capture. Available resolutions and frame rates depend on device hardware and system conditions. Clean Live Mode provides camera views, without a built-in streaming service. Start screen recording or broadcasting through the system or another app.
