ColorDev Timer vs DarkroomLog

ColorDev Timer is designed for analog photographers developing color film (C-41) who want a clear, reliable, and distraction-free workflow. Choose your development kit, enter the total chemistry volume, how many rolls have already been processed, and whether you’re pushing or pulling film. The app calculates the timings and guides you through each development phase with a clear, lab-friendly timer. All development phases are listed with their individual durations, and the current phase is clearly highlighted. You can start any phase with a single tap and reset the entire process whenever needed. ColorDev Timer also tracks chemical usage, helping you know when your chemistry is approaching its recommended limits. Key features: • Phase-based development timer • Push / pull support • Development kit and volume selection • Roll usage tracking • Clean interface suitable for darkroom use • Designed for real analog workflows • App for Apple Watch No ads. No accounts. No clutter. Just analog photography.

DarkroomLog is a session logger, film catalog, and chemistry tracker for analog darkroom photographers. Log every printing session with equipment details, exposure steps, and notes. Attach a photo of each print for your reference archive. Rate your best prints with up to three stars. SHARE YOUR WORK Generate a beautifully designed dark card for any print or film roll and share it directly to Instagram, Mastodon, or anywhere else. Print cards include the photo, name, rating, film roll, enlarger, lens, paper, developer, and exposure settings. Choose portrait or landscape layout before sharing. Film roll cards show the full development record: film stock, developer, camera, lens, notes, and print count. LIGHT TABLE Browse and catalog your film rolls in a dedicated tab. Record format (135 or 120), film stock, camera, lens, developer, and notes for every roll. Link rolls to individual prints to keep your workflow connected from film to paper. CHEMISTRY TRACKER Track every chemical batch you mix — developer, fixer, bleach, stabilizer, stop bath, or anything your process requires. Log the mixed date, capacity in rolls, and shelf life. Add a roll manually as you work, just like marking a tally on the bottle. A color-coded progress bar shows how exhausted or close to expiry each batch is at a glance. Search by name or notes. Works for any process — black-and-white, C-41, ECN-2, or alternative. DARKROOM TIMER The built-in timer counts seconds with an audible metronome tick. Shake, toss, or tap to restart. The screen dims automatically during exposure. Set multiple timed steps per print — each step signals with a bell when complete. FILM DEVELOPMENT TIMER A separate timer for outside the darkroom — white digits, normal brightness. Use it for development, stop bath, or fixing. Same shake and knock controls. A bell rings every minute as a reminder. WASH TIMER Start a background wash timer directly from a print. When the time is up, you receive a notification — even if the app is closed. Perfect for fiber-base paper that requires extended washing. EQUIPMENT LIBRARY Build a reference library of enlargers, lenses, papers, developers, cameras, and film stocks. Browse by category and select equipment quickly when logging a session or a roll. BACKUP & RESTORE Export all your sessions, prints, film rolls, equipment, and chemistry batches as a single JSON file. Restore on any device at any time. SETTINGS Toggle the metronome on or off. Switch to a dark interface regardless of system appearance. No account required. No ads. No tracking. All data stays on your device.
