Pillow Sleep App Review

The Pillow App is a MAC OS application which tracks your sleep. The data it collects helps you gain information about the quality and duration of your sleep, and helps you to improve both.

The app collects motion sensor as well as audio data to monitor and keep track of your sleep phases. Every morning the app presents you with a summary, detailing the quality of your night's sleep, and providing valuable insights about your wake times, the time taken to fall asleep, and how much time you spent in different phases of sleep.

What is Pillow Sleep Tracker?

The Pillow app is a sleep tracking application for iPhone and Apple Watch.

It is currently one of the most popular sleep tracking applications available, boasting an attractive user interface, as well as wide-ranging features that make it stand out from the crowd.

The app analyses your sleep duration and quality, and over time provides you with a comprehensive assessment of your sleep, including suggestions on when to go to bed, and when to wake up in order to feel well rested. Research has shown that an improved quality of sleep not only helps improve your cognitive abilities and mood but is also linked to numerous health benefits.

There are many types of advanced sleep tracking devices in the market today. While some of them are wearable, there are also many totally contactless sleep monitoring gadgets.

How does Pillow Sleep App work?

Pillow sleep tracker collects motion and audio data when you twist and turn at night, and uses it to analyse the quality and duration of your sleep. It asks you to rate your mood after waking up, allowing it to determine what your best possible night's sleep looks like.

Over time, a clear picture of your sleeping habits begins to emerge, which will enable you to make necessary adjustments for an improved night's sleep. To find out more about how the sleep trackers and apps work, I recommend checking out our article, which goes into much greater depth.

The Pillow sleep tracker app is best used on the Apple Watch. Since it is attached to your arm, the app can collect audio and motion data more effectively, giving you more accurate results.

Pillow sleep tracker works by monitoring your sleep. Using the data it acquires, the app makes personalised suggestions which help you to improve the quality of your sleep in the long-run. Not only does this better your mood, and increase your energy levels, but also have many positive health benefits. After all, it's not only the number of hours that we sleep, which counts but also the quality of sleep we have.

The Pillow Lab is a handy feature to help you gain insights into your sleep. It provides a detailed analysis of your sleeping hours, the duration of your sleep sessions, as well as other useful information such as how much time you spend in different phases of sleep, each night.

The app splits our sleep phases into three broad categories:

  • Light sleep
  • Deep sleep
  • REM sleep

The time spent in each of these phases allows you to assess your overall quality of sleep. Based on this information, Pillow sleep app will suggest optimal times for you to go to sleep, and wake up, to make sure you only wake up during the light sleep phase. This helps to feel well-rested and energetic in the morning.

Have you ever wondered what you sound like when you snore? What about whether or not you sleep talk? Pillow sleep tracker app can help you find out, by recording all audio above a certain volume threshold while you sleep.

Important features

The Pillow app comes with many handy features. Some of these include:

  • Heart rate analysis - displays a detailed graph of your heart rate throughout the night

User opinions

Users of the Pillow sleep tracker app seem to be very happy with it. It has over 30,000 5-star ratings on the app store and generally appears to fulfil expectations. Most online reviews are positive, and there are no specific areas users complain about when rating the app.

In fact, many online reviews refer to the Pillow as the best sleep tracking app currently on the market. This is supported but the fact that it has a 4.4-star rating in the App Store.

However, numerous users have complained that the latest update (released on 19th of June) has been causing problems. Prospectively this will be fixed very soon.


In conclusion, the Pillow sleep tracker app is the best sleep monitoring app currently on the market. It gives users free access to all basic features and provides them with detailed insights into their sleep quality.

Its user-friendly interface makes the app attractive and easy to use. Sleep data is very informative and displayed in easy-to-understand way.

Unfortunately, the app is exclusively available for MAC OS, leaving Android users frustrated.

Although the latest update seems to have caused users problems, this will likely be fixed soon.
