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.

The app’s stone identification is too simplistic. It mostly scans a single-angle photo and guesses what the stone might be, but doesn’t provide detailed characteristics or properties of similar-looking stones. When many stones have visually similar patterns, it's hard to tell them apart based on image alone. Without in-depth descriptions or comparisons, users can't clearly understand why a particular result was given.

Thank you for your thoughtful feedback on our stone identification feature. To improve accuracy, try taking multiple photos from different angles and in good lighting conditions. This can help our AI better analyze the stone's characteristics. For personalized assistance or to share more specific suggestions, email us at [email protected].
