I'm gonna have to nominate the Eurosport app. The content is excellent, but it seems to have been put together by blind mice. It looks ok at first glance, but once you actually try to use it for something you discover everything is a pain, and you're pretty much reduced to scrolling the main screen.
How come I use it every day? Well, it has one hidden amazing feature. Once you manage to figure out how to subscribe to a football team or a tennis player, it will give you excellent notifications on match start, goals, and set/half-time/final score. By "excellent" I mean it's very well done, with push and GCM, without taking up memory or CPU. It's the best (European) sports notification system I've used in any app ever.
