### 5/5 — Exceptional App

*2026-01-17*

I tested it on known variants of fluorite and it was right every time.

### 1/5 — Do not get

*2025-07-09*

I just downloaded this app because I have a HUGE rock collection and I wanted to see what they all are. I looked through all the rock ID apps and this one was the best and was free. I just scanned like 20 rocks and none of the results were even close to what the rock looked like. And there are ads. So many ads! I really hate this app. Please fix or I'm deleting it, and guys, please don't download this, you'll thank me later.

### 1/5 — Awful

*2025-07-05*

I got this app because I wanted to identify some rocks and this app was free, so to test if it was good I took a picture of a stone that I knew was amethyst but it said it was something completely different. If you want an advanced rock identifier then definitely don’t download this app.
