What You'll Learn

Sleep Cycle works on silent with 'Do Not Disturb' mode on
Sleep Cycle is an app that helps users track their sleep and set alarms. The app uses the phone's microphone to pick up sounds that indicate the user's sleep stage. It can also be used in conjunction with the phone's 'Do Not Disturb' mode, which mutes incoming phone calls, messages, and notifications. This mode is available on both iOS and Android devices and can be customized to suit the user's preferences.
When the 'Do Not Disturb' mode is activated on iOS, the phone will not ring or vibrate for incoming calls or notifications, except from selected apps and people. On Android, the 'Do Not Disturb' mode can be customized to allow certain types of notifications or calls to come through, even when the mode is active.
It is important to note that while Sleep Cycle will still work with 'Do Not Disturb' mode activated, the app itself does not have a built-in function to mute notifications. This means that if you want to use Sleep Cycle on silent, you will need to rely on your phone's 'Do Not Disturb' mode or other similar features.
For Android users, there is an additional feature called Bedtime mode, which can be found in the Digital Wellbeing and parental controls settings. This mode can turn the phone screen gray during specified "snoozing" hours, in addition to applying the default 'Do Not Disturb' settings. Samsung smartphones have a similar feature called the Sleep feature, which can be found in the Modes and Routines app.
By using the 'Do Not Disturb' mode or its equivalent on your device, you can ensure that your Sleep Cycle app works silently without any interruptions from notifications or calls. This way, you can get a good night's sleep without any distractions while still being able to track your sleep and use the alarm features of the Sleep Cycle app.

It uses patented sound analysis technology
The Sleep Cycle app is an intelligent alarm clock that uses patented sound analysis technology to monitor and improve your sleep. With over a million users worldwide, it is the best-selling and most popular alarm clock application on the market. The app is unique in that it does not require users to place their device in bed with them for it to work. Instead, it utilizes the user's smartphone microphone to listen to sounds of bed sheets moving, with a 30 cm (10 inch) accuracy, while identifying and filtering out all sounds not generated by the sleeping user.
The Sleep Cycle app offers a range of features to help users understand and improve their sleep. It provides a full breakdown of all sleep stages, including Awake, Light, Deep, and Dream (REM), allowing users to see how noise and habits affect their rest. The app also includes a "Who's Snoring?" feature, which detects when users are snoring and wakes them up with a silent vibration, ensuring a peaceful sleep environment for both the user and their bed partner. Additionally, the app generates nightly sleep reports, tracks long-term sleep trends, and logs how daily activities impact sleep quality.
The core of the Sleep Cycle app is based on two different technology patents. The first patent enables the app to identify the optimal moment to wake a sleeping person within a predefined 30-minute alarm window, ensuring they feel rested and refreshed. This intelligent alarm clock functionality is designed to wake users during their lightest sleep phase, which is considered the best time for awakening. The second patent allows the app to track sleep using sound, providing insights into the different sleep stages and helping users understand their sleep patterns.
The Sleep Cycle app also offers flexibility in terms of privacy and consent settings. Users can choose whether they want to share their data for online backup and contribute to improving the app's analysis. Additionally, the app provides insights and advice on sleep through its journal view feature. Users can also customize their experience by selecting between microphone (sound) or accelerometer (motion) settings for sleep analysis. The app further enhances the user experience with its snooze feature, offering intelligent snooze options that gently wake users up at the end of their wake-up phase.

You can use the app with an Apple Watch
The Sleep Cycle app is compatible with the Apple Watch, allowing you to track your sleep and set alarms without needing to use your iPhone. To install the Sleep Cycle app on your Apple Watch, open the "My Watch" tab in the Watch app on your iPhone and scroll down to find Sleep Cycle in the list of available apps. Once you've installed the app, make sure you have enabled the "Show app on Apple Watch" toggle.
When you're ready to track your sleep, open the Sleep Cycle app on your Apple Watch and start a sleep session. The app will use the sensors on your Apple Watch to track your sleep. The Watch will analyze your sleep during the night and wake you up at the time you've set. It will then transfer the analysis to your iPhone, where you can view the night's sleep data whenever you like. The Sleep Cycle app also offers sleep aid features, such as sounds and stories to help you fall asleep more easily.
In addition to sleep tracking and silent wake-up, the Sleep Cycle app for Apple Watch also includes heart rate monitoring. It tracks your heart rate throughout the night and displays this data in relation to your nightly sleep graph. This allows you to see how your heart rate may impact your sleep quality. The app also provides detailed sleep statistics, long-term sleep trends, and insights into how daily activities influence your sleep.
It's important to note that the "No alarm, only sleep analysis" option is currently not available on the Apple Watch due to restrictions within the Watch OS. However, the Sleep Cycle team has expressed interest in implementing this feature if the restrictions are lifted in the future. Additionally, make sure your Apple Watch is updated to WatchOS 7.1 or later to ensure compatibility with the Sleep Cycle app.
