Sleep Tracking Apps: Do They Really Work?

Sleep tracking apps are a great way to gain insight into your sleep patterns and quality of sleep. These apps can help you understand your sleep habits and make necessary lifestyle changes to improve your sleep. While some apps offer basic sleep tracking features, others provide additional insights such as heart rate and heart rate variability readings. Sleep tracking apps can be used with or without wearable devices, such as the Apple Watch, which provide data on sleep patterns and create graphs to visualise your sleep trends. However, it's important to remember that sleep tracking apps should be used as a supplementary tool and not as a replacement for medical advice or clinical sleep studies.

Sleep tracking apps can help you understand patterns in your sleep habits

Sleep tracking apps are a great way to understand patterns in your sleep habits. These apps use inputs such as sound, heart rate, bedtime, and wake time to provide a snapshot of your sleep duration and quality. By tracking your sleep, you can become more aware of your sleep patterns and make necessary lifestyle changes to improve your sleep quality.

One such app is Sleep Cycle, which is available on iOS and Android devices. Sleep Cycle uses sound analysis to track and improve sleep for its users. It provides detailed analysis of your sleep patterns, detects sounds like snoring and coughing, and offers premium features like relaxing sleep sounds. Sleep Cycle also has a gentle alarm clock feature that wakes you up during your lightest sleep phase, helping you feel more energized in the morning.

Another popular option is SleepScore, which is particularly useful for iPhone users but also works on Android devices. SleepScore offers more detailed sleep-stage data than most other apps and provides a smart alarm that gradually wakes you up, reducing that groggy feeling. The app also allows you to set sleep goals and provides personalized advice to help you achieve those goals.

If you're looking for an app with extra features, Pillow is a great choice. It offers audio recordings, sleep trends, heart rate and oxygen saturation tracking, sleep sounds, a nap mode, bedtime reminders, and personalized insights and tips for better sleep. Pillow provides detailed daily reports and includes audio recordings to help you understand your sleep quality.

It's worth noting that while these apps can provide valuable insights, they are not a replacement for medical advice or a clinical sleep study. If you have concerns about your sleep, it's always best to consult a healthcare professional.

They can be used to track sleep-related breathing disorders

Sleep is essential for health and wellness, and the development of "on a chip" and "smartphone" technologies has led to a surge in affordable, at-home applications and devices that address sleep health and sleep disordered breathing. Sleep-related apps and devices are now offering diagnosis, management, and treatment for a variety of sleep disorders, particularly sleep apnea.

Sleep apnea is a common sleep disorder affecting over 18 million American adults, causing frequent breathing disruptions or very shallow breathing during sleep. It is associated with several health issues, including attention deficit/hyperactivity disorder, high blood pressure, diabetes, heart attack, and stroke. The polysomnography test, the traditional method for diagnosing sleep apnea, is expensive, time-consuming, and labor-intensive. However, smartphone applications and devices now offer more convenient and affordable alternatives for detection and management.

The Apple Watch, for example, has a sleep apnea detection feature that monitors health metrics such as blood oxygen levels, heart rate, and motion. This allows for the detection of potential apnea episodes in real-time and provides valuable data for decision-making. Other apps like SleepScore, Sleep Cycle, and Pillow also offer sleep tracking features, including sleep staging and heart rate variability readings. These apps can help users understand their sleep patterns and make necessary lifestyle changes.

Additionally, the ApneaApp, designed for Android phones, can detect and track breathing movements, separate breathing patterns for multiple people, and estimate total sleep time. It can also detect periodic limb movements and calculate the Apnea-Hypopnea Index, a critical metric for diagnosing sleep apnea. These apps and devices empower individuals to take charge of their sleep health and make informed decisions about their well-being.

They can be used to track sleep cycles and sleep staging

Sleep-tracking apps can be used to track sleep cycles and sleep staging. They can help users understand the patterns in their sleep habits and when they cross the threshold between waking and sleeping. These apps use input such as sound, heart rate, bedtime, and wake time to give a snapshot of the duration and quality of sleep. They can also track sleep-wake stages, or how often one wakes up in the night.

Some apps, like SleepScore, give a "SleepScore" based on an analysis of sleep duration, the amount of time it took the user to fall asleep, light sleep, deep sleep, REM sleep, and wake time. SleepScore also provides more detailed sleep-stage data than most other apps. However, it works better with iPhones than with Android phones. Sleep Cycle, on the other hand, is as compatible with Android models as it is with iPhones. It also has more than a dozen smart-alarm and lulling sounds to choose from. However, it does not provide much detailed sleep-stage data and is less transparent about its research on how well the technology works for tracking sleep.

Other apps, like Pillow, Sleep as Android, and SleepWatch, also provide sleep-tracking features, including sleep staging. Pillow was rated as the best app for extra features, as it offers audio recordings, sleep trends, heart rate and oxygen saturation tracking, sleep sounds, a nap mode, bedtime reminders, and personalized insights and tips to improve sleep. SleepWatch was chosen as the best Apple Watch app because it seamlessly integrates with the watch and automatically collects data, so there is no need to remember to press start before going to sleep. It also analyzes several metrics to give an easy-to-understand snapshot of how well the user slept.

Wearables, such as the Oura Ring, Ultrahuman Ring Air, and Garmin's Epix Pro, can also be used to track sleep cycles and sleep staging. The Oura Ring offers additional insights, including heart rate and heart rate variability (HRV) readings, and has been found to be more accurate than some apps. The Ultrahuman Ring Air provides valuable advice in its accompanying app, and users can review their sleep stages in a chart broken down into awake, REM, light, and deep sleep. Garmin's Epix Pro has Advanced Sleep Monitoring and can track sleep stages, blood oxygen saturation, respiration, and restlessness.

They can be used to track sleep depth and sleep trends

Sleep tracking apps are designed to help users understand patterns in their sleep habits. They can be used to track sleep depth and sleep trends, with some apps offering additional features such as sleep staging, which provides insights into the different stages of sleep, including light sleep, deep sleep, and REM sleep.

Sleep depth refers to the different stages of sleep, ranging from light sleep to deep sleep. During light sleep, individuals can be easily awakened, and this stage is important for mental recovery. Deep sleep, on the other hand, is a period of restorative sleep where the body repairs muscles, boosts the immune system, and consolidates memories. By tracking sleep depth, individuals can gain insights into the quality of their sleep and identify any disruptions or issues that may impact their rest.

Sleep trends involve analyzing sleep patterns over time, often presented in the form of weekly or monthly reports. These trends can help individuals identify long-term patterns, such as the impact of consistent bedtimes or the influence of factors like late-night eating or alcohol consumption on sleep quality. By tracking sleep trends, users can make informed decisions to optimize their sleep habits and overall well-being.

Some apps, like SleepWatch, integrate with wearable devices such as the Apple Watch to collect data on heart rate and movement, providing insights into sleep cycles and an analysis of sleep depth and trends. Pillow, another popular app, offers features such as sleep trend tracking, heart rate monitoring, and oxygen saturation tracking. It provides detailed reports and personalized insights to help improve sleep quality.

It is worth noting that the accuracy of sleep tracking apps can vary, and they may not be suitable for everyone. Some users have reported discrepancies between their actual sleep patterns and the app's recordings, especially in differentiating between light sleep and being awake. However, advancements in technology and algorithms are expected to improve accuracy over time.

They can be used to track sleep alongside other health metrics

Sleep tracking apps often use sound, heart rate, bedtime, and movement data to provide a snapshot of the duration and quality of your sleep. Some apps can also detect sleep-wake stages and sleep-related breathing disorders. While these apps can be useful for understanding your sleep patterns, they should not be used as a replacement for medical advice or a clinical sleep study.

The SleepWatch app, for example, integrates seamlessly with the Apple Watch to automatically collect data and provide an analysis of your sleep. It gives a sleep score and provides insights into the length of sleep, whether you were in light, deep, or disrupted sleep, and variations in heart rate. Other apps like Pillow offer additional features such as audio recordings, sleep trends, oxygen saturation tracking, sleep sounds, a nap mode, bedtime reminders, and personalized insights and tips to improve your sleep.

Sleep tracking apps can also be used in conjunction with wearable devices such as the Apple Watch or the Oura Ring. The Oura Ring, for example, offers additional insights, including heart rate and heart rate variability (HRV) readings, which have been found to be very accurate. These data points, along with oxygen rate and skin temperature readings, could potentially help detect illnesses like COVID-19 before symptoms even begin.

While the Apple Watch's built-in sleep tracking feature has been criticized for being limited, there are many compatible apps that provide more comprehensive sleep-tracking features. For instance, AutoSleep is a popular app for Apple Watch users that automatically tracks sleep and provides insights into sleep quality and consistency.

In addition to sleep tracking, some apps offer tailored advice and personalized tips to help you develop better sleep habits and improve your overall health and well-being. These apps may suggest setting a consistent bedtime or provide recommendations for creating the perfect bedtime conditions with meditation, sleep music, and sleep sounds.
