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. No account required — you can start taking notes right away. ■ Discover and share spots on the map Explore collecting spots for minerals, gems, and rocks from around the world on an interactive map. Search by place name to jump straight to where you want to go. 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. No sign-in needed — notes are saved on your device, and you can transfer them to an account later if you create one. Works even off the grid: take notes out in the field with no signal, and they sync automatically once you're back online. Pick multiple photos at once and crop them later. As your notes grow, search and filters help you find what you're looking for in seconds. ■ 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.

Every place people collect rocks, minerals, gems and fossils in the United States and Canada, on one map you can carry into the field. Rockhounding.org is the largest free rockhounding map there is, and this is it as an app. Find a site. Open the map and see what is near you, or search by name, county, state or mineral. Every site has what is found there, how to get in, what to bring, the land it sits on and what other collectors have logged. Filter to verified sites, fossils, paid digs, mineral occurrences or community submissions. Know the ground you are standing on. Members see BLM, Forest Service, state and tribal land under the map, active mining claims with the holder's name, and Canadian protected areas where collecting is prohibited. Long-press anywhere to drop a private pin. Take it offline. Save an area and its sites once, then use the map with no signal. Field sites rarely have coverage. Keep a logbook. Record visits and finds with photos, build your collection and see it on the map. Share a find with the community, or keep it private. Talk to other collectors. Photo gallery, forum, club directory and a calendar of shows, digs and meetings. Buy and sell specimens and gear in the marketplace. The app is free with ads. Supporter ($14.99 per year) removes ads and adds the trip planner. Pro ($59.99 per year) adds satellite, topo and LiDAR layers, land status, mining claims and offline areas. A rockhounding.org membership bought on the website works in the app, and one bought in the app works on the website.
