Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

grain. is a toolkit built for film photographers who want to work with intention. EXPOSURE CALCULATOR Use the Sunny 16 rule to calculate the correct aperture for any lighting condition. Enter your film ISO and shutter speed — grain. gives you the aperture instantly. Enable Reciprocity Correction for long exposures and let the app compensate for your film's reciprocity failure automatically. FILM ROLL TRACKER Log every roll you shoot. Track film stock, camera body, ISO, and frame count. Update each roll's status from Loaded to Exposed to Developed. Never lose track of what's in your camera or what's waiting to be developed. DARKROOM TIMER Choose a built-in development preset or build your own custom pipeline. The timer walks you through each step — developer, stop bath, fixer, wash — and alerts you when it's time to move on. Safelight Mode switches to a red-safe display so you can work in the dark without fogging your prints. LIGHT METER A built-in incident light meter using your iPhone camera to help you read the light before you shoot. Your photos are saved only on your device. grain. never uploads, shares, or stores your images anywhere.
