Mineral Handbook

No aquamarine

This app is just ok. It has enough content already, so there's no point going online to search in Google. But, if something can be done about the ads it could have been better

No matter what you search for, it only opens on the very first rock - abelsonite. As soon as you click back it starts loud video ads. Annoying and not functional.

Useful app but full of ads. And the ads are borderline pornographic. I think this is highly inappropriate for an educational app.

I wanted it to help me identify gemstones and minerals; this app assumes users know and just want more info. I can use the internet for that.

I just installed the app. I only looked part way through the a's, there is a lot of information. All of the listed minerals have great descriptions and most have a picture.

It is good for looking up stones

Good but too many ads!

Elegant my Ass

Good app... thanks to the developers

This is a perfect app for any gemstone on rock hunting trip or identfing rocks u dont know the name and a brief description of the rock

ITS AMAZING THANK YOU IM IN LOVE WITH GEMS!

I will send you a call from a mobile app

This App was very helpful,I enjoyed my study in geology with the help of this App, thanks much

It's very rich and detailed. Great information about any rock named in the book. Thanks.

Would buy without loud ads

Seems more interested in me seeing their ads, than in getting me the info I requested! !!!!

It's good just do further geologic apps
