Are there mobile apps for Stack Overflow?
Does Stack Overflow have a mobile application?
I mean a smartphone app for iOS, Android or Windows Phone?
There is a mobile view of the website you can access here
But there is no official app.
Droidstack works really well on Android - it supports full logging in, and copes well with chat. I use it for my main SE sites when on the go.
Its only glitch is when trying to migrate - the options given are not selectable, but that isn't a major issue.
