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!
Good app,but needed up gradation Plz add more rocks
Contains nothing This contains a very limited variety of minerals. Virtually useless if rock hounding or trying to identify stones found in the field.
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.
Good for mining engineers I am studying second year in ME so it is useful for me thanks a lot
KEY: Minerals Key fits and opens what you need open
