Film Development Timer

Features & Capabilities

Develop! is a flexible, elegant timer designed for film development and darkroom workflows. Build development recipes with as many steps as you want, each with multiple intervals, and name steps freely. The large timer sits prominently on screen so you stay on track.

Darkroom Mode delivers a red-on-black interface, while interval beeps and notes help you time pours and agitations. Import recipes from FilmDev.org, and share your creations with the community. Best of all, it's free—let your photography shine while the timer handles the timing.

I use this frequently for storing and using development recipes for a wide range of film. I’ve been using it for a few years now with no issues.

This is the app you are looking for. It has exactly what you need to time your development, nothing more, nothing less. If j could request one feature, it would be the option to add 2% to a previously used setting. For re-use of chemicals. But I can do that manually for now.
