Needs better user interface

For the concepts, it covers them well. There are three things that made me not rate it better:
1. It doesnt include Spanish in the Nationality Guides.
2. There is no option to bookmark your last lesson. Every time you access the app, you need to remember where you left in your previous session
3. In some lessons, information about the lesson is overlapped by the controls, and you need to juggle around to see the last part of the content
