Geology Toolkit uses AI to identify rocks and minerals, explain formations and create labelled pencil sketches all from a photo, then tells you the story behind them - how they formed, what they're made of and what else you might find nearby. Also includes geological information like Mohs hardness, luster, chemical formula and much more. Whether you're a curious walker who picked up something interesting, a rockhound building your collection, a student preparing for fieldwork, or a professional working in the field, Geology Toolkit gives you a considered field guide in your pocket. What you can do • Identify rocks, minerals, crystals, gems, and pebbles from photos • Read the full formation story - how each specimen formed, over what timescale, in what conditions • Discover companion minerals commonly found alongside your finds • Save specimens to your personal field guide with sketches, notes, and location • Get confidence scores and alternative identifications for tricky specimens Built for serious curiosity • Rockhounds and collectors building a field guide of finds • Geology and earth science students studying mineralogy, petrology, and classification • Field professionals needing quick, reliable identification and reference • Educators and parents exploring geology with curious learners • Anyone who's ever picked up a stone and wondered what it was Why Geology Toolkit Most rock identifier apps stop at a name.
