Ever picked up a beautiful rock and wondered what it was? RockFinder uses AI to identify rocks, minerals, crystals, and gemstones instantly from a photo.
IDENTIFY ROCKS & MINERALS
Simply take a photo or choose one from your library. Our AI analyzes the specimen's color, texture, luster, and crystal structure to help identify it, from common quartz to rare turquoise.
BUILD YOUR COLLECTION
Save every identified specimen to your personal collection. Add notes, track rarity, and see your growing catalog of discoveries.
ROCK ENCYCLOPEDIA
Browse 40+ rocks and minerals with detailed profiles including hardness, chemical formula, crystal system, luster, where to find them, and fun facts.
IDENTIFICATION DETAILS
Each result includes rock name, type, Mohs hardness, chemical formula, color, rarity rating, AI confidence score, and an interesting fun fact.
ROCKFINDER PREMIUM SUBSCRIPTION
RockFinder includes optional auto-renewable subscriptions through Apple In-App Purchase. RockFinder Premium unlocks unlimited rock and mineral identification, so you can scan, save, and revisit every specimen you find without the free identification limit.
Available subscription options may include:
- Weekly Access: introductory first period may be offered at $0.29, then $19.99 per week
- Yearly Access: $39.99 per year
Exact prices, subscription duration, renewal terms, and any introductory offer are shown clearly on the purchase screen before you confirm payment. Prices may vary by country or region according to App Store pricing.
SUBSCRIPTION TERMS
Payment will be charged to your Apple ID account at confirmation of purchase. Subscriptions automatically renew unless auto-renewal is turned off at least 24 hours before the end of the current billing period. Your account will be charged for renewal within 24 hours before the end of the current period.
You can manage or cancel your subscription anytime in your App Store account settings after purchase. If you already purchased RockFinder Premium, you can use Restore Purchases in the app to restore your active subscription.
FREE USE
RockFinder can be used without an account. Free users may receive a limited number of AI identifications. Upgrading to RockFinder Premium removes the identification limit and enables unlimited rock identification.
