Description
For everyone who loves minerals, gems, and rocks. This app helps you record everything you "find" and "collect" — and enjoy the hobby even more.
From discovering and sharing collecting spots to keeping your own private collecting notebook and showcasing your creations, bring every encounter with stones together in one app.
■ Discover and share spots on the map
Explore collecting spots for minerals, gems, and rocks from around the world on an interactive map. For locations and shops that are okay to share publicly, add them to the map along with photos and stone types to share with the community. Allow location access to instantly find spots near where you are right now.
■ AI-assisted stone tag suggestions
Show a photo to the AI, and it will suggest possible stone tags. Not sure what something is called? Just pick from the suggestions and start recording with ease.
AI suggestions are candidate tags only and are not a precise identification.
■ Keep your own private "Notes"
Record the stones you've found, the places you've visited, and the shops you've stopped by in a private notebook visible only to you. Perfect for managing your collection and preserving memories.
■ Share your creations in the Gallery
Post your stone-based creations — wire art, accessories, and more — to the Gallery. Browsing other users' work for inspiration is part of the fun.
