Snap a rock. Get a shortlist. Save your specimens. Educational ID for rocks, crystals, and minerals.
RockLedger helps you identify rocks, crystals, and minerals from a single clear photo.
How it works
1. Photograph one specimen or choose from your library.
2. Confirm the photo — nothing uploads until you tap Use this photo.
3. Review ranked candidates, confidence, and follow-up trait checks.
4. Save the result to your collection with notes and location.
Built for learners and light collectors
• Educational suggestions — not lab certification or appraisal
• Daily free scans, with optional unlimited unlock
• Collection cards stay on your device
• Plain English results and care hints
Tips for better matches
• Even light, one specimen filling the frame
• Plain background when possible
• Avoid heavy flash glare on polished faces

Results are educational suggestions only. They do not replace professional gemological testing, valuation, safety advice, or medical guidance.
