If you've got a little Erin in your go Bragh, you'll want to be able to show it off on March 17th. And while the Irish Heraldry app has been around since December, tis finally the season to get your Irish up. The app packs in 1200 Coats of Arms, full color family crests, and a guide to what those symbols actually mean. Because you never know when you're going to need to back up that "Kiss me, I'm Irish" move. [iTunes]
