Sleep Tracker Apps: Effective Or Just A Fad?

Sleep tracker apps have become increasingly popular as more people are interested in understanding their sleep patterns to improve their sleep quality. These apps use a combination of sonar technology, advanced algorithms, and built-in accelerometers to track sleep patterns, including sleep duration, quality, and the different phases of sleep. While some people find these apps useful for reflecting on their sleep habits, others question their accuracy and potential impact on sleep due to the overwhelming amount of data and graphs provided. Additionally, concerns have been raised about the indirect measurement of sleep through inactivity or movement, which may not capture the nuances of sleep stages accurately. As a result, it is recommended to take the insights from sleep tracker apps with a grain of salt and consider combining them with other methods, such as sleep laboratory studies, for a comprehensive understanding of one's sleep.

Sleep tracker apps' accuracy

Sleep-tracking apps have become increasingly popular, with one source estimating that one in three Americans has used a sleep-tracking device. While these apps can provide a wealth of information about your sleep habits, it's important to question their accuracy.

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. Additionally, the accuracy of sleep-tracking apps improves the longer you use them, as they collect more data over time. However, it's worth noting that two apps using the same technology can still yield very different sleep reports.

Sleep-tracking apps use various methods to track your sleep. Some apps, like Sleep.com, use sonar technology and advanced algorithms to determine the amount of time spent awake and asleep, and even break down that time into different sleep stages. Other apps rely on optical heart-rate monitoring, where tiny LEDs in the band shine a light through your skin to capture blood flow. These apps combine this information with your movement data to deliver your sleep report.

The accuracy of these apps has been called into question by some users and experts. One source suggests that sleep-tracking apps can only make an “educated guess" about your sleep stages and that they are not worth your time. Another source mentions that sleep-tracking apps don't directly measure sleep but instead estimate it by measuring inactivity. To get truly accurate data about your sleep habits, you would need to undergo a medical sleep study that monitors brain waves.

However, it's important to note that advancements in technology have made it possible for consumers to access accurate information about their sleep patterns from the comfort of their own homes. Commercial sleep trackers, such as wearables, offer advantages over traditional actigraphy or polysomnography methods used in labs. These devices are easily accessible, provide extra data like heart rate and oxygen levels, and offer information directly to the user. According to multiple studies, commercial sleep trackers perform as well as, or even better than, actigraphy.

While the accuracy of sleep-tracking apps may still leave something to be desired, they can be useful tools for monitoring your sleep habits and making adjustments to improve your sleep quality.

The pros and cons of using a sleep tracker app

Sleep tracker apps are a nascent technology that can be a useful tool to gain insight into your sleep patterns. They can help you understand your sleep patterns and make changes to improve your sleep. However, they have limitations and should be used only as a general guide.

The Pros

Sleep tracker apps are easily accessible, as they are available on smartphones and can be used without any additional devices. They can record and provide an extensive amount of data about your sleep, such as the time you fell asleep and woke up, your sleep regularity, and sleep duration. This data can help you understand how your sleep patterns affect your daily life, including your mood and productivity.

Sleep tracker apps vs. sleep tracker devices

Sleep tracking apps and devices have become increasingly popular, with many options available to consumers. Both sleep tracking apps and devices can help users gain insight into their sleep patterns and develop better sleep habits. However, there are some key differences between the two in terms of functionality, accuracy, convenience, and cost.

Functionality-wise, sleep tracking apps often use input such as sound, heart rate, bedtime, and wake time to provide a snapshot of sleep duration and quality. Some apps can also detect sleep-wake stages and sleep-related breathing disorders. On the other hand, sleep tracking devices typically use built-in accelerometers and software to track sleep patterns over time. Devices like smartwatches or fitness trackers collect data on heart rate, heart rate variability, movement, breaths per minute, and skin temperature. Some devices also have advanced sleep monitoring features, such as tracking blood oxygen saturation and restlessness.

In terms of accuracy, sleep tracking devices may have an edge over apps. Devices worn on the wrist or clipped to clothing reduce the chance of movement by a pet or bedmate being registered, potentially providing more accurate data. Additionally, a 2017 study found that a Fitbit device detected sleep onset with 96% accuracy, light sleep with 81% accuracy, deep sleep with 49% accuracy, and REM sleep with 74% accuracy. While some apps claim high accuracy, there are mixed reviews, with some users questioning the accuracy of their measurements.

When it comes to convenience, sleep tracking apps have the advantage of being easily accessible on smartphones, eliminating the need for additional devices. However, sleep tracking devices offer a more seamless experience as they are designed to be worn and often provide more detailed insights without requiring the user to input data manually.

Ultimately, the choice between an app or a device depends on individual preferences, needs, and budget.

Sleep tracking and health

Sleep tracking apps have become increasingly popular in recent years, with many people turning to technology to help them understand their sleep patterns and improve their sleep quality. These apps can be a useful tool for gaining insight into your sleep habits and making informed decisions about your sleep hygiene. However, it's important to approach sleep tracking with a critical eye, weighing the benefits against potential drawbacks.

One of the main advantages of sleep tracking apps is their convenience and accessibility. Most sleep tracker apps use your smartphone's microphone and speaker to record various sounds during the night, including your movements and sleep interruptions. This data can provide a general overview of your sleep patterns, such as the time you fell asleep, sleep duration, sleep regularity, and interruptions during the night. Some apps also measure ambient noise to determine if your sleeping environment is optimal. This information can be helpful in making simple adjustments to your sleep habits and environment to promote better sleep.

However, it's important to recognize the limitations of sleep tracking apps. While they can estimate sleep patterns, they don't directly measure sleep. Instead, they often rely on inactivity as a surrogate for estimating sleep. This means that the data provided may not always be accurate, especially when differentiating between the various stages of sleep. For example, sleep trackers that rely solely on movement detection may not accurately distinguish between the different phases of sleep, such as REM sleep and deep sleep, which involve varying levels of muscle paralysis.

Additionally, the sheer amount of data and analytics provided by sleep tracking apps can sometimes do more harm than good. The abundance of features, graphs, and records can be overwhelming and may even contribute to heightened anxiety or obsession over sleep. This is particularly true if the data provided is inaccurate, leading to misinterpretations of your actual sleep quality. Therefore, it's recommended to use sleep tracker apps as a general guide rather than an absolute authority on your sleep.

Despite their limitations, sleep tracking apps can be a valuable tool for those who want to gain preliminary insights into their sleep habits without undergoing a full medical sleep study. They can help identify patterns and trends in your sleep, such as the ideal time to go to bed, the impact of caffeine consumption, or the influence of environmental factors. This information can then be used to make informed decisions and adjustments to improve your sleep hygiene and overall sleep quality.
