Massive Dev Chart Timer

Massive Dev Chart Timer is a darkroom timer app for film photographers who develop negatives at home and need the clock, agitation prompts, and process steps kept straight. By our assessment, its strength is that it speaks the language of film processing instead of pretending to be a general stopwatch. The trade-off is narrowness: if you do not develop film, most of what it offers simply does not matter. In use, this kind of app is a workbench tool, all timing and sequence, with little charm beyond getting the steps in order. It sits in a very specific corner of photo apps, closer to lab notes than to camera editing. The right user is someone already inside analogue developing; everyone else will find it more specialised than useful.
