Meet Zazzi: a smart piece of jewelry that pairs with your smartphone to notify you when you have a new message and call. It vibrates on new notifications and displays a picture. You can wear it as a pendant, ring, or cuff. It is water resistant and stylish. Its battery lasts up to a week, and you can charge the device using a micro USB cable.
Zazzi is going to be iOS compatible with Android support coming down the road. You not only get vibratory feedback when you have new notifications, you can choose an image that appears on Zazzi when you have new messages. Zazzi offers Facebook integration. It even alerts you when you are separated from your phone. This cool wearable is on Indiegogo ($169 for early supporters).
