I read about a new product called the [Jawbone Up](http://gigaom.com/mobile/jawbone-up/). It’s a little blue ring that, like my Fitbit, measures the physical activity of the wearer. I bought my Fitbit just a few weeks ago but it already feels outdated compared to the Up. My Fitbit works well enough. It measures my activity even while I’m sleeping and transfers data wireless to a docking station connected to my iMac. That’s both a benefit and a limitation. The previous model, my wife has that one, required the user to connect the Fitbit to the dock to transfer information. I keep ,y Fitbit clipped to my belt during the day. I use a special wristband to store the Fitbit do that it can acquire information about my sleep cycle.

The Up has similar features. The Up is a ring that the user wears as a bracelet. It’s always on. No need for a clip. The other cool thing is that it may come in various colors. I like that blue. But, the Up biggest selling point for me I this:
>Up uses a standard 3.5 millimeter headphone jack to transfer data to a complementary iPhone application.
Sweet! A bio sensor that can sync real time data to my iPhone and correlate that with up to date blood glucose readings and food?
