ColorDev Timer vs Grainium

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.
