The best sleep apps can solve a big problem in our lives. Not getting enough shuteye can lead to trouble concentrating, remembering and even operating a vehicle. Adults need 8 hours of sleep each night, but most Americans report an average of 6 hours. Luckily, technology can help. (So can buying the best mattress for your budget.)
On the Android and iOS app store, you'll find a variety of apps — sleep trackers, sleep therapy apps and other tools that aim to help you get a restful night's sleep.
If you're having trouble sleeping through the night, the best sleep apps may be able to make a world of difference for your health.
The best sleep apps for Android and iOS
Sleep Cycle takes the scientific approach to waking you up after a good night's rest. Using your smartphone’s accelerometer and other sensors to record your sleeping habits, the free app uses sleep cycle theory to wake you at just the right time, ensuring you’re getting optimal rest.
Users set a window of time (say a 30-minute stretch) instead of a traditional pinpoint alarm time, and when the app judges that your sleep movement is just right, it will ring the alarm to wake you. In addition to the smart alarm, Sleep Cycle records your sleeping habits for tracking sleep quality over time.
SleepScore takes a different approach to recording your sleep quality than some of the other best sleep apps. It ditches wearables or the need to place your phone on the mattress to record your movement, instead using your phone’s microphone and speakers like a sonar station to record your sleep movements. From this, the app gives you a sleep score and a variety of metrics to gauge your sleep quality.
You can also access tips through SleepScore for how to prepare for better sleep, as well as a smart alarm clock. Premium subscribers get access to longer-term data tracking and more in-depth analysis, as well as a sleep report that you can share with your doctor. A premium subscription costs $5.99 a month.
Note: On Android, the sleep sonar feature is only certified for certain phones like the latest models of the Samsung Galaxy, Note, and Google Pixel.
Headspace is more than just one of the best relaxation apps for mindfulness and guided meditation. The app also has a dedicated sleeping aids section, with soothing guided meditation “Sleepcasts” — wind down exercises designed to prepare your mind for rest, and relaxing music to help give you a good night’s rest. That’s all on top of Headspace’s rich library of free and premium guided meditations.
Free Headspace users get a limited library guided meditations and Sleepcasts, with premium subscribers who pay $12.99 a month getting access to the full library with more than 40 different courses and shorter meditations.

The bright, backlit displays of smartphones and tablets radiate a lot of blue light that's said to mess with your body clock and sleep cycle.

This results in a softer display that's easier on the eyes and less likely to mess with your sleep cycle.
