★★★★★Christine Gard· May 26, 2026
Great!! I love the app how it adds up how much I have in stones. But I got a new phone, and it's not carrying over...
★★★★★Roshell Sanchez· Feb 3, 2026
I'm curious to know why this app has decided that the pieces of natural, raw, uncut gemstone, rocks and minerals are imitation. I'm not scanning jewelry. It's not Every time, but it's been reporting that some of my gems are Vitrine imitation or quartz imitation! I'd be interested in the Developer's thoughts on this.
★★★★★Jillian Collins· Jul 8, 2026
This app is a game-changer for rock hounding! It’s incredibly easy to use out in the field—I just snap a quick photo, and it instantly gives me all the details I need. The estimated stone value feature is the ultimate bonus. Highly recommend!

After downloading the app I decided to test it I started easy with some petrified wood I have it said it was Jasper then I tried banded agate it again said Jasper, so I tried Jasper, and it said Quartz everything I tried was either Jasper or quartz it hasn't correctly identified a single rock so this app is utterly useless if I could give it a negative rating I would
★☆☆☆☆Jessica Nanik· Jul 3, 2026
Incorrect Identification. Misidentified three crystals. Larvakite it identified as elaborate, nuummite was identified as onyx and my elaborate was identified as fake.
★★☆☆☆Jeannie Seibert· Feb 9, 2026
I got a bunch of rocks, and I wanted to identify them, so I subscribed to the app for the year thinking I can use this to identify all the rocks that my kids and I get. But after about 10 rocks I get this message,"sending requests to quickly" if I'm going to pay for the app I want to be able to identify all the rocks that I have.
