Ratings and reviews

App is great, works just as well as the DevChart, but the timer has a slim white bar at the bottom of the screen even when switched to a safelight mode. This white bar produces ambient white light in the darkroom and must be covered with a piece of tape if you're using it near your enlarger. Could be fixed easily in a future update, but otherwise awesome!

Love this app! It has made processing prints so much easier as I no longer have to count seconds. At first, I was worried that the red light mode would still fog my paper. But as long as I turn my phone's display lighting down, there is no problem. I just have to press the red light mode button for each print I process. And I like the metronome sound counting down the seconds as it keeps me alert. Thank you for this app!

Revolutionary! Been looking for something like this as it's sometimes tough to keep a hold of agitation times and in general organise the process. I've gone from writing down in a notebook the exact minute and second I need to start and stop agitating to just having the app telling me exactly what to do with the timer and countdown feature. Stress free development.
