Find something good on the beach, in a creek or on a trail? Walk with your camera pointed at the ground and Rare Stone brackets the rocks worth picking up. Pick one up and it tells you what it is, whether it's worth keeping, and what it's roughly worth. WALK, SPOT, PICK IT UP • Live finder: walk slowly and Rare Stone brackets the rocks worth a closer look (gold for the special ones), and names them as you get close • Pick it up: hold a bracketed rock close to the camera and its full card opens on its own, no tapping • Its most likely name, plus the next-best guesses, and a plain "likely" or "possibly" so you know how sure it is • Keep or drop: whether a collector would take it home • Why: the features in your photo that point to the answer • A quick field test to confirm it: rinse it, backlight it, try a streak or a magnet • Where it's usually found, and whether that fits where you are • Rarity: common, uncommon or rare, with a special moment for rare finds WHAT'S IT WORTH? Rare Stone gives a realistic price range for a rough specimen like yours, and what would make it worth more. Most rocks are worth little, and Rare Stone says so. It's an AI estimate, not an appraisal. BUILD YOUR COLLECTION • Add finds to My Finds with a clean cut-out photo, where you found it, and your own notes • Tick off a checklist of 50 rocks you can find in the US, and earn badges • Share your trip: how many rocks you scanned, kept, and how many were rare WHERE TO LOOK • A rock map: pick agate, geodes, fossils, sapphire and more to see where each one lives, famous US places to find it, and public spots near you • Public places near you where people find rocks, crystals, fossils and sea glass: beaches, creeks, parks and fee-dig mines, with access notes • See what other Rare Stone users have found in your area (approximate areas only, never names or exact spots) LEARN IN THE FIELD • Built-in guides that work offline: 7 pocket field tests, is it an agate, is it a meteorite, real vs. fake, where it's legal to collect, safety, cleaning, hardness and value PRIVATE BY DEFAULT • Start scanning without an account; sign in with Apple or Google later to keep your finds when you switch phones • Sharing photos to improve Rare Stone and using your location are both off unless you turn them on • Faces are blurred and photo location data is removed before any photo is stored • Delete everything from Settings at any time FREE TO USE Rare Stone is free, with no subscription. Turn on "Share my rock photos" to identify with no daily limit for everyday use and help teach Rare Stone's own rock spotter. With sharing off you still get 3 full identifications a day, and safety warnings are always shown.

Walk slowly with the camera pointed at the ground and the live finder brackets the rocks worth picking up. Pick one up and hold it close, and its card opens on its own. • Faster brackets: each part of the view shows up as soon as it's checked, instead of waiting for the whole look. • Better on weak signal: the finder sends smaller images when your connection is slow, and tells you when you're offline. • If you share your rock photos, what the live finder sees as you walk now helps teach Rare Stone too. You can turn sharing off anytime in Settings. ### 1.3 — 2026-11-09 • Live finder sees farther: every few seconds it takes a closer look at the whole scene, including zoomed-in sections, so small rocks further ahead get bracketed • Sharper close-up checks before a rock is bracketed • A "Checking…" label while the finder takes a look • Fixed: "Reset to defaults" in Settings now keeps the live finder on • Smaller fixes and speed improvements ### 1.2 — 2026-11-05 A fresh new look, and a live finder that spots the good rocks for you. • Live finder: walk slowly with the camera and Rarestone brackets the rocks worth a closer look. Interesting ones get a gold star, and the name firms up as you walk closer or pick the rock up • All-new design, with a new icon • Rarity now shows as 1 to 5 stars that glow brighter the rarer your find • Size is worked out for you: no more picking how big your rock is • Smoother Rock map with public spots near you • Smarter on-device rock namer that now knows fossil bone • Speed and accuracy improvements ### 1.0 — 2026-11-03 No release notes. ## More apps by Jason Rosen - [Motor Notice: Car Deal Alerts](https://appshunter.io/ios/app/motor-notice-car-deal-alerts/id6759541262) All apps by Jason Rosen: https://appshunter.io/developer/1879395956 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
