Sleep Cycle is an app that helps users improve their sleep by tracking their sleep patterns and providing insights. The app uses sound analysis to identify sleep states and can differentiate between two people in the same bed using microphone motion detection. When both users are connected to the same Wi-Fi, the app links their data and provides a more accurate sleep analysis. The app also offers features such as guided meditations, sleep stories, breathwork exercises, and educational portals to help users improve their sleep hygiene. While some users have found the app helpful for learning healthier sleep habits, others have noted that it may not be as accurate when used by couples, especially when tracking movements.

What You'll Learn

Sleep Cycle's microphone motion detection feature
The Sleep Cycle app has a microphone motion detection feature that tracks and analyses sleep using sound. The app picks up and filters out sounds made during sleep, including movement, snoring, coughing, and sleep talking. It also determines whether an individual is in deep or light sleep based on these sounds.
The microphone option is recommended by Sleep Cycle as it is a more powerful way of tracking sleep than the accelerometer option. The accelerometer detects movement patterns to determine whether an individual is in deep or light sleep, but it does not record sounds and requires the phone to be in the bed. With the microphone option, the phone can be placed on a nightstand or a similar surface, and the app can still track sleep in detail.
The microphone motion detection feature also allows for a more accurate sleep analysis for couples. When both phones are running the app at the same time, they can communicate with each other to determine which individual is moving. This addresses the issue of sleep monitoring apps being less accurate when more than one person is in the bed.
In addition to tracking sleep patterns, the Sleep Cycle app also provides a variety of features to aid sleep and wake-up experiences. These include relaxing music, sleep stories, meditations, gentle wake-up tones, and sleep sounds. The app also provides a detailed analysis of sleep patterns, allowing individuals to compare their sleep patterns to world sleep statistics and see how factors such as weather and daily events affect their sleep quality.

The app's ability to differentiate between two people in the same bed
Sleep Cycle is a sleep monitoring app that uses sound analysis to track and improve sleep. The app uses a patented algorithm for sound detection by listening to sounds such as breathing, snoring, and movement through the user's device microphone. It then analyzes this data and provides the user with insights into their sleep patterns and overall health.
Sleep Cycle recently launched a new feature called "Who's snoring?" which can differentiate between snoring sounds from two or more people sharing a bedroom. This feature was made possible by applying machine learning models to distinguish between the sounds of different people snoring. The app can now provide a more accurate picture of the user's sleep and overall health by identifying the individual who is snoring.
Previously, the app had limitations when it came to monitoring the sleep of couples sharing a bed. The app worked by detecting vibrations through the mattress to determine whether the user was sleeping soundly or moving around. However, it was challenging for the app to differentiate between the movements of two people in the same bed, leading to less accurate results.
With the new "Who's snoring?" feature, Sleep Cycle has addressed this issue by focusing on sound analysis rather than movement detection. By utilizing machine learning algorithms, the app can now distinguish between the snoring sounds of different individuals, even when they are sharing the same bedroom. This development allows couples to use the app simultaneously and receive accurate insights into their respective sleep patterns.

The 'who's snoring' feature for premium users
Sleep Cycle is a comprehensive sleep-tracking app that uses advanced algorithms to analyse sleep patterns and help users wake up feeling refreshed. The app works by detecting sounds and vibrations through the mattress to gauge the quality of sleep. It can also detect multiple snorers in the same room, a feature unique to Sleep Cycle among snore-tracking apps.
The 'Who's Snoring?' feature is a premium feature that allows the app to differentiate between the user and their sleep partner's snores. The feature uses a technique called few-shot learning and software similar to face-recognition tools to recognize and separate individual snores by labelling a few examples. The more the model is trained by labelling the snores it records, the better it gets at recognizing them. This feature provides clear insights into the user's snore patterns and allows them to maintain their usual sleep arrangements while receiving accurate snore analysis.
To activate the 'Who's Snoring?' feature, users need to go to the Profile tab, scroll down to Premium, select 'Who's Snoring?', and turn it on. The feature can potentially save relationships by pointing out the severity of the issue and encouraging the snorer to seek remedies or medical help.
In addition to the 'Who's Snoring?' feature, Sleep Cycle offers other premium features such as relaxing sleep sounds, sleep stories, and gentle wake-up tones and music. The app also provides detailed sleep statistics, sleep graphs, and long-term graphs to track sleep quality over time.
