an overall great experience on my s10. had the iOS version and just thankful they didnt forget the android developers. wish the text and buttons covered more of the vertical of the screen space on my device since the buttons are smaller and harder to reach. optimizing for larger screen devices would give this a 5 star.

Disgusting! Wasted money, not reliable, always chech with the film producer the correct times. Once I used and as soon I played start the counter started from the fixing step, it made a mess on my numbers. The customer service is = to 0 . Keep my money and buy Imodium. Ps to the developer reply Are not these enough reasons to justify the asked refund? The app bug doesn't work for me. The app destroyed one negative film being not working properly because instead of starting from the develop time.

We have exchanged 29 emails with you. Unfortunately, you are wrongly and unfairly blaming our app for your film being ruined. As you know, we are working on a fix for this very random bug. You are attacking us in this forum without justification. A refund does not apply: the app is fully functional and the bug is in the process of being fixed now.

The app was okay for the couple of years I've had it but now it no longer launches and I've gotten absolutely ZERO response from the folks at the Digital Truth even after multiple "service tickets" have been opened. I'm very disappointed and will not be using it again.
