Latest upgrade broke on iPhone 4S


I’ve been using this app for quite some time, and must say it is very useful when I develop black and white film, and I rather like it. However the latest upgrade broke on my iPhone 4S despite the fact that the phone is running iOS 9.3.5, which the app is supposed to run on. The problem is that UI elements tend to overlap on the screen, making some parameters impossible to change. (Example: trying to turn on time-temperature conversions changes the temperature setting! I tried using a stylus instead of my finger but it didn’t do any good.) The app works fine on my iPhone 6S+, but as that is my primary phone I’d rather not expose it to chemicals - that’s what I use the old 4S for. Guess I won’t have a choice until the problem is fixed in a future update.

Could I make another suggestion? Please allow different agitation regimens for developing and fixing.

The best!!


I’ve been using this app for years. This is THE BEST app out there if you’re going to be working in the darkroom. Couldn’t recommend this app more.

Black and white only


No where does it state its black and white only. Completely useless to me.
