Withings Pulse O2

The Withings Pulse O2 tracker is like a nagging doctor that constantly measures you, but all for your own good. It checks your activity level by counting steps, elevation, distance ran and calories burned. It can also give vital sign readings like heart rate and blood oxygen level as well as monitor your sleep cycle. All this data can then be analysed by the Health Mate app for some real time coaching. Oh yes, and it can tell the time.
