Identify any rock, crystal, mineral, or gemstone from a single photo. Found a stone on a hike? Picked up a crystal at a fair? Point your camera and Geode tells you what it is in seconds — no guidebook, no guesswork. WHY GEODE IS DIFFERENT • Five full scans every day at no cost — no account required, and never a single ad • Your value estimate is shown up front, not locked away • Honest results: when Geode isn't sure, it says so and shows you the look-alikes — instead of inventing a confident wrong answer • Consistent: the same photo won't flip to a different stone on the next try EVERY SCAN GIVES YOU • Instant identification with a confidence reading and common look-alikes • Physical properties — Mohs hardness, crystal system, luster, streak, chemical formula • Geology — how it forms and where it's found • An estimated value range, in plain language • Crystal meanings — chakras, properties, zodiac, cleansing and care (in Crystal Keeping mode) CHOOSE YOUR LENS Prefer the science? Field Guide mode keeps it to mineralogy. Into the spiritual side? Crystal Keeping mode adds chakras, zodiac, and care — cleanly separated, so you only see what you came for. BUILD YOUR COLLECTION Save every find with your own photos, notes, locality, and size. Track your collection's value, keep a wishlist, and export a beautiful field-guide "specimen sheet" to print or share. Perfect for rockhounds, crystal lovers, students, beachcombers, and anyone curious about the stones around them. AI identifications and value estimates are for educational use and are not a substitute for a professional gemologist. ——— This app offers an auto-renewable subscription ($4.99/week, $9.99/month, $29.99/year).
