Not user-friendly at all

Ads are really annoying, especially the video in front of main view; I had no idea what was going on while I tried to load any lesson, it takes long time to load and no sign of loading. Controls on the top is not a good idea too, it intersects with status bar and that drives me nut. Hate the fact that the lessons content is allowed to be zoomed out more than it needs.
