Bromyde Darkroom

A timer, stopwatch, and chemical mix calculator built for the darkroom: large, legible, and strictly red-on-black when the lights go out.

Tip: toggle Studio / Darkroom above and the screenshots switch with it.

Timer

Countdown, your presets

Dial in minutes and seconds on custom scroll wheels and start with one tap. Four editable presets put the exposures and develop times you actually use a tap away. Long-press any preset to change it.

A big monospaced readout stays legible across the room, with start, pause, resume, and reset. Turn on an end sound and an optional metronome to keep your agitation on cadence.

Stopwatch

Open-ended, on the beat

For steps without a fixed time, the stopwatch counts up with the same clean, oversized display and the same optional metronome, with tick intervals anywhere from 1 to 45 seconds.

It keeps accurate time even after the screen sleeps or the app goes to the background, so a long wash or development is always measured correctly.

Mix

Dilutions, solved

Enter a dilution ratio like 1+9 or 1+19 and your final volume, and Bromyde Mix shows exactly how much concentrate and water to combine. Results update live as you adjust either value.

Your common ratios are saved as editable presets, so mixing developer, stop, or fixer is one tap and no mental math, even under the safelight.
