Ishikoro Explorers:Rock Finder

A rock identifier built for kids and families.

Snap a photo of any stone and AI tells you its name, how rare it is, and a fun fact, all in simple words your child can read on their own.

No account. 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

Rocks, minerals, crystals, gemstones, and more. Turn any walk, beach trip, or hike into a treasure hunt.

WHAT MAKES IT DIFFERENT

Built for young explorers, not geologists
Most rock ID apps are made for adult collectors. This one is made for children. Every explanation is written in plain language, with no technical jargon to get in the way.

A rarity rating that makes every rock exciting
Is it an ordinary pebble, or a rare gemstone? Every scan reveals a rarity score from 1 to 5 stars. Find a 4 or 5-star rock and confetti fills the screen.

Fun facts that spark curiosity
"Ancient people used this to make fire." "This is actually a cousin of a gemstone!" Each result comes with a fact designed to make kids say "Whoa!" and to open the door to science and geology.

Build your own collection
Every rock you find is saved to your personal field guide. Collect more to rank up through 10 levels, from Beginner Hunter to Stone Master, and earn badges along the way.

A new quiz every day
Answer a daily question about rocks and minerals. Keep getting them right to unlock special badges.
