Darkroom Timer / Film Developing Timer

Ratings and reviews

Works perfectly well for me. All the films and my go to developer are in the database, times and calculations have worked out perfectly well. The added liquid mixing calculator is super helpful if too lazy to do it myself. Yes, you have to get used to some of the interface, but after a quick period of getting familiar with everything I have no problems with setting up my process and can quickly go from black and white to colour chemistry. Overall does exactly what I hoped it would do.

OK app but overly complicated and confusing interface. I don't understand the point of the archive function. There should be a simple way to save your custom settings/process to the archive. In general the interface could be simpler and more intuitive. Plus there are a few bugs when you add steps. Sometimes they don't show up. But if you do it again it says entry already exists.

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.
