No sign-up. Just point, shoot, and discover. HOW IT WORKS 1. Find an interesting rock on your walk 2. Take a photo with your phone 3. AI identifies it in seconds — name, rarity, and a surprising fact WHAT MAKES IT DIFFERENT Built for young explorers, not geologists Most rock ID apps are made for adult collectors.
