Darkroom Timer / Film Developing Timer

Ratings and reviews

Good app, overall. The flexibility to create a fully customized chain of steps is fantastic. One request would be to have it pop up a message that it can't find a valid time for a given combination of developer + film. As it is, the app sits there, showing you a blank timer, and refusing to allow you to save as a favorite, with no explanation. Worse, if you rearrange the process to add a pre-soak step before the main timer (which is great that you can!), then the developer timer crashes out leaving you staring at a useless screen while trying to remember how many seconds it's been, and trying desperately to sync up to a digital clock nearby while you switch over to a stopwatch app and try to get it sync'd to the nearest 30 seconds. So a validation check on each step of the process would be helpful. :)

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.

User Interface is a bit clunky and not that intuitive but the app does a good job once you get used to it. A button to reset all search-parameters at once - like developer/ ASA / agitation rhythm etc. - would be nice. Right now you have to reset every value yourself, because the grey checkmarks only help if you type in the parameters in a specific order. A simple way to reset the values would earn the app the 5th star. Nevertheless, definitely the best app out there.
