User Reviews

The app is praised for its extensive black-and-white development database, customization, and a streamlined timer workflow, making at-home development easier. Common drawbacks include B/W-only limitations, presets-only customization, occasional crashes/UI issues, mixed views on value, and missing advanced features seen on the website (and some platform-specific quirks).

Pros

Comprehensive library of film/developer development times, covering many stocks and including the full dev chart info.
High customization: you can edit your own times and adjust saved processes.
Easy-to-use timer and workflow that reduces guesswork and speeds up darkroom work.
Digital, all-in-one reference that bundles the dev chart documentation for quick access.

Cons

Black-and-white only; no color development support.
Limited to presets; cannot freely add or adjust steps, or add new films; editing beyond saved presets is restricted.
Stability and reliability issues: crashes, white screens, and UI quirks on some devices.
Value concerns: many users feel the $8.99 price is not worth it given limitations.
Feature gaps compared with the online chart (e.g., continuous agitation, pull times) and platform quirks (safelight issues on iPad).

Recent reviews

In a recent update, when using the app in my dark room to develop sheet film, when I select, dark mode, there is still a bright white dynamic island where the mode selector is, contributing significant light pollution into my space. I’ve had to tape it off with black tape to make it usable. Why did you implement this? Is it a bug?!

In the darkroom, I rely on the ability to turn the screen of my iPhone to dark mode when using this app to time film development (sheet film, in trays). But in a recent update, there is now a large white “Dynamic Island” where the mode buttons are that cannot be turned dark, so there’s significant light pollution in my workspace when developing film, and I have to put black tape over that part of the screen!! WHY did you implement this?? Is it a bug or a “feature”??!
