Not sure if platforms (iOS vs Android) differ, but in the iOS mobile app you can make some changes. If you switch to Web View, the User CP tab/button should be available. Clicking on it will display a menu item on the left that you can edit. However, depending on the device size, it can be a bit of a challenge. For instance, rather than edit the details of the tanks I own in the details box, I found it easier to select the contents and past it into an editor (in iOS I use Notes), perform the necessary edits, and the copy and paste the updated text into the details box.
That being said, accessing is also possible in mobile app, however, I have yet to find a way to access the URLs of the existing images stored in the albums.
