Excellent app that has no comparison elsewhere. The only reason its 3/5 stars for now is there are some quality of life functions that should be added, or I would suggest could be added: 1. be able to filter local check ins according to a radius you set on map, then able to filter them by most recently posted, most liked, etc. 2. Have the map not reset you to your exact location whenever you back out of reading a check in, making you scroll back in the map to where it was to read more in area

Getting familiar with the app but I am unable to scroll down on my dashboard, so some of the information (GPS and Altitude) is cut off. If there is anything below that I am unable to access it. Can provide screenshot if necessary. Looks cool. I look forward to checking it out in the field.

Update: I have been using this app for some time now, no issues, no problems. Until a weeks ago everything was fine, now it stopped working, uninstall/re-install, works once, then nothing. My phone and settings have not changed... A geologist pointed me in the direction of Rockd, I have found this the most useful app basically for everything I do rockhounding. I feel that I have mentioned the more than 100 times in my posted and comments online, reaching thousands of people.

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.

Was super excited to download and start using this app, but it doesn't work. My partner has had it for years. Starting last week, we've been met with a black screen when we open the app. We've uninstalled/reinstalled several times, with restarting our device and are still receiving the error.

Great app but one question, the mineral listing are they from what is supposed to be located in a particular area your in or, just listing's of various minerals?

John Harris Abraham

When working it was a great app...when assessing my location for geological profile it worked immediately...at present just keeps buffering.,my device is CAT S60 running on Android 6.0.1 , which should be ok..if the app requires Android 5.00+. look forward to suggestions and feedback..

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).
