Card Table
We've all experienced it: you're having a dinner party or social event, and you look up only to find everyone with their heads buried in their iPhones. Now you can use that to your advantage with Card Table. This clever — and free — app lets you and up to three friends play poker, rummy, bridge, blackjack, war, or any other card game you can think of, all using a single iPad as the table and your iPhones as your personal hands. It works over Bluetooth or Wi-Fi, and is sure to liven up any tech-heavy gathering.
