Great stuff

I really like this app... very easy and handy to use. It's a great little timer--the thing is, you have to know your process and have your numbers down. Be sure of your times and temps--this app will make your life easier in the darkroom but it needs the right info from you.

Using the Massive Dev Chart (online) you can write up a number of "recipes" for all your developers and films etc and plug them into the app--which is what I have done and it's extremely handy. Be sure to turn your sound on for the pleasant little chime and you're good to go! Happy developing!

Pretty Cool

Pretty cool little app - I really have enjoyed using it so far. But there is one thing that annoys me and there is room for expansion and improvement! The thing that bothers me is not being able to fill in additional information for a description on what to do during interval timers, for example, 'rotate one agitation' every 30 sec, etc. Also, there is so much room for growth! This app is off on the right foot and is pretty cool, but I'd someday like to see additional links and resources, or example developing charts, or even a partnership with MassiveDevChart to be able to easily look up your developing time from the app itself (and be able to create a recipe from that time, where it auto-fills in the information for you)... Just thoughts! Great start though, and it's the most useful app out there for developing right now IMO.

Immensely helpful

This is the best and simplest app I have found for timing my developing. If there was one thing I could change, it would be being able to listen to my music or while my phone is timing. The interval chime and end task beeps pause whatever I’m listening to when they go off. I can turn them off, but they’re helpful so I don’t want to! Other than that, great app and I love being able to add my own developing recipes.
