DevClock is a focused darkroom companion for black-and-white film work. Build quick timers, follow film development steps, and keep your process readable in low light. DevClock is designed for practical darkroom use: large controls, high-contrast timing screens, red mode, local notifications, haptics, and Live Activities for supported iOS devices. Key features: • Quick Timer for simple countdowns • Film and developer setup for black-and-white workflows • Guided process timing for develop, stop, fix, and wash steps • Red mode for darkroom-friendly viewing • Local notifications and haptic reminders • Live Activities for timer status on supported devices • Custom process plans • English, Simplified Chinese, Traditional Chinese, and Japanese interface options Important note: built-in development times are intended as useful starting points, not guaranteed processing instructions.
