## What is Darkroom Companion?

Darkroom Companion is a clean, modern helper for developing black-and-white film at home. No account, no ads, no tracking — it works fully offline.

Whether you are developing your first roll or your thousandth, it keeps the whole process in one place.

FREE — NO SUBSCRIPTION, NO ADS

• Multi-step timer — developer, stop bath, fixer, wash, wetting agent — with sound and haptic agitation cues
• Night (red) mode that preserves your dark adaptation
• Development time calculator for bath temperature and push/pull (± stops)
• Built-in database of times for common film and developer combinations
• Dilution calculator — how much concentrate, how much water
• Celsius or Fahrenheit, whichever you think in
• Reciprocity calculator for long exposures
• One custom recipe and the last three developments in the log

DARKROOM PRO — one-time unlock, no subscription

• Unlimited custom recipes and custom process steps
• Chemistry log — tracks expiry and exhaustion, warns you before you pour dead fixer
• Unlimited development history
• Data export and import

Times are indicative. Verify them against the manufacturer datasheet before real use — the app reminds you as well.
