    medical data

Powerful sensing capabilities

Sleep Analyzer records and computes your health parameters in real time to understand your sleep and deliver accurate health data.

Heart rate

Each time your heart beats, it propels a mechanical wave through your body, which is measured continuously with high precision by the pneumatic sensor.


Sleep Analyzer filters your motion signal to extract your breathing rate throughout the night.


The movements of your body generate mechanical waves, which are captured by the pneumatic sensor.

Carefully calibrated. Extensively tested

Sleep Analyzer has been developed in collaboration with sleep physicians from Hôpital Béclère in Paris and extensively tested against data obtained by polysomnography (PSG) analysis, the gold standard of sleep diagnostics.

Advanced sleep tracking

Accurate data collected by the sensors is processed using exclusive algorithms that benefit from a decade of expertise in connected health.

Track Sleep Cycles




By precisely assessing the sleep stage you’re in, Sleep Analyzer helps you to monitor recovery during your night:



During deep sleep, breathing slows and muscles relax. This phase helps you recover from physical fatigue, and enables learning and memory consolidation.



Most of your dreams happen in REM (Rapid Eye Movement) sleep. REM is very important for emotion regulation and memory consolidation.



Light sleep is physiologically important but the least restorative of sleep stages. You are easily awoken during this stage.





Sleep score


Sleep Analyzer breaks down your night in 6 meaningful indicators with color-coded feedback to clearly identify the dimension of your sleep that can be improved:






1 time



Time to sleep

8 min

The Sleep Score was developed with sleep physicians to build a specific algorithm that reflects the physiological importance of each metric for the body during sleep.





heart rate tracking


Sleep Analyzer measures your heart rate while sleeping, an indicator reflecting whether enough time is spent in deep sleep and a powerful marker of how your lifestyle impacts your heart health.

Snoring detection




Track the number of snoring episodes and their durations. In the app, learn more about snoring patterns and what impacts them.

To give you a complete and accurate overview of your snoring episodes, our exclusive snoring algorithm has been trained against a dataset of low to heavy snorers. A wide variety of unwanted noises has been included in this dataset: subway noises, partner snoring, washing machine noises, cell phone vibration, and TV shows.

Sleep Analyzer can also distinguish your snoring patterns from environmental noises and your partner’s snoring patterns.





exclusive feature

Medical-grade sleep apnea detection

1 in 5 adults are estimated to have obstructive sleep apnea, and 80% of them are unaware they suffer from it. It is an underdiagnosed yet serious condition.

Why it matters

Sleep apnea causes fatigue and can have very serious health implications, including high blood pressure, arrhythmias, strokes, and heart failure.

Know how severe
your sleep apnea is


  • AHI
  • 15
  • 30

Sleep Analyzer’s exclusive algorithm analyses your thoracic and cardiac activity to identify breathing episode cessations that are characteristic of this disorder.

Not only can it detect sleep apnea, it also classifies its severity (low to mild, moderate or severe) following the classification of the American Academy of Sleep Medicine, considered as a reference worldwide.

This classification is based on the frequency of obstructive events reported as Apnea–Hypopnea Index (AHI).







"Being able to detect sleep apnea with a non-invasive device at home is a game-changer and could drastically help to better diagnose it."

—Dr. Pierre Escourrou

Sleep Physician,
Béclère Hospital, Paris

Withings Sleep Analyzer review: advanced sleep tracking made easy

Samuel Gibbs

The Withings Sleep Analyzer is a sleep tracking mat that’s simply easy to live with (...) The data it produces is good and the way it’s presented in the excellent Health Mate app is easy to follow and track across days

Samuel Gibbs

Try a Withings sleep mat. I love my data and have bought them for friends and family with good results

Withings user

Very powerful & helpful tool to improve your Health! For a limited cost, you get like a real Pro ’s equipment that ‘s help you balance you life on the right side for your health. For some’s one who cares about it, it is a must.


The sleep analyser is really useful at recording my sleep even though I get up and down to feed my baby son. I also am reassured by the sleep apnea detection .


Being a patient of acute sleep apnea, and having to wear a CPAP to sleep, I was missing statistical and realtime data on how effective my sleep was. This device and app has changed the way I understand my sleep quality. It give me data that then allows me to adjust my mask or replace it. It is a powerful tool to understand sleep quality. Use it and you will not be disappointed.


I was diagnosed with obesity and I was told snoring could be a sign of sleep apnea, so I was suggested to get a monitor. After reading online I found Withings, and love it, it is just perfect, easy to use/install, and the app is just as pretty as can be.


Pure magic. Have no idea how that measures all the data through a thick mattress, but it works and works good. The only things is that sometimes if I lay still watching TV before falling asleep it detects those moments as a light sleep. I can edit it later though.


Useful addition to my collection of health and wellness tools. It helps me to understand if I'm really getting enough sleep, or I'm feeling tiered when I wake up in the morning because of something else - maybe my lifestyle.

I've been using Sleep Analyzer and the Body+ scale. Middle-aged, I'm in good health with a normally active life-style and I've tried a few devices to monitor some body functions (smartwaches mainly). The Withings products are no doubt the best, the ones that seem the most trustworthy in terms of measurements and reliability of data. The company seems to be primarily a health monitoring company and not one that primarily makes watches, or provides computers or email services of what have you. Monitoring health is at the heart of this business and so naturally, they do it well and the tools are easy to use. In fact, my next smartwatch might just be the Withings one (especially if they make a sport-focused model) rather than one of the traditional brands.


Product itself is fabulous! Easy setup, then hands off from there on.App... Could use some work... Basic info is reasonably easy to access, but cluttered with other health stats, and buggy. In theory should be able to integrate with other stuff, but is proving difficult


We purchased the withings scales , sleep mat ,watch ,that all link together via the app .well worth whatever my husband paid for it excellent bit of kit, i suffer with restless leg syndrome ,+ sleep apnea ,the app + mat ,tell me how many times I've got up in the night +detects how bad my apnea was ,could not be without it now.


It is a great piece of kit. Easy to install and it just works. Helps me understand my sleep patterns and automate my home.

I received this as a gift as I had been looking but could not justify the cost. Really pleased with this gift as it gives great insights into your sleep and provides advice on how to improve sleep scores

Fletchy 83

Sleep analyzer is the best X-mas gift for long time. It has given me new insights to my sleeping, and what is the most important, it has really made me think about sleeping rhytm and other things that effect on sleeping quality. For me this device is fantastico :)


The Withings Sleep Analyser has learnt me much more about my sleep than I could possibly imagine. With the sleep analyser I can now determine the most suitable time of the day to take my medicine, thus minimizing the negative effects on my sleep.

Jonas MN

Straight forward installation and easy to just sleep and everything syncs to the app


Easy to install, easy to use and easy to share results with medical practitioner. Showing why I'm tired during the day and sharing this with doc


One of the best bits of tech kit I've bought. Awesome data the morning after the sleep before.

Mark Wilson

Another great Withings health product to add to my weighing machine and blood pressure monitorVery easy to set up and access information and really useful in trying to change habits to improve our sleep It diagnosed sleep apnea in my wife which I am getting checked out

Philip M

I've sued withing products for some time (scales, bp monitor) and found the sleep analyser a great addition. The device is very easy to setup and makes tracking sleep quality a breeze. The data helps form a picture of my sleep and trends over time. I share the information gathered with my sleep specialist and it assists him (and me) in the treament of insomnia.100% recommended.


Really easy to install and one starts getting useful insights immediately. I've started doing some sleep hygiene and started going a bit earlier to bed to try to get 7+ hours of sleep, which with a <1 year old baby can be challenging. But overall I've improved my sleep score already! This is great outcome for such invisible product!
