NEW: What's Beneath Ever wondered what exactly is under your feet? Now you can find out. The new "What's beneath" section in Discover shows the rock record for your area - every layer, stacked on a timeline spanning millions (sometimes billions) of years. • See the surface geology where you're standing, with just your approximate location - or look up any place by name • Scroll a time-scaled column of the rock layers recorded for your region, from yesterday's sediments down to ancient basement rock • Spot the gaps - missing chapters of deep time, marked right where the record skips. Some regions are missing hundreds of millions of years • Just identified a rock? Tap "See the rock record beneath this find" on the result to explore the geology where you found it • Browse hand-checked famous columns - start with the Grand Canyon - no location needed, works offline Geologic data © Macrostrat (CC BY 4.0). Coverage is deepest across North America and growing elsewhere. Also in this update: stability improvements and crash reporting, so problems get found and fixed faster.

About
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. Geology Toolkit goes further - explaining why a rock is what it is, how it formed, and what to look for in the field. Every identification adds to your personal field guide, building a reference you'll return to. Subscribe for unlimited identifications, full formation histories, companion mineral data, and an exportable field record. From photo to real geological understanding - one specimen at a time.
