If you are waking up tired or are concerned about the quality of your sleep, there are many apps to help. Sleep tracker apps analyze your sounds, movement, and behaviors as you sleep to give you a clear snapshot of the duration and quality of your sleep. These apps can also help you determine how much time you spend in Rapid Eye Movement (REM) sleep and how many times you are disturbed throughout the night.

The best sleep tracker apps use input such as sound, heart rate, bedtime, or wake time to give you an accurate picture of your night. Many apps use data from wearable devices such as an Apple Watch to provide you with a sleep score and create graphs that show changes over time. Some apps allow you to export your data so you can share it with your health care professional to get assistance with your sleep issues. We looked at several sleep tracker apps to find the best ones to help you identify issues and improve your sleep quality.

Best Sleep Apps of 2021

Best Overall : SleepScore


SleepScore

SleepScore

Why We Chose It: SleepScore is our best overall app as it is available for iOS and Android and offers many great features to track and improve your sleep.

What We Like
  • Uses sonar technology to track your sleep

  • Syncs with wearables such as Apple Watch

  • Clear analysis of sleep patterns and easy-to-understand sleep score

  • Measures light and noise level in the bedroom to determine optimal conditions for sleep

What We Don’t Like
  • You must start and stop the tracker for accurate tracking

  • Reviews state it does not function as well on Android-powered devices compared to iOS

As the most advanced sleep tracker on this list, SleepScore uses sonar technology to measure sleep habits from your nightstand. ResMed, the developer of SleepScore, has studied sleep for over a decade to provide expert advice and sleep insights. The app sends sonar waves from your phone to measure your breathing and any sounds, which allow it to track light, deep, and REM sleep and identify when you wake up during the night. The app formulates a sleep score to attach an objective number to your sleep quality to help with setting goals for better sleep. To use the sonar technology, you must leave your phone plugged in, above mattress level, and with the base of the phone pointed toward you (which may not be possible depending on your bedroom setup).

SleepScore is available on iOS and Android. The free version of this app includes many features such as sleep tracking, smart alarms, goal setting, light and sound monitoring, bedtime reminders, sleep scores, and a seven-day sleep history. SleepScore premium costs $7.99 a month or $49.99 a year after a one-week free trial. This premium membership gives you access to unlimited sleep history tracking, charts to visualize your sleep patterns, sleep coaching, and a doctor’s report that will point out concerns in your sleep that you can bring with you to your medical professional. Overall, if you’re looking for a comprehensive sleep tracker app, SleepScore has all the features you need to fully understand your sleep patterns.

Best for Apple Watch : SleepWatch


SleepWatch

SleepWatch

Why We Chose It: We chose SleepWatch as the best Apple Watch app because it automatically collects data from your watch and analyzes several different metrics to give you a well-rounded picture of how well you slept.

What We Like
  • Information is presented in a clear, concise way

  • Graphs are easy to understand

  • All metrics have definitions of what they mean and why it is important

What We Don’t Like
  • Some analysis provided is very technical and difficult to understand

  • Bell curve comparison to other users is not necessarily a helpful metric

  • Does not track REM sleep

SleepWatch by BodyMatter automatically tracks sleep from information collected by your Apple Watch. This is the easiest app to use with this device, as it collects everything you need without you having to input your data. We liked that it gives you a sleep score to measure how well you slept and provides you with an in-depth analysis based on length of sleep, whether you were in light, deep, or disrupted sleep, and variations in heart rate throughout the night. All you need to do is wear your Apple Watch to bed and the app will do the rest. There is also the option to track behaviors such as late-night eating or alcohol consumption to help identify if certain behaviors impact the quality of your sleep.

SleepWatch has over 283,000 reviews and the average rating on the App Store is 4.7 stars, as of September 2021. Memberships cost $3.99 a month or $29.99 a year, making it affordable for anyone wanting a more detailed interpretation of their sleep patterns. It is only available on iOS and works best with an Apple Watch, although it can be used with another Apple device. SleepWatch offers a one-week free trial.

Best Free : Sleep++


SleepWatch

SleepWatch

Why We Chose It: Sleep++ is a free app that tracks basic sleep patterns with an uncluttered and simple design.

What We Like
  • Free

  • Simple measurements of restful and restless sleep as well as awake time

  • Automatically tracks sleep when wearing an Apple Watch

What We Don’t Like
  • Only available on iOS

  • Layout of the app is not appealing

  • Lacks additional insights into sleep quality compared to other sleep tracking apps

Sleep ++ by Cross Forward Consulting is perfect for basic sleep tracking. When used with an Apple Watch, it will automatically track sleep and provides you with a clear report of sleep quality. We found that the app interface is fairly basic and difficult to interpret at first glance. If you do not have an Apple Watch, you must manually input when you fell asleep and when you woke up.

The app provides you with daily and average sleep times, how many hours were restful sleep, and the number of minutes you were awake. It also gives you a sleep duration score so you can track changes over time. It lacks features available on other sleep tracker apps such as smart alarms or light and sound monitoring, and if you are trying to use this app without an Apple Watch, having to manually input data could lead to inaccurate results. Sleep++ is only available for iOS and has an average rating of 4.2 stars in the App Store as of September 2021. If you’re looking for a free app that provides a simple overview of how long and restful your sleep is, then this is a good option.

Best for Extra Features : Pillow


Pillow

 Pillow

Why We Chose It: We chose Pillow as the best app for extra features as it offers audio recordings, sleep trends, personalized insights, and tips to improve your sleep.

What We Like
  • The audio recording feature records when you snore, cough, or talk in your sleep

  • Personalized insights and tips to improve your sleep

  • Displays REM, light, and deep sleep as well as awake time in a simple color-coded graph

What We Don’t Like
  • Only available on iOS

  • Best results when paired with an Apple Watch

  • Reviews state there is a recent reduction in the app functionality

Pillow, the sleep app by NeyBox Digital Ltd., has an average rating of 4.3 stars on the App Store and can be used to automatically track sleep. This sleep tracker app is compatible with an Apple Watch, but it can also be used in manual mode. We liked that this app offers the option of enabling audio recordings while you sleep, which is helpful for those who suspect that snoring or talking in their sleep is disrupting their sleep cycle. The sleep analysis includes a sleep cycle diagram and heart rate analysis, and it displays trends over time. Pillow regularly updates sleep tips to help you fall asleep and stay asleep and personalizes your insights over time.

Pillow is only available for iOS and costs $4.99 a month, $12.99 for three months, and $39.99 for a year. A one-week free trial is available. It is only available on iOS, but it syncs with the Apple Health app so you can have all your data in one place. If you’re using it without an Apple Watch, you must input what time you fall asleep and what time you wake up, which can lead to inaccurate measurements.

Best Versatile App : Sleep Cycle


Sleep Cycle

 Sleep Cycle

Why We Chose It: We chose Sleep Cycle as the best versatile app as it is available on iOS, Android, and Huawei.

What We Like
  • Overlay of audio recordings on the sleep cycle graph for better interpretation

  • Able to identify a variety of different sounds, including coughing, talking, snoring, and a baby fussing

What We Don’t Like
  • Lack of in-depth analysis of sleep compared to other apps

  • Need to manually start and stop sleep tracking

  • Poor descriptions of different tracking metrics

Sleep Cycle by Sleep Cycle AB gives you a simplified look at sleep patterns by analyzing audio recordings of snoring, talking, coughing, and other sounds. This app tracks your sleep cycle graphically and overlays audio recordings to help identify what is going on during different periods of sleep.

It has an average rating of 4.7 stars on the App Store and 4.5 stars on Google Play, as of September 2021. Sleep Cycle offers sleep statistics and can identify both short- and long-term trends. No equipment or fitness wearables are needed; all you need to do is have your phone beside your bed. The app must be turned on before going to bed, and since it uses sound analysis to identify sleep states, there is the potential for error if you sleep with others in the room. You do need to start and stop the sleep timer manually, which can be problematic if you forget to do this regularly.

Sleep Cycle costs $9.99 per month or $39.99 per year and, like other apps, it offers a one-week free trial. This app is extremely versatile as it can be used on Android, iOS, and Huawei.

Best for Android : PrimeNap


PrimeNap

PrimeNap

Why We chose It: PrimeNap is a sleep app that’s specifically made to work on Android-powered mobile phones.

What We Like
  • Features a sleep debt analysis chart

  • Includes a dream journal

  • No subscription required

What We Don’t Like
  • Interface is hard to navigate

PrimeNap is a free sleep tracker that will track your sleep and provide you with useful data and charts that analyze your sleep length and quality. Like other sleep apps, it records your sleep based on movement and can be used for nighttime sleep and mid-day naps. It includes some unique features such as smart alarms, a dream journal, and sleep sounds to play while you rest.

The app is available on Android and has many of the features found in more expensive apps. We liked that it can be used in airplane mode and offers you detailed data on how long you spend in different sleep cycles. You can also export your data to share with others. The app is designed to show you sleep patterns to help you improve your sleep and identify where problems lie. 

Reviews online state that smart alarms can be confusing and aren’t always accurate. This app is relatively new and is rated 3.7 out of 5 on Google Play. It does not automatically track your sleep, so you must remember to turn it on and off for accurate measurements. Overall, PrimeNap is a great free Android app for those looking to analyze their sleep.

Final Verdict

The best sleep tracking apps give you measurable data on how long and how well you slept and can be used with or without a wearable fitness device. Apps that are used on a wearable can automatically track your sleep, but non-wearable users have to input when they fall asleep and wake up; this is not ideal, but it is the most realistic option for many people. The apps outlined in our roundup provide options for anyone looking to track their sleep and develop a plan to improve it.
