What you get
A pocket geologist, always with you
Identify a rock, then explore everything about it — properties, formation, and your own notes — all in one app.
Photo identification
Point your camera at any rock and get an answer in seconds — no field guide, no guesswork.
Properties & classification
Common name, scientific name, physical properties, and category — the data a geologist would write in a field notebook.
Formation & history
Trace each specimen back through time: how it formed, when, and which geological forces shaped it.
Field notes
Add your own notes to any identification — conditions, observations, or anything you want to remember.
Personal collection
Build a private cabinet of every rock you’ve identified, with your own notes attached.
Community gallery
Browse rocks identified by other rockhounds — and share your own discoveries publicly or keep them private.
How it works
From photo to rock identification in seconds
- Step 01
Take a photo
Capture the specimen in natural light. A clear shot of texture and color is all the AI needs.
- Step 02
AI does the geology
Our model reads mineral, texture, and color signatures to identify what you’re looking at.
- Step 03
Read the report
Get name, classification, formation, uses, and field notes — written like a real field guide.
