Massive Dev Chart Timer - User Guide
How to Save a Favorite
The best way to use the app is to store all of your commonly used Film/Dev combinations in MY TIMES. There is no reason to scroll through the entire MASSIVE DEV CHART for the dev times you use most often: simply save them in MY TIMES and jump straight to your favorites!
From the MASSIVE DEV CHART menu select the film and developer combination you wish to use and proceed to the timer screen. Click the ☆ STAR button to save in MY TIMES.
