Gem Finder

Gem Finder is a phone app that scans a gravel bed and flags the likelys, so rockhounds pick up the good ones first instead of eyeballing every stone. Live phone flow, not a mock: a sidewalk scan returns 0 candidates at 85% or above with a splash-and-reshoot prompt, then a real gravel bed returns a ranked list at 85% or above via SAM 3.1 segmentation and Muse Spark multimodal anomaly ranking through the Meta Model API. Tap to zoom, then close-up: clean, focus, scratch test (fingernail, coin, glass, steel), then up to three possible identities, not confirmed, with supporting and contradicting evidence and a next check. Saves stay on device. Gem Finder doesn't name a species from a bed photo — it ranks candidates worth picking up, then helps you check the one in your hand.
