DevGlass
iOS Universel / Photo et vidéo
DevGlass is a professional B&W film development reference and processing timer designed for analog photographers. Whether you're developing your first roll or your thousandth, DevGlass puts everything you need at your fingertips — no internet required.
DEVELOPMENT CHART Browse a comprehensive database of 308 films, 190 developers, and 11,849 development recipes. Filter by film format (35mm, 120, Sheet), select your film and ISO, then find the exact development time and dilution you need. Push and pull processing times are included for most combinations.
MULTI-STEP TIMER Start a complete development session with a single tap. The timer guides you through every step — pre-soak, developer, stop bath, fixer, hypo clear, wash, and photo-flo. Each step can be enabled, disabled, or adjusted to match your workflow. Sound alerts and haptic feedback keep you on track, even when your phone is face down.
AGITATION REMINDERS Choose from standard, continuous, minimal, or custom agitation schemes. DevGlass reminds you when to agitate with audio and haptic alerts so you can focus on your process, not the clock.
TEMPERATURE COMPENSATION Working at a temperature other than the recipe standard? DevGlass uses the Ilford compensation formula to calculate the adjusted development time automatically.
DILUTION CALCULATOR Quickly calculate how much concentrate and water you need. Select from common tank presets (Paterson, Jobo, AP Compact) or enter a custom volume. Supports all standard dilution ratios.
FAVORITES & SESSION LOG Save your go-to recipes for instant access. Log every development session with film, developer, time, temperature, and your own rating and notes — build a personal darkroom reference over time.
TANK GUIDE A handy reference for popular developing tanks, including capacity, compatible film formats, and agitation methods.
DESIGNED FOR THE DARKROOM DevGlass features a vintage print-inspired interface that's easy to read and pleasant to use. Bilingual support (English and Simplified Chinese). All data is stored locally on your device — no account, no cloud, no tracking.
