About

Islet

Features
Read full description

Islet turns your iPhone into a retro instant camera — and your Dynamic Island into the slot the photo prints from. Frame your shot, press the big red shutter, and watch a polaroid slide out of the top of your screen, develop, and drop into your gallery. It's the unmistakable ritual of instant film, rebuilt natively for iPhone. FILM LOOKS, DONE RIGHT • Ten hand-tuned looks inspired by real stocks — Kodak Gold, Portra, Fuji, Velvia, Polaroid 600, mono, sepia and more. • A GPU film engine (Metal) adds true split-toning, tone curves and grain — not a flat overlay. • Dial any look up or down with an intensity slider, and your favourites so they're always first. • VSCO-grade grain, light leaks and a warm vignette — toggle them per shot. A REAL CAMERA UNDERNEATH • Tap to focus, drag for exposure, pinch through every lens your iPhone has (0.5× / 1× / tele). • Front and back cameras, true flash, and a self-timer. • Long-exposure mode for silky motion and light trails. • 4-up photobooth mode for a classic strip. • Aspect ratios and frame styles: classic white, cream, black border, Instax. KEEPSAKES, NOT JUST FILES • Every print lands in a tactile gallery you can flip through. • Attach a voice memo to a photo — the sound of the moment. • "On this day" memories resurface old shots. • A home-screen widget shows your latest print. PRIVATE BY DESIGN • No account. No ads. No tracking. No network. • Your photos stay on your device unless you choose to Save or Share them. Islet is GEN 1. Load some film and start shooting.
