NinjaSMS - what an Android app can and should be
It is SO good. Very useful, GREAT design - I'm seriously impressed with it. I know that Chatheads do the same thing (and more) but it's the design of this thing (and it's great use of Android's flexibility) that makes it so impressive.
Sorry, I'm lovestruck and I'm not making any sense! It just took the award from Google Keep as the most beautiful app I have on my phone.
