Identify rocks. Build your shelf.

Photograph any stone and get an AI-assisted identification with hardness, luster, streak, and lookalikes. Save finds to a personal shelf organized by stone family, attach field notes, and learn from built-in guides.

AI suggestions are educational only — always confirm significant finds with a field guide or expert.

Stone Shelf includes a daily allowance of free identifications. An optional monthly or annual Stone Shelf Pro subscription removes the daily identification limit. The app shows your localized price, renewal terms, and any trial eligibility before purchase.
