Android: Text expansion apps are awesome on the desktop, but Android hasn't had much beyond keyboard shortcuts. Texpand fills the gap with real text expansion for any keyboard.
Unlike most text expansion solutions, Texpand doesn't care what keyboard you use. Instead, it uses an optional floating bubble to help manage your phrases, or simply autofills your phrases while typing in virtually any app (though, unfortunately, it seems that it doesn't work in the web browser). You can even set up your phrases to include dynamically-generated content like the date or time.
