Safelight Darkroom Timer vs FilmDev

Safelight Darkroom Timer helps analog darkroom printers calculate exposure changes, run timed print workflows, and save the setup that worked. Use the darkroom-friendly timer for Focus, Expose, and Process timing with large controls, red/amber/green display themes, optional haptic feedback, completion sound, and keep-screen-on behavior when enabled. Turn one base exposure time into a stop-based table with the F-Stop Calculator. Use free 1/4 and 1/3 stop steps, send a result to the timer, or run a test strip one exposure at a time. Save print sessions with base exposure, stop step, paper, filter grade, developer, and notes so you can repeat or adjust your best darkroom prints later. Search, edit, delete, repeat, and use saved sessions from the Sessions screen. Use the Print Process Timer for expose, develop print, stop bath, fix, and optional wash steps. Manage darkroom metadata presets for paper, developer, and filter grades. Safelight Pro unlocks unlimited saved sessions, advanced stop steps, Dodge & Burn planning, memory banks, run plans, and CSV/Text export and sharing. Important: Safelight is a darkroom-friendly display and timing utility. It is not a flashlight, photo editor, AI app, lab ordering service, hardware enlarger controller, or guarantee that a phone screen is safe for every photographic paper or film. Always test your own paper and darkroom conditions.

FilmDev is a darkroom-safe multi-stage timer built for home film developers — B&W and C-41, push/pull, and beyond. ■ Multi-stage auto-advance timer Set up develop, stop, fix and wash stages once. FilmDev counts each stage down and auto-advances to the next — no fumbling for a stopwatch in the dark. ■ True darkroom-safe screen Running timer screen is pure black with a deep red display only — no white pixels, no accidental flash. Fullscreen immersive, safe for your eyes and your film. ■ Haptic + beep agitation cues Feel and hear when it's time to agitate — configurable haptic pulses and beep cues so you don't need to watch the screen. ■ Wall-clock accurate, even backgrounded Timing is based on real elapsed time, not a fragile in-app counter — lock your phone or switch apps and the timer stays accurate when you come back. ■ Temperature compensation Adjust develop time for your actual chemistry temperature using a standard B&W time-temp factor. A guide, not a guarantee — always verify against your own testing. ■ Your own recipe library Build and save your own recipes — film stock, developer, dilution, temperature, and every stage. Starter recipes are included from manufacturer datasheets, clearly marked "verify before use." Your recipes, your times. ■ Develop log Log every roll you develop — recipe used, film, developer, notes and a rating — so you can track what worked. ■ FilmDev Pro (one-time purchase) Unlock unlimited recipes, remove ads, and export/import your recipe library as JSON. One-time purchase, no subscription. ■ 8 languages, private by design No account, no cloud. Everything — recipes and logs — stays on your device.
