RockyDoo
What IS this rock?
Now you have an answer — one your child can actually read.
A purple crystal that grows in secret pockets inside rocks. Wow!
Point the camera. Tap once. RockyDoo identifies rocks, crystals, gemstones, minerals and fossils in seconds, and explains each one in words written for your child's age — not for a geology textbook.

Written for your child
You enter a first name and pick an age range once. Every explanation from then on is pitched at that reading level, and greets them by name. A four-year-old and a ten-year-old get genuinely different answers about the same stone.
A collection that's theirs
Every rock they identify is saved with the photo they took — the real one, in their hand, on that walk. It builds into a collection they can scroll back through for years.
Cousins to hunt for
Every result suggests related rocks to look for next, with photographs. It turns a walk to the park into a treasure hunt.
Built for families
No accounts. No sign-up. No ads. No analytics and no third-party tracking. Your child's name, rocks and photos stay on the phone. A parental gate stands in front of anything that costs money.
What you get for every find
- The name, and how confident we are about it
- Its colors, and how hard the stone is
- Where in the world it's usually found
- How rare it is
- One fun fact worth repeating at dinner

Made by a dad
RockyDoo started because a small boy kept coming home with his pockets full of rocks, and kept asking what they were. It got good enough to share.
