Whatever your fitness level or style, the Withings Pulse O2 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. And when asked, it measures your heart rate and blood oxygen level. The Pulse O2 offers an empowering experience, as you are able to better yourself by making informed choices.

Every step counts! Start tracking them to know where you stand and to see how fast you are progressing.

Analyze your running in real time with the Withings Pulse O2. When you are jogging, pressing the button once will bring forward the feedback you need: duration and distance.

With its 4 LEDs the Pulse O2 measures 2 vital signs - your heart rate and blood oxygen level - giving you a quick view of your health status.

The Pulse O2 is the smallest device to measure heart rate. It lets you check your heartbeat rate on any occasion: before a date to assess your stress or after exercising to monitor your recovery heart rate.

Also known as "The Fifth Vital Sign", the blood oxygen level is an estimation of your blood's oxygen saturation (SpO2). It is a way of assessing the overall efficiency of your respiratory function.

Time to go to bed? Place the Withings Pulse O2 in the wristband and launch the sleep cycle analysis. The next morning you will have the opportunity to precisely assess your sleep in order to have more restorative nights. The in-app graph shows the different sleep cycles and lists key sleep quality indicators - something more reliable than "impressions".

The Pulse O2 automatically syncs to your smartphone all throughout the day thanks to its embedded Bluetooth Low Energy technology. Each time the data is wirelessly transmitted to your free secured Withings account, it is put into perspective and made available in the dedicated Web and mobile apps (iOS and Android).
