Thanks to a brand new feature in iOS7, FireChat allows you to text hyper-local singles (i.e. people within 30 feet) with no WiFi or cell service. That means the next time you see a cute girl on the subway, you can creep on her hundreds of feet below the surface of the earth. And when the world ends and the cell towers go down, survive the zombie apocalypse with 4G-free texting. Or just be lazy and text your roommate in the other room to bring you the Cheez-Its without eating up your messages for the month. Your choice.
