Film Developer Pro

★★★★★ Could do with clear instructions as not all film and developer combinations will calculate a developing time for you and allow you to start the timer. In these instances you should look up the massive Dev chart online and enter the dev time manually on this app. Otherwise, the app seems to work well.

★★★★★ The app is reliable with well known films and developers... with more niche films it's a bit of trial and error.

★★☆☆☆ Great functionality, horrible usability. The data and functions in the app are great and what one would want and like. But the usability makes it impossible to use. Every time I made a mistake I had to completely exit the app and restart what you were doing.

★★☆☆☆ Used this to develop a roll of 120 Ilford hp5 plus on d-76, and it came out way over exposed. I thought it was my mistake with a new type of film, but then I checked the development times for tri-x on the same developer, and it was 1 minute and 15 seconds longer than Kodak suggests, they say 5:30, this app says 7:45, you can check it yourself, at 24°. So, essentially the one thing that this app is meant to do, it doesn't. I'm sad that my images were so over exposed as to be essentially unusable.
