Simul Studio vs Analog Roll

Simul turns your iPhone into a film camera and a darkroom. Shoot through real film-inspired looks and see the result live, or bring in photos you already have — the grain, the tones, the character of film, in seconds instead of weeks. 544 FILM-INSPIRED PRESETS Browse a huge library of looks modeled on classic analog stocks — warm consumer negatives, punchy slides, moody black & white, and more. Tap to preview, swipe to compare before and after. A DARKROOM IN YOUR POCKET • Film grain and halation with fine manual control • HSL color mixer, tone curves and split toning • Exposure, contrast, highlights, shadows, clarity, vibrance • Local radial & linear masks to dodge and burn • Crop, straighten and one-tap auto-align • Film frames & borders — white, black, 35mm sprockets with rebate text, and Polaroid • Optional retro date stamp SHOOT A ROLL Load a virtual roll of 24 or 36, pick your film, and shoot blind — no chimping, no deleting. When you're ready, develop the roll and watch each frame come to life, negative to positive. The anticipation of film, without the lab.

Analog Roll isn't an Instagram filter. It's a real roll-film camera, with all the friction and surprise of shooting on film — right on your phone. HOW IT WORKS Pick a roll (24 or 36 shots), shoot, and that's it: the photo gets locked. You won't see it until it "develops" — you decide if that takes 1 minute, 12 hours, 24 hours, or 30 days, like mailing it off to be developed. No preview, no retouching, no second chances. That's how real film gets shot. REAL EMULATION, NOT A FILTER Every photo runs through real 3D LUTs, scanned grain, and the same color curves as a good physical roll — not a semi-transparent layer slapped on top. The result doesn't look like a filter: it looks like a roll of film. 5 ROLLS • Amber 200 — vivid colors, warm tones • Super 400 — bright greens, clean blues • Noir Ultra 400 — black and white, classic soul • Retro Dusk 800T — cinematic nights, halation in the highlights • Analog Roll — the free starter roll: every shot uses a different film stock, at random. You never know what you'll get. DOUBLE EXPOSURE Stack two shots on the same frame, like not advancing the roll between takes. Real, not an editing effect. PRIVATE BY DESIGN Your rolls and photos are 100% local — they never leave your phone unless you decide to post a photo that's already developed. No cloud, no mandatory account, no auto-upload. FRIENDS (OPTIONAL) If you want, connect an account and add friends by scanning a QR code. Post your developed photos — they're visible instantly and disappear after 24 hours, like a polaroid passed from hand to hand. Analog Roll is for anyone who misses the wait. For anyone who'd rather have 36 intentional shots than 3,000 photos never looked at. Load a roll and shoot.
