Description
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. Long-press for AE/AF lock. Pinch to zoom. Volume buttons fire the shutter. Lens switcher for ultrawide, wide, telephoto. Halide-style focus loupe magnifies the sharpness plane as you rack focus. Histogram, waveform, focus peaking, zebras, false color, horizon level — when you need them, hidden when you don't. NEW IN 3.2 — LONG EXPOSURE, SLOW-MO, LIVE PHOTO. • Multi-frame long exposure — 2, 5, 10, or 20 second stacks with automatic alignment for handheld light trails, silky water, and star fields • Slow-motion capture at 120fps and 240fps • Live Photo for every film stock — the frames before and after, with the film baked in • Thermal and storage health warnings before a long take can bite you • Alternate app icons: Amber, Midnight, Noir BUILT-IN PRO OVERLAYS. • Histogram — real-time RGB • Waveform — luminance monitor • Focus peaking — see what's sharp • Focus loupe — Halide-style magnifier • Zebras — highlight clipping alert • False color — exposure map • Horizon level — stop crooked photos • Rule-of-thirds grid • Cinematic frame modes — square, 3:2, 16:9, half-frame • Live ISO / shutter chips PRO VIDEO WITH FILM SIMULATION.

WYSIWYG: every effect — film, grain, halation — is baked into the saved photo. ProRAW is preserved as alternate. Create custom film recipes with a 14-slider editor. Save them, share them, refine them. YOUR PHOTOS STAY ON YOUR DEVICE. No analytics. No data collection. No network requests. Nothing leaves your iPhone. Made with care for everyone who misses film.
