Hi all! Can anyone suggest a tried and true free Crystal ID app. I'm a total newbie and I keep getting different answers from different apps. Or I have to pay to find out what I have. 🙄 Thanks in advance! I believe it's a "druzy" agate but I'm looking to identify the other crystals I have on hand as well.

I'd like to learn the characteristics of the crystal families so I know what I'm looking at.

I use a book… takes longer but it explains similarities and differences
