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!

Great app, especially love the relevant literature results in search. UX needs some work. Search is my main use for the app, and it's annoying that it's hidden in a menu on the map view instead of surfaced on the dashboard. It's also surprising that mapping is not just part of the dashboard to begin with (if screen size is an issue, just make the stratigraphy information collapsible).

I like the app a lot. iNat for geologists and amateurs alike. But app is clunky prone to bugs and server crashes and UI is not that friendly for amateurs who don't know a lot. Also, reading GPS metadata from images would be very helpful. Web version would also be very cool. I look forward to the future of this app

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 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.
