Maggico

Maggico is an offline guide to gemstones and minerals for collectors, learners, and anyone interested in the world of stones.

Explore a catalog of more than 40 specimens. Each entry includes its name, mineral family, Mohs hardness, rarity, and a collection of concise facts.

Open any specimen for a detailed page containing an overview, useful facts, practical tips, care guidance, and a compact timeline explaining its formation stages.

Search the collection by name, use rarity filters, or group specimens by mineral family to quickly narrow the catalog. A dedicated tab collects entries you have not explored yet, while reading marks are controlled manually so your progress reflects what you have actually studied.

The home screen features a daily mood, quick reactions, suggestions for expanding your personal specimen tray, and three selected stones to explore next.

A separate challenge tests your understanding of mineral formation. Arrange the stages in chronological order, complete each round, and review your results with a breakdown of the correct sequence.

A 28-day activity grid and weekly overview show how often you return to the collection and continue exploring new specimens.

Your reactions, reading marks, specimen tray, activity history, and challenge results are stored locally on your device.

No registration, cloud synchronization, or internet connection is required. The complete Maggico collection and your progress remain available offline.
