Withings Sleep Analyzer Evaluate – Tech Advisor

Most smartwatches and exercise trackers will measure your sleep too – even the Apple Watch, the final massive holdout, will quickly add help in watchOS 7 – however for these really dedicated to dozing off a devoted sleep tracker is likely to be a worthwhile funding.

Past extra superior and dependable sleep monitoring, a devoted tracker just like the Withings Sleep Analyzer saves you from sporting something uncomfortable when you sleep, avoids the chance of a battery working out mid-nap, and might assess the chance of well being circumstances like sleep apnea.

However is all that sufficient to justify dropping a bit of money on a chunk of tech you received’t even use when you’re awake?

Design and construct

The Withings Sleep Analyzer seems like a easy gray mat. You slide it underneath your mattress horizontally, in order that it lies perpendicular to your physique, underneath the centre of your chest – or as shut as you will get.

It’s simply the best measurement to suit underneath one, however you’ll want a second for those who share a mattress with a associate who additionally needs to trace their sleep. Withings says that having a second individual in mattress shouldn’t intervene with monitoring, however as somebody who examined this throughout a long-distance relationship I’m afraid I couldn’t presumably verify.

The design is totally tasteful, coated in a easy gray cloth end that appears each fashionable and cozy. That can be largely irrelevant, as a result of as soon as that is tucked underneath the mattress the one factor you’ll see anyway is the facility wire – lengthy sufficient to to stretch so far as you want it to achieve an influence supply.

Since the entire thing sits under the mattress it additionally has no affect in any respect on consolation – which can be a aid to anybody who struggles sleeping with a wrist tracker on. Because it connects to the mains there’s additionally no worries about battery or charging it up earlier than mattress – wanting an influence reduce you may be pretty assured it’ll preserve monitoring all evening.

There may be an preliminary setup course of which entails calibrating the tracker and takes 15 minutes or so, so don’t attempt to set this up the primary time proper earlier than mattress. As soon as that’s out of the way in which it’s fairly painless to make use of: you fall asleep, and also you get up to search out the leads to the morning. That’s about it.

Monitoring and efficiency

The Sleep Analyzer tracks a number of issues without delay. Like most sleep trackers, on the primary degree it tracks your motion to find out whenever you’re asleep or awake, and the way deep your sleep at any given time is.

It makes use of this and its different metrics to generate a sleep rating out of 100, with sub-categories to do with length, depth, variety of interruptions, how lengthy you took to go to sleep or get up, and the regularity of your sleep cycle – i.e. whether or not you’re normally going to sleep on the similar time each evening.

Along with that core stuff, the Sleep Analyzer is able to monitoring your coronary heart price – yup, even from under your mattress – to inform you your sleeping coronary heart price. You may see this laid out throughout the evening – recognizing spikes for unhealthy desires, for instance – and Withings says that is good indicator of your general cardiovascular well being.

A separate part of the report seems out for sleep apnea – moments the place your respiration pauses or turns into irregular throughout sleep. Somewhat apnea may be OK, lots is usually a drawback, and the app each tells you ways frequent your apneic episodes are, recommends you go to a physician in the event that they turn into extreme sufficient, and can assist generate a PDF report in your sleep you can then move on to medical professionals at that time.

There’s one remaining tracker that’s as essential in your sleep as it’s in your associate’s: loud night breathing. A microphone (which you’ll be able to deactivate from inside the app for those who favor) listens out and allows you to understand how loud and the way usually you snore, supplying you with a timeline within the morning. And women, I’m proud to report that both my assessment pattern is damaged, or I don’t snore in any respect.

The tracker waits till it thinks you’ve woken up within the morning earlier than it prompts its Wi-Fi connection and uploads the info to Withings’ community, and thus in flip right down to your app, so that you’ll get a notification shortly after you get up every morning with the final evening’s rating. Importantly it syncs mechanically, so even for those who neglect to verify the app for a when you received’t lose any information, assuming the tracker has remained linked to the Wi-Fi.

It’s onerous to evaluate how correct the monitoring is – I’ve largely bought to take the app at its phrase in fact. I can say that it could generally falsely file sleep time whereas I used to be really sitting in mattress studying or the like, so it’s honest to say that it’s not faultless – although I’ve no cause to consider it’s something aside from correct for essentially the most half.

All of this information is accessed via the Withings Well being Mate app – the identical you’ll use for those who personal a Withings watch or sensible scale, so your information will even combine properly. Your information is laid out cleanly and easily, with every rating colour-coded so as to see what’s good and unhealthy at a look

You may share your well being information with Apple Well being, Google Match, and a wide range of different well being and health apps. Sensible residence fans may additionally respect the IFTTT integration, which suggests you probably have the know-how you’ll be able to set your sensible lights to dim whenever you get into mattress, or in your kettle to boil whenever you get up.

Value and availability

The Sleep Analyzer prices £119.95/$99.95, and you should buy it direct from Withings or from Amazon.

That’s the same value to many wrist-based health trackers that additionally supply some sleep monitoring, and cheaper than the closest equal we’ve examined, the Beautyrest Sleeptracker. Withings’ possibility presents extra superior monitoring too, although the Beautyrest has the benefit of monitoring two folks with a single tracker.


The Withings Sleep Analyzer will probably attraction to 2 teams: these searching for a devoted gadget to observe their sleep apnea or loud night breathing; or those that need common sleep monitoring however don’t need the trouble of sleeping with a smartwatch.

When you’re in both group then the Withings is such a strong, dependable, and well-made little bit of equipment that it’s onerous to not suggest – although anybody who solely wants primary monitoring and doesn’t thoughts wearables will discover the advantages restricted and the worth onerous to justify.
