Though it’s become cliche, the phrase “there’s an app for that” becomes more accurate by the day. As smartphones are increasingly more powerful and feature-packed, app developers continue to innovate to deliver a huge range of offerings.

Sleep apps have undergone dramatic expansion and improvement. These apps can make it easier to fall asleep, wake up, and monitor your sleep trends.

But anyone who’s used an app store can tell you, the sheer number of apps can be burdensome to sort through. You might not have the time to go through them all to find the good and the bad.

Our guide to the best sleep apps does the work for you and introduces you to the most important categories of sleep apps and our top picks in each of those categories.


Sleep Tracking Apps

How Do Sleep Tracking Apps Work?

Sleep tracking apps have several avenues for collecting data.

  • The accelerometer in your phone can be used to track motion.
  • Optical heart rate monitoring analyzes the way light reflects off your skin to determine blood flow and heart rate.
  • Sonar can be used to detect movement, including the rise and fall of your chest from breathing.
  • Noise tracking can give details about movement and activity.

The app analyzes this type of data taken in by the phone to draw conclusions about your sleep. Common metrics relate to the total time you spent sleeping, the quality of your sleep, and time spent in different sleep stages.

Sleep tracking apps make this information available in a visual dashboard and may offer tips for improving your metrics.

It is important to remember that the accuracy of sleep tracking apps is still up for debate. The data collection and analysis methodology is new and has not undergone extensive long-term study. For this reason, it’s best to always consider the big picture and to raise any serious sleep concerns with a doctor.

Why Use a Sleep Tracking App?

A sleep tracking app can be useful for learning about the patterns of your sleep. Though not perfectly accurate, these apps can assist you in understanding how much sleep you’re getting and whether you’re restless during the night.

A sleep tracking app may be able to identify sleeping problems and in some cases offer tips that you can use to address those issues.

Many sleep tracking apps include smart alarms that wake you up according to your progression through different sleep stages. This can reduce the odds of waking up groggy or disoriented.

What Are The Best Sleep Tracking Apps?

Numerous sleep tracking apps are available for both Android and Apple operating systems. For their tracking tools and interface, the following are our top picks for the best sleep tracking apps.


  • Availability: iOS, Android
  • Price: Free With In-App Purchases; $50 yearly subscription for Premium

SleepScore uses sound tracking and sonar motion detection to evaluate your sleep without any contact with your body: it works with your phone near the bed, such as on a nightstand. The app’s algorithm creates a simple, easy-to-understand score from 1-100 for each night’s sleep while allowing you to drill down to more detailed metrics of your sleep.

The Premium version, which costs $50 for a year, provides more robust features and access to long-term tracking, goal-setting, and sleep advice. A PDF sleep report can be generated by the app to share with your doctor if you have prolonged sleep issues.

Sleep as Android

  • Availability: Android
  • Price: Free With Ads / In-App Purchases; $5.49 for Ad-Free, Premium version

Sleep As Android uses the accelerometer, sonar, sound recording, and optional integration with heart rate monitors to deliver metrics about your sleep. Motion tracking is most effective if your phone is kept on your mattress, but other tools, like sonar, can work on a nightstand.

With this data, Sleep As Android tracks your sleep cycle and has a smart alarm to wake you up at the appropriate point. It records and analyzes snoring to help indicate if you may have an issue with sleep apnea.

The app can be used for free with ads, but to unlock all the features and eliminate ads requires a one-time $5.49 purchase.

Sleep Cycle

  • Availability: iOS, Android
  • Price: Free With In-App Purchases; One-Year Subscription for $29.99

With either mode, Sleep Cycle evaluates the data to track your time in each sleep stage. Its smart alarm then wakes you up based on indications that you are in the lighter phases of the sleep cycle.

The app provides graphs documenting your sleep, and the Premium version offers long-term sleep tracking, tips to improve sleep, online backup, and expanded features for easing into and out of sleep.

White Noise Apps

How Do White Noise Apps Work?

One important aspect of sleep hygiene is having a sleep environment that makes it easy to doze off. Unfortunately, noise, whether from the street outside, from a neighbor, or even from a creaky old house, can hinder our best efforts to fall asleep.

A white noise app creates a low-level sound that fills the background and minimizes those other noises. While you hear the noise produced by the app, it is consistent and non-intrusive, creating a sleep setting with fewer disruptions.

The sounds from a white noise app can be varied. Most apps offer several types of sounds to select from. These can be fan-like whirring noises, nature sounds, calming music, and many others.

Why Use a White Noise App?

The point of a white noise app is to create a stable background sound that drowns out other noises that might bother you.

White noise machines perform the same function, but these devices take up space and can be expensive. White noise machines can be harder to travel with as well. For these reasons, many people benefit from a white noise app on their smartphone.

What Are the Best White Noise Apps?


  • Availability: iOS, Android
  • Price: Free With In-App Purchases; $8.99 for expanded sound options

Each sound comes with custom generators, which are a series of sliders that allow you to adjust the characteristics of the sound to best fit your needs and preferences.

Blue Light Filtering Apps

How Do Blue Light Filtering Apps Work?

Blue light is a spectrum of light produced at higher levels by devices such as mobile phones and laptops. Unfortunately, exposure to blue light in the evening can interrupt our circadian rhythm that helps regulate our sleep.

Specifically, blue light can suppress the production of melatonin, a hormone that the body produces to help ease us comfortably into sleep.

A blue light filtering app reduces the amount of blue light that is produced by your phone. It is designed to be used in the evening and closer to bedtime.

The iOS used on Apple products now comes with a standard “Night Shift” mode that works as a blue light filter. Some Android devices may have this as a built-in feature.

Why Use a Blue Light Filtering App?

Many experts recommend reducing our exposure to blue light before bed. Often, they advise not using your phone for an hour or more before bedtime.

For many people, though, it may not be feasible or convenient to fully stop using their phone in the evening. For that reason, a blue light filter can permit use of a phone without as much harmful exposure to blue light.

If you don’t have iOS with Night Shift mode or an Android phone with a pre-installed blue light filter, a blue light filtering app is generally the easiest and most cost-effective means of decreasing your blue light before bed.

Snoring Tracking Apps

How Do Snoring Tracking Apps Work?

Snoring tracking apps record you during the night to detect the severity of your snoring. They often can allow you to listen to a recording of your snoring.

Most of these apps utilize algorithms to help you understand how often you snore, the degree of that snoring, and what that illustrates with regard to broader trends in your sleep.

Why Use a Snoring Tracking App?

Because it happens while you’re asleep, it can be hard to know how much you snore or if you’re even snoring at all. A snoring tracking app fills in this information gap.

Chronic snoring can be a sign of other problems, including obstructive sleep apnea, and a snoring tracking app may be able to help identify if you need to talk with your doctor about snoring.
