Great app!

The beauty of this app is that the more users that there are the more accurate it becomes. Unfortunately, as an early adopter it seems the number of rocks is quite low. Too low to possibly be accurate. I will also add that many of the rocks don't appear to be rocks at all.

This app has seriously rocked my world. Before this I was never interested in rocks, but now it's my new go to hobby. I was off to a rocky start at first, but the app was so rock solid that it ended up working for the better. Rock on.

I wish my grandma were alive to see this

My granny always wondered how many rocks there were. I know she's looking down at me every time I add a rock.

And don't think it escaped me that this app joined the App Store on the same day Dwayne 'The Rock' Johnson was named People's Sexiest Man Alive.
