Features & Capabilities

Darkroom Formulas contains a database with over 160 chemical formulas from Digitaltruth.com including film developers, print developers, toners, reducers, intensifiers and more. Users can edit existing formulas or add their own favorite recipes.

The app contains a powerful Volume Mixer allowing all ingredients to be adjusted proportionally on-the-fly. No more messing around with complex calculations, simply change the final volume and every ingredient changes automatically!

Your own saved formulas can be exported and shared by email, or stored externally as a back up.

The app includes all the data internally, so there is no need to connect to the internet to use it. Simply download and store in your pocket. Ideal for lab technicians and other darkroom users who need to mix formulas from scratch.

Formulas can include up to 3 part mixes (eg. Part A, Part B, Part C) and each part can contain up to 10 ingredients, allowing a maximum total of 30 ingredients. Available units are ml, g, fl oz, oz, tsp, grains and drops.

Lifetime free updates, no ads, no add-ons.

I can’t see the ml to adjust volume. White font against white background. Waste of money
by hu*****, 2025-09-21

The app is currently, as I write this, incompatible with Dark Mode. Attempts to change the quantity of finished chemicals result in white text on identical white background. I want to love this app, but dark mode needs to be fixed.

After just having downloaded this app (attempting in both iPhone and iPad), this app appears broken at present. The opening menu does not render beyond halfway down the length of the screen. Other screens are similarly broken. Of note, I tried the total volume selector inside the ‘new chemical wizard’, and got no keyboard or number prompt. Nor could I access any sort of dialog box. Please have a look at the code base.
