Thank you for making a web version (don't have Android)!
I like it, but there is one usability aspect that I would spend more UI refinement on is the boundary between Wikipedia and the app.
For example, when I click on a related article, it opens that Wikipedia page in a frame, instead of opening it in Wikiyarn. I understand why, because you want to show detailed information. But that does prevent the most important function Wikiyarn could serve: guiding the user on a journey.
