Why did the typography in the Android app get changed?

This is extremely nit-picky, but originally, the tab bar at the top (containing stories, reviews and features) looked like this:

It'd be great if you could revert the font back the old one, because the new one is quite ugly (in my opinion, of course) and doesn't really fit the rest of the design of the app.
