Withings Pulse 02 Activity Tracker (Blue)

The blue Withings Pulse 02 Activity Tracker can help you be more active and improve your health. During the day it captures steps, distance walked, elevation climbed and calories burned. At night, it monitors your sleeping cycles. It's also capable of measuring your heart rate and blood oxygen level, shown via four LEDs. The Pulse O2 stores data for up to 10 days, so you can see your history and how you've improved, or where you could improve in order to better your overall health. The tracker works with a free iOS/Android app and connects wirelessly to your mobile device. Both a clip and wristband are included for versatile wearing styles both day and night. Plus, it runs on a built-in rechargeable battery that lasts for up to two weeks on a charge.
