Beddit Sleep Monitor — Latest Thoughts

Note — It looks like the Beddit device is no longer being sold. An alternative device is the emFit. I will write a review on this shortly.

If we have a wearable fitness device that already that tracks sleep, why do we need a dedicated sleep tracker?

What we Measure, We Improve

While my sleep hasn’t been bad, there’s always room for improvement. A better understanding of how I slept is the first step.

Beddit Functionality

At the core of the Beddit UI is the ‘sleep score’. The sleep score takes into account quality & quantity. Quality here means overnight movement, wake time and snoring among other factors.

  • Sleep quality for the last week
  • Overnight heart rate
  • Tips on how to improve sleep

Beddit helps me improve my sleep

The Beddit sleep score & sleep history over the last seven days are useful for gauging where I am now with my sleep. The sleep tips can sometimes be helpful.

What improves and what harms my sleep

With the newly added ‘tagging’ feature in Beddit, the app builds a picture of what impacts my sleep.

Beddit keeps me accountable

Seeing my weekly sleep stats every time I set the alarm is a shows me clearly when I’m running sleep debt over many days.

Beddit brings sleep coaching

Beddit connects with my Physicians Electronic Health Record (EHR) network so that I can get my sleep data to my doctor. I can even get dedicated sleep coaches to look into two-week reports. For someone suffering from a sleep disorder like sleep apnea, this could be a life changer.

Digging in Deep

Beddit’s accuracy

The sensor in the Beddit (ballistocardiography) is the best type of sleep sensor available short of measuring brain waves through an EEG device (like the Zeo).

Accessing the Raw Data

Beddit has a feature to download raw data to a spreadsheet, which can be very useful for doing any detailed analysis. It even gives more advanced metrics like overnight Heart Rate Variability (HRV).

The Good

The UI

First thing in the morning while turning off my alarm I need a device that’s easy to use. Fortunately, the Beddit UI has that. The sleep score is clear. Scrolling down and its easy to the heart rate & sleep depth graphs.


At 99% accuracy, I’m much more confident in the sleep graphs the Beddit gives than any wrist tracking devices.

Very Active Development

The Beddit team are regularly updating the app with new features — over the last six months are tagging and trends. The Beddit 3.0 hardware upgrade has just come out with temperature & humidity monitoring. These feature rollouts will no doubt continue.

Where is Beddit lets down?

Android Users Behind the Curve in Feature

Automatic sleep tracking has been on the iPhone for over a year now but still no word on this being rolled out to Android. (Note, there are limitations in the Android platform behind this, so this might take some time still).

Not so Smart Alarm?

Alarms waking us while we’re in a deep sleep can ruin our mornings.

Data Loss?

A few times when leaving the bed in the middle of the night, no sleep was registered after.

Sleep Score?

The sleep scores don’t always match to how I feel for me. There have been times where I’ve been lying awake for hours overnight, but the sleep score or graphs don’t pick it up.

Sleep Tips

The sleep tips Beddit give are limited. Other devices like the JawBone UP3 do sleep tips well, so it was a let down to see this in the Beddit.

How does Beddit comparing to other trackers

Beddit is in the middle ground between high-end sensors and fitness trackers, so it occupies a great sweet spot there.

Wrist Based Sensors

Just because of the limitations of wrist-based devices, it’s impossible to get the same quality of data compared to the Beddit. The apps might say they’re tracking REM, light & deep sleep but these are just best guesses in reality.

High End Sensors

Compared to high-end sensors on the market (Emfit QS, ResMed S+), the Beddit stands up well.

Beddit 3.0

The Beddit 3.0, just out late 2016, takes everything in the Beddit 2.0 & adds new features, including temperature & humidity monitoring. More data will mean better sleep insights.


For so long, sleep has been a mystical beast for me. I didn’t know why I wasn’t sleeping well some nights, so I assumed it was out of my control.

Beddit Blog

Beddit has a great blog, where they discuss everything from how the devices have helped people diagnose sleep apnea to training for a marathon.
