Requires money to sort map. No thanks.

Love this app
Could be better
Good concept but falls short. I really hate that I have to find the name of a specific county before I can get info. And it takes forever to load the mineral resource info.
Paid upgrade
I bought the upgrade and havenโt noticed a change in the app or any added value in the data it provides.
Useless
Canโt even look for/see a specific thing without paying to filter your search. That means that every place that produces rocks, gravel, or clay will be a point on the map. Impossible to find what you are looking for.
Response from developer
To clarify, you see all results when you search geographically. We're sorry the free version doesn't meet your needs, but many people find the app to be useful, both with and without purchasing the upgrade, which is an inexpensive one-time purchase.
