The Sleep Cycle app is a toolbox for addressing a wide variety of sleep-related questions. It offers sleep tracking and a smart alarm that wakes you up when you're in a light sleep phase. The app has two motion detection modes: a microphone or an accelerometer. The microphone mode does not require the phone to be in bed with you and allows you to charge your phone overnight. However, some phone cases can interfere with the app's sonar technology, leading to inaccurate sleep data. The accelerometer mode requires the phone to be in bed and the app recommends keeping the phone on charge due to its high battery consumption.

What You'll Learn
Sleep Cycle's microphone and accelerometer modes
The Sleep Cycle app has two motion detection modes: microphone mode and accelerometer mode. The built-in microphone mode is used to analyse your movements as you sleep, and it also captures snoring and other sounds that impact your sleep quality. This mode does not require your phone to be in bed with you; instead, it can be placed on a nightstand or a similar surface. To use microphone mode, keep the Sleep Cycle app running in the foreground with your device unlocked and place your phone facing up.
The accelerometer mode also analyses your movements as you sleep. This mode requires the app to be running in the foreground with your device unlocked, and the placement of your phone will depend on your type of bed and mattress. Do not place your phone underneath your pillow or a thick mattress as it can become warm while charging. If you feel uncomfortable having your phone close to your head, you can set it to flight mode.
The microphone and accelerometer modes both track your sleep in detail, but the microphone mode is recommended as it captures more data and does not require your phone to be in bed with you. The microphone mode can be especially useful if you want to identify snoring or other sounds that may be disrupting your sleep.
Sleep Cycle also offers several other features to improve your sleep health and habits. These include a Smart Alarm, which wakes you up during a light sleep phase within a wake-up window that you set, and a Regular Alarm, which allows you to set an alarm with no phased wake-up window. You can also choose no alarm while still activating sleep analysis, and you can enable snooze functionality by double-tapping near your phone while using the microphone or on the phone for the accelerometer setting.

Phone placement and distance
The Sleep Cycle app has two motion detection modes: a microphone or an accelerometer. The built-in microphone analyzes your movements as you sleep, while the accelerometer also analyzes your movements but through data on acceleration and orientation.
For the microphone setting, you can place your phone on a bedside cabinet or on the floor next to the bed. The app will still work even if there is a bit of distance between you and the phone, but the closer the phone is to your body, the better the accuracy of the sleep analysis. If you use the accelerometer setting, you should not place your phone underneath a pillow or thick mattress as it can become warm while charging.
If you are using the microphone setting and your phone case interferes with the app's sonar technology, you may get inaccurate sleep data. Try removing your phone case the next time you use the Sleep Cycle app to see if that improves the tracking.

Phone case interference
The Sleep Cycle app has two motion detection modes: microphone and accelerometer. The app works best when the phone is placed on a bedside cabinet, though it can also be placed on the floor next to the bed. The closer the phone is to your body, the better the accuracy of the sleep analysis. The Sleep Cycle app is also dependent on a Wi-Fi signal and can use up to 30% of the phone's battery through the night. As such, it is recommended to keep the phone on charge while using the app.
Regarding phone cases, in most instances, it is fine to keep the phone case on while using the Sleep Cycle app. However, some phone cases can interfere with the app's sonar technology, which may cause inaccurate sleep data. If you experience issues with tracking, it is recommended to remove the phone case and try again.

Sleep Cycle's alarm settings
Sleep Cycle is an app that uses sound analysis to track and improve sleep quality. It has two motion detection modes: a microphone and an accelerometer. The built-in microphone analyses your movements and sleep patterns, while the accelerometer measures your sleep movements. The app should be kept running in the foreground with the device unlocked and placed correctly—ideally, the closer the phone is to your body, the better the accuracy of the sleep analysis.
Sleep Cycle's Smart Alarm Clock is one of its most popular features. The alarm wakes you up when you are in a light sleep phase, avoiding the groggy feeling you may experience when awakened during a deep sleep phase. You can set a wake-up window between 10 and 45 minutes, and Sleep Cycle will wake you up during this window when it detects that you are in a light sleep phase.
The app offers three main alarm options:
- Smart Alarm Clock and Sleep Tracking: This option combines the smart alarm with sleep tracking. You set the wake-up window that suits you, and the app wakes you up during this window when it detects you are in a light sleep phase. It also provides a full sleep analysis for the night.
- Regular Alarm: This option is for those who want to know the exact time they will wake up and don't want the wake-up window to be based on their light sleep phase. You can still access your sleep data for the night and choose from a list of soothing alarm sounds.
- No Alarm/Only Sleep Tracking: This option is for those who don't want to wake up to an alarm but still want to track their sleep. You can choose specific days for sleep analysis without an alarm, such as weekends.
Additionally, Sleep Cycle allows you to customise your alarm experience with various settings:
- Snooze: Double-tap near the phone while using the microphone, or on the phone for the accelerometer setting.
- Placement Reminders: Turn this off if you don't want reminders on how to position your phone for accurate sleep tracking.
- Auto Lock: Allows your device to lock automatically while Sleep Cycle is analysing your sleep. Disable this if you don't want to unlock your device each time you access the app after waking up.
- Battery Warning: This feature ensures you never miss an alarm due to a low battery. You can disable it by going to Profile > Settings > More > Alarm > Battery Warning > On/Off.

Other apps' interference
The Sleep Cycle app has two motion detection modes: microphone and accelerometer. The built-in microphone analyses your movements as you sleep, while the accelerometer also analyses your movements but through changes in pressure and gravity. The app works best when it is placed on a nightstand next to the bed, but it can also be placed on the floor next to the bed. The closer the phone is to your body, the better the accuracy of the sleep analysis.
Sleep Cycle does not support or recommend using other apps simultaneously as they can occupy the microphone and interfere with tracking. This may lead to inaccurate results and even cause the app to crash. For optimal performance, it is best to refrain from using other apps regardless of which motion detection mode is being used.
Additionally, some phone cases can interfere with the app's sonar technology, resulting in inaccurate sleep data. If you experience issues with tracking, it is recommended to remove your phone case during sleep sessions.
