DarkRoom Chemist takes the guesswork out of the lab, providing a streamlined, intuitive interface to help you achieve consistent, professional results every time you crack open a tank. CUSTOMIZABLE WORKFLOWS Whether you’re shooting 35mm, medium format, or large format, every roll requires a unique touch. Create custom development processes or start instantly with built-in templates for: • C-41 Color Negative: Precisely timed for the critical developer stage. • B&W Film: Fully adjustable for your favorite film and developer combinations. • E-6 Slide: Manage the complex 3-bath or 6-bath slide processes with ease. INTELLIGENT TIMERS & AGITATION CUES Never miss a turn. Our interactive timer guides you through every stage—Developer, Stop Bath, Fixer, and Wash. • Haptic Feedback: Feel the agitation cues even when your hands are busy. • Stay Awake: The "Keep Screen Awake" feature ensures your timer never goes dark in the middle of a critical step. • Dual Units: Seamlessly switch between Celsius and Fahrenheit. TRACK YOUR RESULTS The journey doesn't end when the film is dry. Use the integrated Chemistry Gallery to: • Import photos of your developed rolls. • Link images directly to the chemical process used to create them. • Store notes on exposure, dilution, or temperature for future reference. PRIVATE & SECURE Your data belongs to you. DarkRoom Chemist uses the latest Apple technologies to store your processes and photos locally on your device. No accounts, no cloud tracking—just you and your craft. Bring your film to life with DarkRoom Chemist. Precision in every drop.

What's New in Version 1.3 — The Darkroom Update The biggest update yet, built around one idea: you shouldn't have to look at (or touch) your phone while your film is in the tank. • Live Activities — Follow your timer from the Lock Screen and Dynamic Island: current step, live countdown, and progress, no unlocking with wet hands required. • Step alerts anywhere — Get notified the moment a step finishes, even when your phone is locked or you're in another app. • Sound & voice cues — Hear a tone or a spoken announcement ("Agitate", "Next step: Blix") for agitation and step changes. Perfect for total darkness. • Darkroom Mode — One tap washes the entire app in dim safelight red for printing sessions. • Temperature compensation — Chemistry running warm or cold? Enter the actual temperature and your developer times adjust automatically to match. • Run history — Every completed development session is logged automatically — process, time, temperature — with room for your own notes. • Chemistry tracking — Track each mixed batch of chemistry and how many rolls it has left, with a warning when it's exhausted. Log a roll right from the finish screen. • A more accurate timer — Rebuilt to stay exact through screen locks and interruptions, with target temperatures shown during the run. Plus: confirmation before deleting gallery photos, support for steps over an hour, and other fixes.
