Rock Identification App

The Rock Identification App is a free geology companion for anyone who has ever picked up an interesting stone and wondered what it actually is. Just point your camera at a rock, mineral, crystal or fossil, and the app returns an instant identification with a match confidence score — no download or sign-up required to try it. Unlike a generic search or a heavy field guide, every identification comes backed by the properties geologists actually use to tell specimens apart: rock type, Mohs hardness, lustre, streak, texture and mineral composition. That means you're not just getting a name, you're getting enough detail to confirm the identification yourself and actually understand what you're holding. Beyond identification, the app lets you build a personal rock and mineral collection — saving each find with photos, notes and the location where you discovered it. Over time this becomes a real record of everything you've picked up on hikes, garden digs, or family outings, along with plain-language explanations of how each specimen formed and where it's typically found. It's built for a wide range of users: amateur rockhounds building out a collection, geology students who want a fast field companion, teachers running outdoor field trips, and families whose kids come home with pockets full of "treasure." Whether you're identifying a geode that's sat unlabeled on a shelf for years or naming every rock on a hike out of curiosity, the app turns casual curiosity into a proper hobby.
