Develop your film with a smile! Develop! is a flexible, elegant timer for developing film and working in the darkroom. Build your own development recipes in a few taps: as many steps as you need, each with its own agitation intervals. It's entirely up to you; you're in full control. Notable features: - Voice Control: Hands wet? Just say "NEXT" to move on to the next step. Recognition runs on your iPhone, no internet connection needed. - Keeps time in the background: Leave the app or lock your phone and the timer keeps running. You'll get a notification when a step ends and at every agitation. - Intervals: A built-in interval timer handles things like "beep after the first minute, then every 30 seconds." You'll see at a glance how long until your next inversion. - Darkroom Mode: A strict red-on-black theme for darkroom use. - Flexible: As many recipes and steps as you like, steps of up to 90 minutes, named your way, with notes for every recipe. - Easy to read: A large timer you can see across the room, styled after a classic camera body, right down to the vulcanite. - Import: Bring in recipes straight from FilmDev.org. - Share: Send a recipe as a file with Mail, Messages, AirDrop or anything else on the share sheet. No more losing track of time or forgetting to agitate every 30 seconds. Concentrate on being the best photographer and alchemist you can be, and leave the timing to Develop! Now go out there and shoot a roll of film. Good luck! 100% free. Always.
