The app does well most of the time but a known sample of Himalayan rock salt was misidentified twice. once as Carnelian and once as Calcite. on the third try, it finally selected Pink salt. Many of the descriptions that appear have names in differing languages/characters. Some of the IDs are quite good and the selection of reference minerals is quite expansive. Overall, this app is kinda fun, but is nowhere near consistent enough to fully trust

Not remotely accurate. Tested numerous difference gems, knowing for sure what they are, and it was completely wrong. Tried different lighting, different angles. It got nothing correct. It also gives different identifications for the same gem after submitting the same picture of it multiple times. Useless application. Do not rely on it for anything. Best to get your gems and stones formally identified and/or appraised.

This app lies right out of the gate. It doesn't mention anywhere before installing that or is NOT free. You get a couple of pictures that, right away, it missed the very first stone I tried to get out to identify. But it is NOT free. Any app that lies to me right out of the gate gets no stars and is deleted. And there is literally nowhere that gives you the option of canceling the forced "trial." It also doesn't say you are automatically signed up for their "free trial" just by opening the app.
