The Sleep Cycle app uses sound analysis to track sleep
The Sleep Cycle app is a versatile choice for those interested in the science of sleep. It uses sound analysis to track sleep and identify sleep states. The app relies on sensors and algorithms to detect when the user falls asleep and their sleep patterns. The user places their phone near their bed, and the microphone in the device listens to sounds such as breathing, movement, snoring, coughing, sleep talking, and ambient noise. The app then analyses the data and provides findings that correlate with the user's habits and external factors, including their surroundings.
Sleep Cycle's Who's Snoring? feature can differentiate between snoring sounds from two or more people sharing a bedroom, providing a more accurate picture of the user's sleep and overall health. The app also provides a full breakdown of all sleep stages, Awake, Light, Deep, and Dream (REM), and allows users to compare their sleep patterns to world sleep statistics.
Sleep Cycle offers a range of premium features such as relaxing music, sleep stories, and meditations, and gentle wake-up tones. It also provides a graph of the user's sleep cycle and allows them to review and delete recordings. The app compares the user's sleep data to that of others in their vicinity or nation and provides a map of areas where coughing is heavy. Additionally, it offers long-term trends on sleep patterns and allows users to add sleep notes to see how events such as drinking coffee, stress, working out, or eating late affect their sleep quality.
The app aims to provide powerful insights to help users improve their sleep and make positive changes. It is built on 15 years of teamwork and creativity and is backed by solid research and a unique database of three billion sleep sessions. Sleep Cycle is compatible with both iOS and Android devices, making it accessible to a wide range of users.

It records snoring, coughing, breathing, sleep talking, and ambient noise
The Sleep Cycle app uses a patented algorithm for sound detection. By placing your phone near your bed, the microphone in your device will listen to your sounds, such as breathing, moving, snoring, coughing, sleep talking, and ambient noise. The app will then analyze this data and provide you with the findings. It records and monitors about 5 minutes of these sounds and marks them for your review. You can then delete any recording and/or correct the label. The app also seems to train itself to leave out certain recordings, for example, cat purring.
The app also has a feature called "Who's Snoring?" which can differentiate between snoring sounds from two or more people sharing a bedroom, enabling a more accurate picture of the user's sleep and overall health. This was made possible by applying machine learning models to distinguish between the sounds and involved a series of complex tasks, including training a model to differentiate between people's snoring using few-shot learning.
The app also allows you to compare your sleep patterns to world sleep statistics and see how different types of weather affect your sleep quality. You can also view a map of areas near where coughing is heavy.
It is important to note that the accuracy of the app's snoring detection feature has been questioned in some reviews. For example, in a review by the New York Times, a user compared Sleep Cycle's snoring detection feature to a dedicated snoring-detection app called "Do I Snore or Grind?". The former recorded no snoring, while the latter noted very heavy snoring.

The app has a Who's Snoring feature to differentiate snoring sounds
The Sleep Cycle app has a unique 'Who's Snoring' feature that can differentiate snoring sounds from two or more people in the same room. This feature is made possible by applying machine learning models to distinguish between the sounds of different people snoring. The app uses a patented algorithm for sound detection, with the microphone on the user's device listening for sounds through a highly sensitive sound detection method.
The 'Who's Snoring' feature provides a more accurate sleep analysis and clear insights into the user's snoring patterns. It records snoring, tells the user when and for how long they were snoring, and saves a few samples for the user to listen to. This feature is particularly useful for people who share a bed with a partner, as it can help identify if one person's snoring is disrupting the other's sleep.
The app also allows users to input information about their daily activities and habits, such as whether they have exercised, had a late meal, or consumed caffeine, to see how these factors correlate with their sleep patterns. This data, along with environmental markers like air pressure and phases of the moon, contributes to a comprehensive understanding of the user's sleep.
The 'Who's Snoring' feature is available to Premium subscription holders on both iOS and Android devices. It is important to note that while the app offers valuable insights into snoring patterns and their impact on sleep quality, it is not a substitute for full-night polygraphic measurements used in professional sleep clinics.
