Dragons Room

Dragons Room is an offline-first companion for home darkroom photographers and lab hobbyists who need precise multi-bath process control at the sink—without paper kitchen timers or guesswork. FULL-SCREEN PROCESS BOARD Chemistry stages appear as ordered bath chips: developer, stop, fix, wash, hypo-clear, and photo-flo. The active bath runs a large countdown with agitation prompts, temperature readouts, and one-tap advance so you can keep your hands on the tanks. CHEMISTRY & FILM PRESETS Start from a seed library of common B&W and color paths—D-76, XTOL, Rodinal, HC-110, plus C-41 and E-6 outlines—with dilution and time tables. Film stock cards for HP5+, Tri-X, T-Max, Portra, Ektar, and more include box-speed ISO and starter process links you can adapt. COMPENSATION & PUSH/PULL MATH A temperature compensation calculator rewrites bath times for non-standard solution temps. The push and pull helper adjusts developer duration from your exposure intent so compensation stays consistent roll after roll. AGITATION COACH Timed inversion or continuous swirl prompts with haptic confirmation help you keep agitation disciplined without watching a second clock. MULTI-TANK BATCH QUEUE Queue several reels with staggered bath starts on one phone when you are running more than one tank at the sink. WASH & FINISHING STEPS Dedicated cards for wash, hypo-clear, and wetting agent include recommended volumes and durations so finishing steps are as clear as development. LOCAL SESSION ARCHIVE Every run stores stock, chemistry, times used, and outcome notes on-device. Build a repeatable personal log without accounts or cloud dependency. WIDGETS & NOTIFICATIONS Optional Glance widgets and foreground notifications keep the active bath countdown available when the screen is off. PRIVACY BY DESIGN All data stays on your device. No account required. In-app Privacy Policy and Terms explain exactly how the app works offline. Run real film chemistry sequences with sink-ready timers, agitation cues, and compensation math—so every roll develops consistently, offline.
