I keep my GPS turned off, and this app keeps trying to access my location about 1-2 times/second in the background, even after telling the system not to ask again. This makes the whole app respond extremely slowly (if at all) to my inputs, and the map is pretty much unusable unless I am willing to wait 5 minutes each time I want to learn something new.

Impressive! This app isn't a reference, it's a tool. All the maps and profiles you need to explore an area are right here, with even a Brunton compass!

LOVE THIS APP!!! It makes being a passenger on road trips infinitely more interesting. It helps me suss out potential fossil collecting sites, locally, by formation. It's so easy to spend hours on!

I've just downloaded and read all the info in this app. It looks like it will be not only enlightening and helpful in my learning about my local rocks and geography, but just plain fun. It's an app developed and produced by people who appear to know what they are doing and talking about. I'm looking forward to using it this very weekend. I will post more about it and adjust my rating as needed through out my user experience with ROCKD. Sorry I can't donate I'm currently unemployed, at this t

UPDATE: The map in version 2.6.0 is still NOT working!!! Map is completely dysfunctional. A blank layer with only the street names pushing itself in front of both satellite and bedrock layer. Doesn't make a difference whether logged in or not. Tried reinstalling, useless! When is this going to be addressed??? I would really like to use this app."
