Sleep-tracking apps are a great way to understand your sleep patterns and sleep quality. These apps can help you understand when you cross the threshold between waking and sleeping, and what happens in between. They can also help you set sleep goals and provide advice on how to achieve them. There are many options available for sleep-tracking, including standalone devices, wearables, and built-in features in fitness trackers and smartwatches. However, apps are a popular choice because they are accessible and relatively inexpensive. Some popular sleep-tracking apps include SleepScore, Sleep Cycle, Sleep as Android, and Pillow. These apps can help you track your sleep by using your phone's built-in accelerometer, sonar technology, or microphone and speaker to judge how well you're sleeping.

What You'll Learn
Sonar technology
So, how does sonar technology work for sleep tracking? When you place your phone on a nightstand near your bed, the app emits inaudible sound waves or sonar signals from your phone's speakers. These signals bounce off your body, particularly your chest, as you breathe and move during sleep. The phone's microphone then picks up these reflected sound waves, and advanced algorithms interpret their shape and movement.
By analyzing the changes in the sound waves, the app can measure your breathing rate and body movement. This information is crucial for understanding your sleep patterns and identifying the different stages of sleep, such as light sleep, deep sleep, and REM sleep. Sonar technology is precise enough to distinguish between the various sleep stages and even detect sleep disorders like sleep apnea.
It is important to note that the effectiveness of sonar-based sleep tracking depends on the proper positioning of your phone. The phone should be placed at a height close to your chest, and any interfering devices, such as fans or speakers, should be at least six feet away to ensure accurate results. Additionally, the frequencies used in sonar sleep tracking apps are considered safe and fall within the range of everyday sound waves we encounter.

Sleep tracking apps
There are several sleep tracking apps available, each with its own unique features and benefits. Here are some of the most popular ones:
- SleepScore: This app uses sonar technology to measure your sleep through your breath and the movements your body makes during the night. It provides information on sleep stages in the form of a score between 0 and 100, which can be useful for tracking your sleep progress. SleepScore also offers easy-to-understand graphs and additional features to help you improve your sleep. It works better with iPhones than with Android phones.
- Sleep Cycle: This is a comprehensive sleep tracking app that provides detailed stats and sleep graphs to help you understand your sleep patterns. It uses your phone's sound recorder to analyze sounds and track your sleep. Sleep Cycle can be placed on the floor or your bedside table, offering flexibility in use. It is compatible with both Android and iPhone models.
- Google Fit: This app allows you to sync your data from other sleep-tracking apps and devices, providing charts and detailed information about your sleep. You can review your sleep time frames, sleep quality, room temperature, respiratory rate, and more. Google Nest Hub users can also access in-progress sleep session overviews.
It's important to note that while these apps can provide valuable insights, they are not a replacement for professional medical advice. If you have concerns about a sleep disorder or persistent sleep issues, it's recommended to consult a healthcare professional.

Wearables
When choosing a wearable sleep tracker, it is important to consider factors such as comfort, battery life, and accuracy. Some wearables, like the Google Pixel Watch 2, offer a lightweight design for a more comfortable sleep. However, its 24-hour battery life may not be as competitive as other smartwatches. In terms of accuracy, while no app offers perfectly objective sleep analysis, some wearables, like the Oura Ring, are considered to provide impressive results.
To utilize a wearable for sleep tracking, you typically need to connect it to a companion app on your smartphone. This allows you to access and review your sleep data, set preferences, and even sync with other health platforms to consolidate your health information.
In summary, wearables offer a convenient way to track your sleep patterns, heart rate, and other health metrics. They provide insights that can help you understand your sleep quality and make improvements. When choosing a wearable, consider comfort, battery life, accuracy, and the accompanying app's features to ensure it suits your needs.
