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.
i like this so much please add more things :)
Good app,but needed up gradation Plz add more rocks
Thoroughly awful. Blank database if it doesn't crash first.
Major function and UI upgrade, Give a try!
