Before pretty much anyone could get too deep into this whole smartwatch thing, BAM!… the smart ring is now a thing. Smarty Ring ($275 when it goes on sale) features a built-in LED screen that connects to your phone and shows text messages, caller ID, social network updates, and more via Bluetooth 4.0. Designed for use with iOS and Android devices, Smarty Ring also promises to let you manage your phone’s apps, like its camera, and even set off an alert tone if you stray too far from your phone. If you like it, you know what to do.
