Identify rocks and minerals from a photo, then understand what you're holding.

Geology Toolkit is a rock identifier built for people who want more than a name. Take a picture of a rock, stone, crystal or gem and get the rock type, its principal minerals and a clear explanation of how it formed. Igneous, sedimentary or metamorphic, the app tells you why.

ROCK IDENTIFICATION FROM A PHOTO
• Point your camera at a hand specimen or upload a photo from your gallery
• Get the rock or mineral name plus the composition, texture and hardness that back it up
• Use it as a rock scanner in the field or to identify rocks you've already collected

MINERAL AND CRYSTAL ID
• Identify common minerals, crystals and gems and learn the properties that set them apart
• Mohs hardness and key characteristics for every result, not just a label

EXPLAIN ROCK FORMATIONS
• Photograph an outcrop, cliff face or road cut and get a plain-language explanation of the formation and the processes that shaped it

WHAT'S BENEATH YOUR FEET
• See the stratigraphic column under your current location: the rock layers, their ages and how they were laid down
• Best coverage in the United States, with more regions to come

YOUR ROCK COLLECTION
• Every identification is saved to your collection with a map of where you found it
• Build a field log you can revisit for coursework, field trips or rockhounding

LEARN SOMETHING EVERY DAY
• Rock of the Day: a new specimen daily with its composition, where it's found and why it matters
• Quiz of the Day and practice quizzes to test your rock and mineral knowledge

SKETCH TOOL
• Turn a rock photo into a labelled pencil sketch for field notebooks, reports and revision

WHO IT'S FOR
• Geology and earth science students revising rock types and mineral identification
• Rockhounds and collectors who want to identify rocks they find
• Hikers, beachcombers and anyone who picks up a stone and wonders what it is
• Teachers and parents looking for a geology app that explains rather than just labels

WHY GEOLOGY TOOLKIT
• Powered by a frontier class AI model, with explanations grounded in composition, texture and formation, so you learn with every identification
• Works on rough hand specimens and outcrops, not only polished samples
• No account needed to get started
• Available in English, Spanish, German, French, Japanese and Portuguese
