Jawbone just launched a (sort of) new bracelet accessory called UP that plugs into your iPhone's 3.5mm jack to document exercise and sleep habits. The iOS companion app also allows users to track what they're eating, and combine all of the data to provide tailored health tips, and even correlate everything with your current mood.
What makes the Jawbone Up only sort of new is that it was actually released last year, then quickly clawed it back due to battery issues. To show they've gone back to the drawing board and improved everything, Jawbone put together a video of their testing and design process. We talked with the Jawbone guys back at CES about UP, if you're looking for a bit more context.
Jawbone Up is going for $129.99, and is available in a few different sizes and colors. Any takers? Who bought one when they were originally available?
