By Eight Sleep, Inc

Open iTunes to buy and download apps.


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.

Customer Reviews

Recent update

Since the app was updated the bed warming schedule feature doesn't work anymore and now you have to keep your phone unlocked to use the alarm! Please fix asap!! **update, they fixed the app quick and easy! Works perfectly again! Great app!!

Vast improvements

Huge improvement over earlier versions and tons of user-requested features. Amazingly responsive app team.


The heart rate and sleep times are inaccurate. I also wear a Fitbit and the two devises are way off on heart rate and restlessness. It doesn't seem capable of distinguishing between myself and hubby, or our pets maybe. It also doesn't heat up or cool down at all and scheduling is a joke. I was so looking forward to utilizing this technology but it seems totally off.
