Rock Identifier: Petra

Turn any rock-stone you find into a clear, confident answer.
You’re walking outside and notice a stone that looks different.
You take a photo and, within seconds, you know what it is — whether it’s a rock, a mineral, or a crystal, along with a clear name and helpful details you can actually understand.
Rock Identifier:Petra is built for moments like this. Open the app, take a picture, and get a straightforward result without technical language or exaggerated claims.
Each identification shows how confident the result is and offers possible alternatives when relevant. Instead of a single rigid answer, you get context that helps you decide and learn naturally as you go.
Every stone you scan is saved automatically. Photos, categories, dates, and confidence levels are organized into your personal collection, turning casual discoveries into something meaningful over time.
Whether you’re curious on a walk, collecting stones, exploring with your kids, or simply enjoying nature more closely, Rock Identifier fits naturally into your day without getting in the way.
No clutter. No pressure. No pretending to be perfect.
Just a clear, practical tool you’ll come back to whenever you find another stone worth identifying.
