Sleep Tracking Apps: How Do They Work?

Sleep-tracking apps are a great way to understand your sleep patterns and habits. These apps can help you understand when you cross the threshold between waking and sleeping, and what happens in between. They can track, record, and monitor everything you do during your sleep, including snoring, sleep talking, and coughing. They can also monitor your heart rate and record audio during your sleep. Some apps can even detect if there are two or more people sleeping in the same bed and ensure that the tracking is correct. Sleep-tracking apps can be a fun way to understand your sleep better and make improvements to your sleep hygiene.

How do sleep tracking apps work?

Sleep-tracking apps can help you understand when you transition between being awake and falling asleep, and what happens in between. They can also help you improve your sleep hygiene by providing recommendations and strategies.

Sleep-tracking apps can be used in conjunction with wearables, such as smartwatches, fitness trackers, or rings, to monitor your sleep cycles. Alternatively, some apps can be used independently on your smartphone. Some apps require you to place your phone on your nightstand or the floor nearby, while others can be placed under your pillow or mattress. There are also apps that can be used with accessories, such as the Apple Watch, which you wear while sleeping.

Sleep-tracking apps use various methods to track your sleep. Some use sound analysis to identify sleep states, using your phone's microphone to record sounds such as snoring, sleep talking, or coughing. Others use motion monitoring to detect when you toss and turn or wake up in the middle of the night. Some apps, like Sleep Score, measure your heart rate to check your sleep quality. The app also provides an option to set an alarm when your sleep quality is low, so you can wake up when you are well-rested.

In addition to tracking your sleep, some apps offer features such as smart alarms that wake you up during your lightest sleep phase, relaxing sounds or music to help you fall asleep, and sleep stories or guides. Some apps also provide detailed sleep statistics and graphs, allowing you to visualize your sleep patterns.

It is important to note that sleep-tracking apps may not provide advice on improving sleep habits based solely on the data collected. However, they can help you identify trends and patterns to make informed decisions about your sleep hygiene.

What are the best sleep tracking apps?

Sleep tracking apps can help you understand your sleep habits and patterns. They can track your sleep-wake stages, sleep-related breathing disorders, heart rate, body motions, sleep talking, snoring, and more.

SleepScore is a popular sleep tracking app that works well with iPhones and, to a lesser extent, Android phones. It allows you to set sleep goals and provides detailed sleep-stage data and actionable advice for achieving your goals. It also has a smart alarm that wakes you up slowly. The free version offers general sleep advice and a record of your sleep for seven days at a time. The premium version costs $50 a year or $6 per month and provides more advanced features. SleepScore also sells accessories that can analyze the light and sound in your room to further improve sleep analysis.

Sleep Cycle is another highly-rated sleep tracking app that is compatible with both Android and iOS devices. It uses sound analysis to identify sleep states and tracks your movements in bed. It also has a smart alarm clock that wakes you up during your light sleep phase. The app provides detailed sleep statistics and daily sleep graphs, as well as a sleep aid feature with sleep stories, relaxation guides, and calm sleep sounds.

For Apple Watch users, AutoSleep is a good option. It generates scores for your sleep quality and consistency and correctly flags nights with poor or good sleep. It is also one of the only non-subscription sleep tracking apps. Pillow is another Apple Watch app that monitors your heart rate and records audio during your sleep. It provides a complete insight into your sleep cycle through beautiful visualization charts.

If you are looking for an app with a holistic approach to your sleeping patterns, MotionX 24/7 is a good option. It has reliable sleep tracking technology and a smart alarm that plays soft music 30 minutes before your alarm and adjusts alarms according to your behavior, patterns, and movements.

Finally, Sleep Genius is an app developed by authorities in neuroscience, sleep, and music to help you relax and sleep better. It has various customizable programs, including sleep patterns, cycle alarms, relaxation programs, and power naps.

How do sleep tracking apps improve sleep?

Sleep-tracking apps are designed to help users understand the threshold between waking and sleeping, and what happens in between. They can help users improve their sleep quality and gain knowledge about the best sleep times and duration. These apps can also help users wake up at the right time, and some even offer a holistic approach to sleeping patterns.

Sleep-tracking apps can improve sleep quality by providing detailed sleep statistics and daily sleep graphs, as well as sleep analysis. They can also help users set sleep goals and give advice on how to reach them. Some apps provide information on improving sleep hygiene, such as avoiding heavy or high-acidity meals, alcohol, and screen time before bed.

Some apps, like Sleep Cycle, use sound analysis to identify sleep states and track movements in bed. This can help users understand their sleeping patterns and wake up feeling more refreshed. Sleep Cycle also has an education library with quick, podcast-like recordings on various sleep-related topics, as well as exercises for daytime relaxation to help prepare for better sleep.

Other apps, like SleepScore, offer more detailed sleep-stage data and a smart alarm that wakes users up slowly, reducing grogginess. SleepScore also has a Doctor Report feature that prints 30 days' worth of data that can be taken to a doctor's appointment.

Some apps, like the Oura Ring, require a monthly membership to access all data and insights. This membership includes unlimited sleep history tracking, charts to visualize sleep patterns, and a readiness score. After a few weeks, the Oura app learns sleep patterns and gives personalized tips and reminders, like when to start winding down for bed to improve sleep quality.

What data do sleep tracking apps collect?

Sleep-tracking apps can help you understand when you transition from being awake to falling asleep and what occurs during your sleep. They can also help you set and achieve sleep goals. However, it is important to note that these apps do not directly measure sleep. Instead, they estimate sleep by tracking inactivity.

Sleep-tracking apps collect a range of data to analyse your sleep patterns and provide recommendations for improvement. This includes tracking the time you become inactive to record when you fall asleep and when you wake up. They can also detect interrupted sleep, such as tossing and turning, and track sleep phases to time your alarm to less disruptive phases. Some apps can also detect snoring, sleep talking, coughing, and other sounds.

Some apps, like SleepScore, allow you to input lifestyle factors such as caffeine intake, meal times, and stress levels, which can impact your sleep. This data is used to provide advice on improving sleep hygiene, such as avoiding heavy meals or screen time before bed. The premium version of SleepScore offers features like a "Doctor Report" that provides 30 days' worth of data that can be shared with a healthcare provider.

Other apps, like Pillow, integrate with Apple Health to exchange sleep analysis and heart rate data. They may also offer additional features like a mood diary that syncs to the cloud, allowing you to reflect on how your daily moods relate to your sleep patterns. Some apps, like MotionX 24/7, use AI to learn your behaviour, patterns, and movements, adjusting alarms accordingly to wake you during lighter sleep phases.

Wearable devices, such as smartwatches and rings, can also be used to track sleep. For example, the Apple Watch can track sleep through its built-in sleep-tracking feature or via compatible apps like Pillow and Sleep Cycle. The Oura Ring is another example of a wearable that collects sleep data, although it has been noted to be less useful for fitness tracking during active periods.

How accurate are sleep tracking apps?

Sleep-tracking apps are a great way to gain insight into your sleep patterns and habits. They can help you understand when you transition between the various stages of sleep and what happens in between. However, it is important to note that the accuracy of these apps varies.

The accuracy of sleep-tracking apps depends on two main factors: how well the app measures the data and how well the company's algorithm interprets that data. The more data the app collects, the more helpful it can become over time. Some apps, like SleepScore, use sonar technology to measure breathing, movement, and sounds. It then develops a sleep score and curates goals to help you improve your sleep. SleepScore also offers a "Doctor Report" feature that prints out 30 days' worth of data that you can take to your doctor's appointment. Other apps, like Sleep Cycle, use sound analysis to identify sleep states, tracking your movements in bed and detecting snoring, sleep talking, coughing, and other sounds. It also provides a detailed analysis of your bedtime patterns and access to premium features such as relaxing sleep sounds and a story library.

While these apps can provide valuable insights, it is important to remember that they are not a substitute for medical advice. If you have concerns about the quality of your sleep or are experiencing sleep-related issues, it is recommended to consult a health practitioner. Additionally, the accuracy of these apps can be affected by various factors, such as the technology used, the user's environment, and individual differences in sleep patterns. As a result, two apps using the same technology can yield very different sleep reports.

In conclusion, while sleep-tracking apps can provide useful information about your sleep patterns, it is important to take their results with a grain of salt. They can help you recognize trends and patterns, but for exact data about your sleep habits, a medical sleep study that monitors brain waves would be necessary.
