## Review summary

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).
