In terms of identifying rocks and the administration options you have, it is a fantastic app. In terms of using 4 or 5g, it is below average. Where other apps will just take a little longer to load when identifying a weaker connection, this app just refuses to open altogether and therefor is of no use when you're out and about. Pretty disappointing, I have to wait every single time until I get home to scan my rocks, really too bad.

This site has a large unacceptable issue of identifying rocks. I've scanned 2 or 3 sides and I get a different specimen on each of them. My biggest issue which Is I am unable to get a refund for my subscription . I was charged twice a week apart. I would report to my bank as fraudulent but since I authorized payment the first time, technically it's not fraud. My bank told me to straighten it out with them. Nowhere on the app or even Google's Play Store have I seen that option!! 🤯😡

I have found this to be actually quite a good database for building your collection. I do have to go out occasionally and correct the results, but it's pretty darn close most of the time. One other nice feature is that it has fairly detailed descriptions of the types of stone and their uses both physically and metaphysically.
