I love it. But it NEEDS. A. TERRAIN. LAYER. Would also be nice if the map moved with your position. Update 8/29/22: I don't know if it was inspired by my review, but thank you so much for the terrain layer! Glad it doesn't reset the position every time I come back to the app too. Everything else is great. Spectacular update!

Good enough, but until you develop/allow a section and range overlay then im afraid its is some what limited. Without section and range I find it difficult to really orientate myself with some of the rocks and faults on your map. Would be nice to have section and range so that I could plan trips into the field with out having to do crude guesses from one map to another.

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.

Hi. Sorry you are having trouble. The map works on most versions and devices. It's very likely that using Android 7 is at least partly the cause. Please consider upgrading to Android 8 or newer.
