Withings Pulse O2 keeps tab on your oxygen levels

Withings has announced a new health band called Pulse O2. It does all of the usual stuff, like monitor steps, heart rate, elevation, distance traveled, sleep habits, and estimates calories burned, but the really cool feature here is the ability to monitor the oxygen level in your blood. That information is estimated from the infrared heart rate monitor, then beamed to your phone through a companion app. The device itself can be mounted in a wrist strap, a clip, or carried around separately.

As promising as this looks, fitness bands are a tough business to get into. Not only is the plenty of competition, but established players like Nike seem to be backing away from the market.

The Withings Pulse O2 will be available to buy for $119.95 here. Do you already have a fitness band? How much health data do you need to track on a daily basis?
