Ratings and reviews

I got this app on recommendation by a few friends to start tray developing sheet film. I have been using another timing app that I like but I had google credits so figured I'd try this. At first, I thought it would work fine for me but during my first dev session, the app *stopped giving any kind of audio queue*!!! I had no idea where I was in the development process, and couldn't check because I was developing in open trays. I never heard another peep from the app! App failed at the worst time

It's disappointing that the android app does not have color timing but the Apple one does. In response to reply: I have been using the app for at least four years and using it in teaching photography courses, so I understand your response. To clarify, yes this app is the same as the apple, but the Darkroom Lab Timer that does include color is not available for android.

Over all, the app is mostly good, generally I don't have any problems, but... I can't add custom times! When I press the plus to add a time, it just opens the list of development times, so nothing can be added. For as much as the app cost, you'd think that that function would work.

What's new

Fix error when editing saved development times.
