I really like the idea of this app, and some of the features are nice. But, on my dashboard screen, some of the info boxes overlap, making them unreadable. Also, I have tried like 5 times to create an account, and it simply won't do it. I enter all info, and it takes me to the login screen...and nothing. Says an account doesn't exist for the email that I just entered. Pretty frustrating.

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.
