I’ve been using Massive Dev Chart Timer for a couple months now. It’s basically an advanced darkroom timer that comes with a huge database of B&W film development times. Super handy if you’re into film photography. And
There’s a ton of features – you can modify time and temperature, calculate volumes, and even save your own custom data. The audio agitation reminders are a lifesaver too, never have to worry about messing up your processing again.
Look, if you do a lot of black and white film work, this app is definitely worth checking out. It’s not perfect – the UI can be a bit clunky at times – but overall it’s a pretty solid tool that’ll help you get consistent results.
