But for newbies trying to about minerals for the first time it really needs a photo of the mineral. ### 4/5 — Almost *2019-10-28* I really enjoy this app! Give the complete description of the minerals that I’m searching for, and ones that I was unaware of to begin with. The only issue that I have with it is that every time I choose a mineral to look up and back out of, I can’t scroll up or down until I click the search bar and cancel the search. Fix this little issue and I’ll change it from 4 stars to 5. Otherwise, this is an amazing app! ## Frequently asked questions about e ### What information does Mineralogy Database provide for each mineral?
