Very usable
I love crosswords, and gave up on other apps because they are clunky. This one gets it right. Navigation is easy, you can enter letters by drawing them on the screen instead of a keyboard (although keyboard is available too), and its very smart about various ways to move from clue to clue. Theres also a nice assortment of crosswords and other puzzles available. I have been doing a lot of crosswords because of this app. It deserves to be a lot better-known than it is.
