Ratings and reviews

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.

Exceptional app for developing film. Pick your film, pick your developer, and go. Great for daylight tanks and developing at the kitchen sink. Tray developers ... darkroom use ... your mileage may vary. Since I only develop roll film in tanks, I don't have the problems darkroom users have. Read the reviews to see if this is the app for you.

I love the idea, and have been using this for years. However if you use a lot of developers and films, this will quickly become useless. The 'my times' pane shows each film/dev in its own row. If you routinely use 5 films and 5 developers, and perhaps want to keep times for 3 different temperature levels, you're left with scrolling through a massive list of 75 rows to go and find your desired dev plan. It would be good instead to be able to collapse all this data in nested lists, e.g. by film.
