Ratings and reviews

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.

Unfortunately this is probably the best photo development timer out there. It needs a significant amount of improvements. You will get frustrated using this. Changing settings is a nightmare. You can't delete profiles. Rearranging profiles is terrible. I do not want to recommend this app but I will continue to use it for now...
