I am in the midst of redesigning my Android app, and I've already done it for the iPhone. I think I "nailed it" on the iPhone, however I'm having a little bit more of an issue with Android, mainly because of the differences between the two. (Most phones have hardware buttons and so on)
Does anyone have some examples of apps that have excellent usability? And why you think so?
I know most, if not all examples won't be able to directly impact my app, but I hope I'll be able to pull some commonalities out of them.
Also, what really frustrates you when using an app?
I'm not sure if this is the right place for this, but I figured I'd try anyways!
