uploaded the same picture twice and got totally different answers each time. Both times, it identified the stone as a rare gemstone of some kind, not even from the part of the world where I live. It's a common rock I picked up on a Nova Scotia beach.

I tried uploading many photos, I tried different lighting and distances from the camera, I uploaded the same photo several times and turned the stones around to capture their properties all over, and this app never identified a single one correctly.

I took a picture of some black agate I bought to test to see if the app correctly identified it, but black shadow was nowhere in any of the suggestions. I also decided to scan an unidentified purple mineral I bought with it and none of the descriptions quite fit. Of course, I'm not an expert on minerals so I'll update my review again after I identify the purple rock. This app might have gotten three stars despite this, but whenever you take a picture you have to exit and renter the menu
