The app could use a pull out tab.

There exists no log out option so far. There is no place for that in the app so far. Therefore I suggests something like this below where you pull out or click on a thing and a pull out tab appears with vital information.

Hamburger menu can be accessible on the main page. It is not an action you do often, so it shouldn't take space in other places.
