I just knew it had to happen sooner or later. That the bucket shop heralds out there (the ones willing to sell you "your family coat of arms" or even worse, "your family crest") would take the digital plunge. There is now an "app" (I don't know why they can't call them "applications" or even "programs", but no, "apps" it is) for the iPhone (and, presumably, the iPad) entitled Irish Heraldry.
This app (now only $0.99! Down from an original price of $2.99) contains over 1,200 Irish "Family Coat of Arms", in full color with an "Irish font", an alphabetical surname menu, hand drawn images, and, of course, a link to a website where you can have your "crest" printed on various products (presumably coffee cups, coasters, and the like) which you can also have personalized.
"This app is great for those with Irish surnames or interested in Heraldry and family history." Or, of course, for those who already have a little knowledge about Irish heraldry, maybe it isn't so great.
Either way, you can learn more -- if you choose to do so -- on-line at: http://appshopper.com/reference/irish-heraldry
