This is completely useless when it comes to tracking your sleep to find any problems which you may have to correct. I say this because most of the data is made up out of thin air. How can I say this you may ask. Well, I use two other sleep trackers. A Wellue wrist sleep O2/heart rate monitor which is dead on accurate. I know this because I took it to the doctor’s office with me last time and wore it while they took my vitals and the readings were identical to the doctors machine. I also use the Snorelab app on my phone which records all my snoring and interruptions. This thing didn’t match what I was seeing on those two other monitors at all.
Here’s a typical example of what this thing recorded for me last night.
First, the main data area shows your Awake, Rem, Light, and Deep sleep times. There are two problems with this “data”. First, only a Polysomnograph can tell you this as it connects electrodes to your head to measure brain activity. Last I checked this thing didn’t have electrodes to connect to my head, so this “data” is being completely made up using whatever formula they have set in the app. Lastly, the data shown is completely wrong. I was awake most of the night last night, I have really bad insomnia, the reason I know I was awake is that every half hour I’ll say the time out loud so that Snorelab can record it and I can go back and listen to it. Last night I didn’t fall asleep until a little after 4am. Yet this this says I was asleep within 10 minutes and that I was asleep all night with no interruptions for 8 hours, even though I got up once and went to the bathroom.
Second, the snoring sensor on this thing doesn’t work. my Snorelab app says I snored for 2 hours and 9 minutes and I can listen to myself snoring as well as rattling off the time every half hour until 4am. Yet this thig says I didn’t snore at all, zero, zilch, zippo. How can I believe that when I can hear myself snoring for over 2 hours in the Snorelab app?
Thirdly, there’s an area for “Breathing disturbances” which is completely useless as it only says “Few”. What the heck is “Few”, 1, 3, 5, 10? It would be nice if they could tell you how many and at what time but I know why they don’t. Here to the data is made up. I got “Few” last night but my Wellue says I had none as it would show an O2 drop if your breathing was interrupted. I believe the Wellue, as I have mentioned it’s dead on and lets you know when you move also.
The last part is the heart rate area. This thing consistently measures a heart rate that’s about 5bpm higher than my dead on Wellue monitor, but at least it sort of works unlike all the other things its supposed to measure.
Another bad thig with this device is that you are required to have a wifi connection as it sends the data to their servers and then to your phone. This is completely needless, why can’t I just have the data on my phone? That’s what my Wellue monitor and Snorelab app do. They send straight to my phone via Bluetooth, no internet required. Here to I know why they do this, they collect your data. That’s why the app needs the following permissions:
This app has access to:
Device ID & call information
read phone status and identity
Camera
take pictures and videos
SMS
receive text messages (SMS)
Identity
find accounts on the device
Contacts
read your contacts
find accounts on the device
Phone
read call log
read phone status and identity
Wi-Fi connection information
view Wi-Fi connections
Calendar
read calendar events plus confidential information
And that’s just some of them. Why on earth would they need my call logs, contacts, and calendar events to track my sleep?
Needless to say, this POS is going back for a refund.
P.S.
For all you people that give this a glowing review here’s a little challenge for you. Go lay down for 2 hours without sleeping then check to see how long you were sleeping. I actually did that once in the middle of the day and it logged it as a nap. apparently I fell asleep in 0 minutes and slept for two hours. When in fact I was awake the whole time watching TV.

Excelente medidor de la calidad del sueño. Recomiendo ampliamente este producto y revisar los demás que ofrece Nokia/Withings. Yo tengo la báscula, el medidor de presión, el termómetro y este dispositivo de medición del sueño y puedo contar que son unos excelentes dispositivos.

LLevo un año con el. En principio me molestaba tener que llevar un wearable por la noche para medir el suelo, cuando vi la opción que ofrecia Nokia, quise aprovecharlo. Funciona como se espera, aunque no tenia esperanza en que la medicion de las pulsaciones fuera tan preciso la verdad es que va de locura. La app tambien es mejor de lo esperado y cuando ya le alimentas de mas datos como peso o masa corporal, es una firme oponente para la app de salud de apple.
Por lo que vale , es perfecto. El mejor tipo de tecnologia, la que funciona y te puedes olvidar de ella,

Accuracy seems to improve the longer you use it. I still have some issues now and then, for example, back in November when we switched from DST to standard, the sleep tracker flat out stopped working around 1:15. Overall, though, I really like it and have few issues with it. I own several Withings products and would purchase again if need be. Now that I can delete my so-called “naps” in the app, it’s even better. I like to read in bed. Whenever I am engrossed in a book, the app will often record that time as a nap. Having the ability to delete inaccurate information really helps.

Ok, I do not ordinarily write reviews unless I am very impressed and this sleeping mat really impressed me. I have tried a variety of sleeping mats/sensors in the past and the single biggest problem with them all (other than this one) is that they require you to use your phone to record the sleeping data. With other mats, you need to remember to open an app on the phone and you need to store all the data on your phone, which gets very annoying after a short while. Not with this mat, the sleeping mat communicates with Withings directly over wifi and all your sleeping data is stored on their website. Your phone is just used to view the data whenever you want, you can delete the withing app from your phone and it will not erase the data. The other important thing about a sleeping sensor is the accuracy, a sleeping mat/sensor is no good if it is not accurate, and this one is meeting my accuracy standards. You do need to be careful where to put the sensor (they say under the sternum) but once you do that, then you don’t need to worry about placement ever again, or even need to think about the sensor ever again. It just records your sleep every day without you ever having to think about it. This point is not to be under estimated, I have 10 years of daily weight data stored on the Withings website, because I use their weighing scale. And no, I am not giving them 5 stars just because I own their weighing scale, I would simply not bother writing a review if I was not truly impressed with the product. I am going to come back and update this review after 1 year, the true value of a good sleeping sensor is in being able to consistently produce a good measurement every day.
Update after 1 month:
1. Robust: I have used it for a little bit less than 1 month now, and I have a reading from every day. This is a first for me, my previous sleeping sensors never made it so far.
2. Accuracy: Accuracy is not super good but not super bad either. If you lie still in bed and do not move, this sensor will put you down as “REM”, and the other deeper sleep settings can be fooled too. I think i have to leave the bed or sit upright for it to think that i am awake, otherwise it thinks that i am asleep. If the sensor is able to measure my heartrate and i don’t move much, it has me down as asleep. Not complaining to be honest, I am not sure how much better someone else can do either.
3. Speedy reading: Typically i get the results as soon as i get out of bed, within 5 mins. On a few occasions, it has take longer. Sometimes as long as 6 hours. I think the sensor tries to connect to the website, if it is not able to connect, waits for a few hours before retrying. Not sure exactly what happens in the few instances. But I have always managed to finally get a reading from the previous night, even with those delayed instances. I see a lot of negative reviews and I feel that this could be a cause of concern. When you don’t see the results right away, you get nervous that the sensor could be broken.
4. Five Stars: Yes, I still give this product 5 stars despite everything. Competitors take note, this is the first time that a sleeping sensor has been able to track my sleep for as long as a month, and the data is stored safely in Withings website. I don’t think any other sleeping sensor competitor can say they do as good a job, including the mighty Apple. I am afraid that making a good sleeping sensor is so hard, that people might simply think it is not worth the effort.

I was pleasantly surprised to discover that the Withings Health Mate app DOES in fact display your Deep Sleep as not only hrs/min, but also % of the night. Ditto the REM sleep & light sleep. At least it does as of Aug 2023 (see pictures/screen-shots in my review here). I had an impossible time trying to confirm this ahead of time, before I made my purchase.
I am docking 1 star for the accuracy, as I suspect these #’s I’m may or may not even be all that precise. Last night for instance I had a horrible night’s sleep: tossing and turning, constantly waking up during the night, very shallow type sleep that felt like I was half-awake the whole time. The Withings Health Mate app actually displayed a whopping 30% Deep Sleep the next morning, which there’s no way that’s even close. Felt more like about 3% of my night was Deep Sleep instead.

O aparelho detecta com certa acurácia o sono profundo, REM e superficial, mas tem basicamente a mesma acurácia que um monitor fitbit ou amazfit, bem mais em conta, mas com maior precisão do Withings na identificação de sono REM. ele fornece, no atual aplicativo “Health Mate” do IOS, a % de cada fase do sono. falta um luz indicativa de que o aparelho está ligado e conectado à fonte (não tem como saber se ele está funcionando senão pelo proprio aplicativo). também ele não parece possuir memória: em caso de falta de energia antes de sincronizar com o celular, os dados daquela noite são perdidos. senti falta da gravação dos roncos (o aplicativo informa só o numero de roncos e a % da noite em que roncou). o Health Mate não fornece gravações, como acontece com aplicativos Ios como Sleep Cycle, nem calcula o intervalo entre os roncos, como alguns aplicativos como o MyNight faziam, que poderia ser usado para suspeitar de apnéia do sono. O Withings tb não fornece dados sobre a posição da pessoa (que poderia ser correlacionado com os roncos do Sleep Cycle) como acontece com bandana Muse. O Withings tb à s vezes demora um pouco pra sincronizar com o celular, e só o faz DEPOIS que a pessoa se levanta da cama, diferente dos relógios/pulseiras. Mas de uma forma geral, é um bom produto.
Reviews de resaca –
Io non so come faccia! Lo uso da qualche settimana, ed è precisissimo. Per esempio rileva se mi sveglio e mando un sms, per poi riaddormentarmi. Senza praticamente muovermi, ho spostato la mano per prendere il telefono sul cuscino e rimetterlo giù, ed ha rilevato che in quei secondi ero sveglia. Mi interessa molto sapere come va il battito cardiaco nella notte, stanotte per esempio ho avuto un incubo piuttosto brutto ed ho rilevato un picco molto alto dei bpm all’ora in cui mi sono effettivamente svegliata. Ho anche scoperto che ogni tanto russo per qualche minuto 🙈.
Sono molto soddisfatta di questo prodotto, l’installazione è semplicissima e l’integrazione con l’app perfetta.
Se non si dorme a casa, i dati mancanti non vengono considerati (non funziona come Apple Watch, per esempio, che se si scarica o non si indossa abbassa la media delle calorie consumate o dei dati di movimento).

Works well, but make sure it’s got a 2.4ghz wifi connection to connect to. A wifi 6 router won’t work, the data doesn’t show.
