Meet the IBee: a modular bracelet with smart features to keep you connected. It comes with GPS, storage, activity tracker, notification, battery, and other modules, so you can customize your bracelet how you like. You will need Battery and Notification modules to get started. The Guardian module keeps your things safe, while the Baby Maker module measures your basal body temperature.
You also get a fingerprint button module with 5 programmable functions, a solar shield module, and a Sports module to track your daily activity and calories burned. IBee is currently available on Kickstarter.
