Is scoring your sleep worth paying for?


We spend a third of our lives asleep, so we all know how important sleep is, but are we doing it right? With the new year approaching, and ‘get more sleep’ an oft-heard resolution, you need to know the best way technology can help you do that.

There are currently three ways of learning about – and improving – your sleep patterns, in ascending order of cost.

One is to download a free ‘movement tracker’ app on your phone and record yourself sleeping; a second is to use an activity tracker, and the third is to go for a full-on dedicated sleep-monitoring device.

To compare these options we pitted the SleepBot app (which promises to track your sleep through external monitoring) against the Jawbone UP3 activity tracker (which claims to measure sleep duration and quality, and adds a heart rate sensor and an Automatic Sleep Detection feature) against a third (and particularly intriguing) device: a sensor attached to the bed itself. 

Called Beddit, it claims to track your sleep, of course, but also includes heart rate and breathing stats.

We put all three products on test for a fortnight to make a fair comparison. Ready, steady, sleep!

Beddit is a Bluetooth band that tracks your sleep

Sleep set-up

First comes the hardware set-up. Jawbone was charged up and slapped on my wrist. A slightly confusing process of pairing then ensues; I gave the accompanying UP app a lot of personal details (weight, height, age, etc) and even permission to use data from the Health app on my iPhone, but at the end I’m not convinced the wearable is funnelling data to it.

Ditto the Beddit; after peeling off an adhesive strip and sticking the 60cm-long tape to my mattress (along with a cable that plugs into a nearby socket), the Bluetooth pairing is so fast that I’m not sure if it’s successfully paired with my phone.

However, a quick lie down gives me a handy ‘live’ readout of my movement on the Beddit app. With SleepBot downloaded to my phone and having logged in and signed up, I’m all set for sleep. 

After all that prep, it’s merely a case of firing up all three apps and physically telling them I’m about to go to sleep. That’s fair enough for the SleepBot app and the Jawbone UP3, but surely the Beddit knows I’m in bed?

After being woken up by my cat in early morning, and having a restless last 30 minutes of sleep, I reach for my phone the next morning and tell all three apps that I’m awake. My phone immediately shuts down, empty of battery. Well, that was close.

The Sleepbot app covers sound as well as movement Initial results

Initial results

Once recharged, the results from all three devices are surprisingly different. The Jawbone UP3 tells me I took 10 minutes to fall asleep, slept for 7 hours and 18 minutes, had a resting heart rate of 51bpm, had deep sleep for one hour and 19 minutes, and a mere 18 minutes of less deep REM (rapid eye movement sleep).

The Beddit app agreed on the heart rate, but registered just six hours and 48 minutes of sleep. However, the results are more in-depth, as you would expect from a one-trick wearable.

As well as a ‘sleep score’ of 68/100 and a 90% efficiency rating (I understand neither, but didn’t have the best night’s sleep, so it seems fair), Beddit detected the same average heart rate, but produced a graph that tracks it slowing from 56bpm when I fell asleep to 46bpm just before waking.

It also detected four times I’d woken up, and ‘significant amounts of snoring’ at 55 minutes total, but offers few other details.

The Sleepbot app records seven hours and 36 minutes of sleep, which was the total time I was in bed. That’s it. If that seems far too simplistic, it’s mostly my fault; as well as forgetting to hit the ‘track motion’ and ‘record sound’ buttons, I left my phone on the bedside table, when I should have left it on the bed itself. 

Worse, I did it again the next night; bedtime is not the best time for in-depth gadget admin.

The Jawbone UP app is comprehensive

Week one and teething problems

On my third night of testing, Sleepbot was armed correctly, but everything else went wrong. I just couldn’t tell if the Beddit strap was talking to the app; it needs to send some kind of reassuring message.

However, the real problem was the Jawbone UP3; try as I might, I just could not get the app to put the band into sleep mode. Bear in mind I’m lying in bed here, and with every failed attempt, the band buzzes loudly. 

After seven attempts I’m ready to take it off and fling it out of an open window, but it pairs just in time to avoid my wrath.

The next morning the Beddit app tells me that I ‘took a long time to go to sleep’. Err, yup. The Jawbone then fails to recognise that I’ve woken and am moving about. You’d think an activity tracker might be able to figure that one out for itself.

It’s the same problem with Beddit, which sounds a bizarre alarm (bamboo pipes and synthesisers?) a clear hour after I’ve risen. Is it a motion sensor, or isn’t it? Beddit even stopped recording my sleep somewhere around 2:30am one night.

Was I so still that it thought I’d left the bedroom? I put both into manual mode; the auto-detect features are plain unreliable.

In contrast, Sleepbot excelled itself. Okay, so I told it exactly when I was about to go to sleep and exactly when I woke up, but I knew where I was with it. 

It also produced a detailed graph showing my light and deep sleep, and a harrowing audio log of the sound of me snoring. 

And that’s not mentioning the buzzing gadgets at bedtime. My poor wife.  

The Beddit app collects detailed data, but lacks analysis

Week two and conclusions

Teething problems over, the second week was all about collecting sleep data and seeing how the apps work.

Beddit continues to be patchy; it records heart rate in excruciating detail, but what can I do with that information? Ditto the breaths per minute. 

The app offers advice on snoring (put a tennis ball down your pyjamas, apparently), but really, there are no trends identified, or any kind of personalised advice.

There’s also one massive drawback to Beddit; you can’t take it with you. During the two weeks I stayed in a hotel and at a friend’s house, so lost two days data right there.

Some nights’ sleep were hugely over-exaggerated by the UP3

The Jawbone tries to get involved with tips and hints on sleep (and a lot more besides), but it doesn’t understand me. I’m a night owl, I’m always awake at midnight. So receiving a message at 00:01 advising me what time I should go to bed the following night is just weird.

The app also proved buggy; it was taking correct sleep data from the device, but telling me I had slept for 19 hours and 37 minutes. I even managed over 25 hours one night! I deleted and reinstalled the app, and the problem was fixed.

I also got to like the ‘smart coach’ messages after a while, which did give advice on focusing first on sleep duration, and then working on keeping consistent sleep patterns. There is a decent stab at improving sleep patterns, though there’s also a lot of unnecessary extra info; the social media-style user interface is all a bit childlike, too.

There are other drawbacks. The UP3 lasts only five days between charges, which doesn’t compare well to the fit-and-forget Beddit, and it has to be removed every time you take a shower or go swimming, two things I do pretty frequently.

However, you can take it anywhere, and it also auto-detected an unplanned 90-minute snooze on the sofa, which the others devices can’t match.

SleepBot’s ‘sleep debt’ running total is simple, but useful

It may be the least ambitious of the lot, but the SleepBot app proved both the most reliable and useful sleep tracker. 

This app may not have any way to measure my heart rate, but it does have something that both physical devices lack; access to my phone’s microphone. Apparently I’m a bad snorer, and that was really useful to know.

Since it was the only tracker that was consistent, I trusted it. SleepBot taught me that I tend to sleep for quite different lengths over a week, thanks to its simple graph, ‘sleep debt’ figure and nightly goal. By the end of the week, I’m two hours down on what I should have had. I also get to listen to myself snore…

Both the UP3 and Beddit measure heart rate

Is sleep tracking worth spending money on?  

In short, no. Heart rate is a relatively new metric to come to life-logging, and both the Jawbone UP3 and Beddit have sensors to measure your heart’s beats-per-minute. What do they do with that information? Not much. 

The automatic sleep-sensors for both failed to impress, and while the Jawbone needs regular charges, the Beddit is not good if you travel a lot.

It’s the coaching side that needs to be improved on all devices – if a device is going to collate all this data, the user wants to know what can be done with it. 

After all, these trackers are bought to know if we’re having bad nights of sleep – and if so, we want to know what to do about it.

So while SleepBot may lack heart rate monitoring, and perhaps not be as super-accurate, it’s was the app that I trusted most; it proved the best trade-off between data collected and annoyance caused.

It was also free – so it’s great as long as you don’t mind having your phone on the bed with you.

Do expensive sleep trackers have a future in the bedroom? I’m not convinced. Let me sleep on it.
