Any basic app that cannot find Realgar[AsS] isnt extensive enough for identification purposes. This may help a Elementary school project or paper but is t going to help any High School or college lvl need.

Highly informative app, packed full of facts. It doesn't have the identifying capabilities that I would like but it has all of the necessary information for you to come to your own conclusions on the identity of the different kinds of rocks that you may encounter.

Zounds! If you have any interest in rocks, this app has the information you need. Very complete, with more data than I've ever known before.
