ColorDev Timer vs Grain Film Toolkit

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.

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.
