I've seen from another question that there is an iPhone app so I just wondered if there was one for Android?
I use Stack Remote.
Works for me, though to be honest I don't ever answer questions from the app.
I'll always hop on a browser and use a real keyboard.
I read the answer you pointed to and did a search on stackapps.com that they refer to.
There are some apps there, but nothing as fancy as the iPhone one
