Too simple and lots of errors As cited in previous comments, many specific errors...here's another...use of sphalerite "jewelry" !...how about zinc production and galvanizing. App to be trusted only in a very limited way.
It's a great app! It has accurate information and it's fast and efficient! But one thing it's that there is a lot of different minerals out there but the app only has like 29. Please add more!
Contains nothing This contains a very limited variety of minerals. Virtually useless if rock hounding or trying to identify stones found in the field.
Good app,but needed up gradation Plz add more rocks
Thoroughly awful. Blank database if it doesn't crash first.
i like this so much please add more things :)
Major function and UI upgrade, Give a try!
