Twicca is fast becoming my Twitter client of choice. It has an amazing UI with a lot of functionality I haven’t seen in other clients. You can easily select multiple tweets or set color labels for easy visual grouping. It has a super clean floating menu that doesn’t get in the way while still being perfectly functional. And it does it all while looking soooo slick.
It does lack multi-account support, a widget, and some other deeper features but I haven’t been missing them much. I’ve got other clunkier Twitter clients still installed on my phone reserved for Swiss army knife use, but Twicca is my day to day Twitter browser of choice.
