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. Beyond simple history, Rock Identifier lets you create detailed profiles for meaningful stones. Give each rock a name, add multiple photos, write notes, or record voice notes, and attach past identifications for clear context. With fields like origin, value, rarity, and custom tags, your collection becomes organized, searchable, and personal — not just a list of scans. For those interested in crystals, the app also includes information about traditional and cultural interpretations related to balance, calm, and intention.
