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. :)

Thank you very much for the good description of the bug. I've fixed the issue in the new version of the app.

Still getting used to the UI. Some navigation is clunky, and I'd like an easier way to set up a process chain from scratch. That said, it worked well enough for the films I processed so far. Update: after using it for a while, I still don't like the UI, but the processes work well. After using it for a while, it's growing on me. I like it now. Compared to other offerings, this is the one to get.

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.
