## Description

RockCheck is an educational Chrome extension designed to aid in the identification and study of typical rocks. Ideal for students, educators, and geology enthusiasts, it serves as a practical teaching tool within natural science subjects. The extension features three main components:

- **Rock Key:** An interactive identification key that guides users through a series of YES/NO questions to identify selected rocks, with helpful links for further explanation.
- **Encyclopedia:** Provides detailed information about rocks, their characteristics, formation, and practical uses.
- **School of Rock:** Offers educational content to help users understand geological concepts and procedures.

Developed as part of European educational projects and funded by notable institutions, RockCheck simplifies rock classification based on standard geological criteria, making geology accessible and engaging for formal education and enthusiasts alike.

## Review summary

RockCheck is easy to use with quick identification and an informative reference. It’s free to use for basic features and can be handy in regions like Colorado. However, many users complain about a very small rock index, lack of image-search/scan, and occasional inaccuracies that reduce reliability. Some reviews also note the need for a paid subscription for full features, which limits its usefulness for serious rock and mineral identification.

### Pros

- Very quick to identify minerals and rocks.
- Informative, encyclopedia-like reference with lots of information.
- Free to use (core features available without paying).
- Handy, especially for Colorado.

### Cons

- Limited rock/mineral index (about 33 rocks).
- No image-based identification; no camera/photo scan feature.
- Inaccurate or unreliable results in some cases.
- Requires a paid subscription for full features.
