iPhone
Develop film at home with confidence: precise step timers, agitation alerts that reach your pocket, temperature-adjusted times. Your darkroom, your log, no account.
Banho is a timer built for the darkroom. Pick your process, check the steps and start. Every second counts, and Banho keeps count for you, even with the screen locked.
THREE PROCESSES, REFERENCE TIMES
Black and white, C-41 color negative and E-6 slide film, with step-by-step times from the Ilford and Kodak reference documentation. For black and white, enter your measured temperature and Banho adjusts the developer time.
ALERTS THAT REACH YOU
Agitation reminders and step changes arrive with sound and vibration, on the lock screen and the Dynamic Island. Keep both hands on the tank.

Build your own recipes: film, developer, dilution, steps, times, agitation. Saved on your device. No account, no sign-in, no cloud.
