I finally decided on PockeTwit for posting to Twitter from my phone. The app has an Iphone like interface with smooth scrolling menus and a full screen display. The developer is actively adding features to it and is very quick to respond to bug reports and general support questions. There’s just one trick to getting used to it, especially on a smartphone. You need to scroll left and right to get to the menus that have all of the post, reply, time line and settings. Once you get used to that you’re good to go.
