Is there any app available in the Android Market for Stack Exchange sites?

Answer

There are a couple of apps out there like Droidstack and StackWidget. Both of the apps can work together. I've just installed them, but so far you can't seem to answer or respond to questions with them. You can though, follow your questions and get notifications when you get answers. Droidstack is a question browser, and StackWidget lets you watch specific questions.

There is also TopStack for question browsing and SOflair for reputation monitoring. Having tried them.
