Missing an important notification is not a lot of fun. Wearables like the nudge let you keep track of your notifications even when your phone is in your pocket. Unlike many other smart wearables, the nudge wristband lets you control which notifications you want to know about. Just pre-select your important notifications in the nudge app, and you are set.
You can filter calendar events, phone calls from a specific number, emails containing certain keywords, Faceobook notifications, and more. The SUPDWI button, which can silence your phone, is a nice touch. The battery life is good for 2 weeks. This wristband is waterproof. The product is on Kickstarter at this time.
