What's New in Develop! Film Timer

4.0

November 12, 2026

Develop! is back, rebuilt for today's iPhones. FIXED: NO MORE CRASH WHEN MUSIC IS PLAYING If Develop! ever quit on you at the end of a task while you had music on, that's fixed. Your music, podcast or audiobook now dips under each beep and comes back, whatever app it's playing in. NEW - The timer keeps running when you leave the app or lock your phone, with a notification when a task ends and at every agitation chime. - Tasks and intervals can now be up to 90 minutes. - All-new Voice Control: faster, more accurate, and it works without an internet connection. Say NEXT, OK, BACK, CANCEL or RESTART. - A new timer look, styled after a classic camera body. - Darkroom Mode is now strictly red on black, everywhere in the app. - Share recipes as files through Mail, Messages, AirDrop and more. GOOD TO KNOW - Beeps now sound even when your phone is on silent, so you won't miss the end of a task. - Old flm.to recipe links no longer work. Ask the sender to share the recipe file instead. - With Voice Control on, your music pauses when a task ends so the app can hear you, and picks up again when the next task starts.

Perfect

Simple, useful and user friendly. Great little app. Surprised itโ€™s free to be honest. Interface is clean and uncluttered and you can fine tune the steps you need to Top marks for this one.

Fabulous!

Simple, awesome, and free. Genius. THANK YOU!!!

Great tool

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

This is what you are looking for.

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.

Does exactly what is needed. Thank you!

The app is economical, efficient, to the point and simple to negotiate. Rarely does that happen. Definitely a go to when I am developing film.
