What You'll Learn
The app tracks your sleep patterns and sleep stages
The Sleep Cycle app works by tracking your movements during the night. It relies on your smartphone's accelerometer to monitor movement and detect when you fall asleep. The idea is that you place your smartphone near you in bed, and it will register your movements. The app will document periods of stillness, which indicate that you are in a deeper sleep, especially REM sleep. It will also seize on periods of wakefulness towards the morning, when you are drifting into lighter stages of sleep, to alert you to get up for the day.
Sleep Cycle also captures your nighttime sounds – including snoring, sleep talking, or other surprising noises. The app uses a patented algorithm for sound detection, listening and analyzing your breathing, movements, and snoring through a highly sensitive sound detection method. It then correlates this data with your habits and external factors, including your surroundings, to give you a comprehensive picture of your overall sleep health.
The app also allows you to add sleep notes with details on whether you exercised, had a late meal, or drank coffee before bed. This enables you to see how different activities affect your sleep quality and gain insights into your sleep patterns over time. The Sleep Goal feature allows you to see the benefits of a consistent sleep schedule for your sleep quality. The app also takes into account various environmental markers, such as air pressure and the phases of the moon, which can influence your sleep.
Sleep Cycle aims to help you understand the effects of sleep duration, sleep stages, consistency, and interruptions on your overall well-being. With this information, you can make adjustments to improve your sleep quality and consistency.

Sleep Cycle recently announced the launch of the 'Who’s snoring?' feature. This 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 development 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 captures every breath, unveiling the precise rhythm of your nights. It helps you understand the effects of sleep duration, sleep stages, consistency, and interruptions. With nightly reports at your fingertips, you can make informed adjustments for better, more consistent sleep.

It provides a Sleep Quality score
The Sleep Cycle app provides a Sleep Quality score, allowing users to determine if there are certain factors that could be disrupting or improving their sleep. The app gathers data on the user's actions and surroundings to allow them to see correlations between their activities and sleep over a length of time. Users can add sleep notes with details on whether they exercised, had a late meal, or drank coffee after 5 pm before each sleep session. This will give more meaningful insights over time and help users understand whether certain habits are affecting their sleep. Other measurements include regularity through the Sleep Goal feature, where users can see the benefits of a consistent sleep schedule for their sleep quality.

However, these apps can still help users become more attuned to their circadian rhythms and understand the importance of sleep in their overall health.
