The Eight app requires an Eight Sleep Tracker. Get yours at

Eight has everything you need to sleep better and wake up refreshed; advanced tracking of sleep data and trends, dual-zone temperature control of the bed, a smart alarm that wakes you up at the best time each morning, and more:

Track your sleep without having to wear a device—no phone in your bed or clunky wrist wear. Eight’s mattress cover uses proprietary sensor technology and advanced data analysis to work on any mattress, for every body.

Each morning, Eight shows you all the data for your last night of sleep, including time slept and sleep stages. The Sleep Score gauges your overall sleep performance, summarising key sleep data points.

On a weekly and monthly basis, Eight aggregates your sleep data to display trends and averages over time. Using this information, Eight shows you insights and identifies ways to improve your sleep.

Use the app to set sleep goals and preferences. Eight uses this information to give you personalized advice and tips to improve your sleep.

Manage the temperature of the bed with Eight’s bed warming feature, to keep your body comfortable and fall asleep faster. There’s a separate set of temperature controls for your partner, so you sleep better together.

Wake up more refreshed each morning using the smart alarm. Eight monitors your sleep patterns to wake you during your lightest sleep stage, giving each day the best start.

Listening to white noise helps you drown out annoying sounds, slow down racing thoughts, and sleep more soundly. Choose from 12 relaxing sounds such as a crackling campfire or underwater waves, and drift off to dreamland.

The Eight integrates with Health app so you can track and compare sleep information from Eight with other data in the health tracking app.

Excellent App, Very Well Thought Out


This app pairs beautifully with the Eightsleep smart mattress cover. Setup of app (and mattress cover) was simple, warming works beautifully (although be aware, in our experience, warming to levels above 3 or 4 can take considerable time. That said, 4 is plenty warm enough with our flannel sheets). The app is clear and very well designed, and very easy to navigate. There is lots of data (toss and turns, breathing rate, even (planned) heart rate!) There are cool "experiments" to try in the "sleep lab," and IFTTT integrations are imminent. Pre-ordered this via Kickstarter several years ago, and-- so far-- it seems to have been worth every bit of the wait!

Update: With the new app, functionality is improved, as is navigation both within the app and the display of data. My first Eight mattress cover lasted for two years before it broke irreparably. However, there was still no product that matched the features and functionality of Eight, so I bought another one. Perhaps the issues I had were early adopter bugs, as my second unit has been going strong so far.

So glad I went with Eight


As someone with a sleep disorder, I am pretty picky when it comes to what I’m looking for in a sleep tracker — many just aren’t that accurate, others are missing features, etc. I ended up getting the mattress cover, and the people here have delivered exactly what I was looking for and more. Initially I had given the redesigned app 4/5 since HealthKit functionality wasn’t enabled (I use it to chart changes in when I’m actually getting sleep) but with that back, I really have no complaints.

A quick note — unlike several other companies, the devs are very responsive and helpful! You can definitely tell they take feedback seriously as they build out the service. After a few years with other trackers spent wondering if the company would ever get around to fixing issues, it’s very refreshing.

Goodbye Sciatic Pain!!!


Our Jupiter+ Mattress has given both me and my wife the best sleep we’ve had in years! After trying mattresses from other “Bed in a Box” companies, Eight Sleep finally gave us the comfort we needed to get a good night’s rest. I’ve suffered from severe sciatica due to a herniated disc in my lower back. Although I couldn’t get full relief until I recently had surgery, my Jupiter+ Mattress definitely gave me some relief that 3 other beds could not. My wife has dealt with neck pain for years and it has also helped her sleep and wake up with no pain. The Sleep Tracker is very beneficial and BY FAR the best sleep tracker we’ve ever tried, all while ACCURATELY providing so much helpful information on each night’s sleep! Thank you Eight Sleep for finally providing us with the best sleep we’ve had in years!!!
