Withings Pulse Ox Wireless Activity, Sleep and Health Tracker

Product information

With Withings Pulse Ox, you can monitor you activity and sleep, read vital signs and improve your overall health. This versatile, petite tracker includes a wristband and a clip so you can wear it your way, making it easy to keep with you, whatever you're doing. 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.

Wear It Your Way
Pulse Ox adapts to your style. During the day time you can wear it on your wrist with the included adjustable wristband, attach it to your belt or apparel using the clip or drop it in your pocket or bag and it will still track your activity. At night time, Pulse Ox can monitor your sleep patterns by using the wristband.

Keep count
Pulse Ox will track your movements throughout the day, whether you're out for a morning run, strolling around the office, or hiking up mountains. It captures steps taken, calories burned, elevation climbed and distance travelled to give you a full impression of how much activity you have taken part in. Pulse Ox makes it easy to access data when you're running too. You don't have to sync to your device- you can just press the button to see the data you need: duration and distance travelled.

Skip a beat
Pulse Ox also works as a tiny heart rate and blood oxygen level monitor. It uses 4 LEDs on the back of the device to measure your heart rate and blood oxygen level, giving you a quick view of your health status whenever you need it- all you need to do is press your finger to it. Measuring your heart rate regularly will help you look for trends- lowering it over time means that you are improving your fitness level and strengthening your heart. Monitoring your blood oxygen level is a way of assessing the overall efficiency of your respiratory function and can help mountain climbers and athletes training in high altitude guard against hypoxia.

Sweet dreams?
Analyse your sleep cycle by putting Pulse Ox in the wristband. While you sleep, Pulse Ox and the Withings app will then analyse your sleeping patterns and list key sleep quality indicators, letting you asses your sleep the next morning in order to have more restorative nights. The in-app graph shows the different sleep cycles and lists key sleep quality indicators.

Easy to understand data
Pulse Ox automatically syncs wirelessly with your iOS or Android device throughout the day using Bluetooth and a wireless internet connection to transmit the data to your free Withing's account. Data is then put into perspective in easy to understand graphs and made available in the dedicated web and mobile apps. The Withings Health Mate app turns numbers into easy to read graphs that show trends and showcase your day-to-day progress to help you better understand how your lifestyle impacts your health. You can compete with family and friends and experience real-time personalised coaching and smart reminders to help you adopt healthy habits.

Get competitive
Challenge yourself to exercise more each day, using Pulse Ox to keep track of your progress. You can even swipe across the screen to see if you've beaten your personal best from the last 10 days, giving your instant insights into your progress.

Works with other apps
There are a variety of apps for Android and iOS that are compatible with Pulse Ox, such as MyFitnessPal (which can log your meals and work with Withings' Health Mate App to compare calorie intake to calories burned), RunKeeper and MapMyFitness, so you can use the app that best suits you.

Pulse Ox features a battery life of up to 2 weeks and can be charge by a standard USB cable (included). It can also be used for an additional 24 hours when used with the screen off.

Formerly known as the Pulse O2. Following talks with a brand with legal concerns, Withings made the decision to slightly change the name of the Pulse O2 to Pulse Ox in certain regions.
For your information, there are no differences between the original Pulse, the Pulse O2 and the Pulse Ox. They all have the same specifications and offer the same advanced activity, sleep and vital sign.
