Sleep as Android uses a method called actigraphy to track sleep patterns
Sleep as Android is a mobile app that helps users track their sleep patterns and make recommendations to improve their sleeping habits. The app uses a method called actigraphy to track sleep patterns. Actigraphy is a type of wearable sleep test that uses sensors to track body movement and detect sleep phases. It defines two sleep phases: light sleep and deep sleep. During deep sleep, muscular movements are suppressed, resulting in a flat sleep graph.
Sleep as Android utilizes the phone's built-in accelerometer sensor, which is highly sensitive to movement. The phone is placed on the mattress near the user's body, allowing it to sense and record their movements throughout the night. This data is then used to determine the user's sleep phases and provide insights into their sleep patterns.
Actigraphy, as used by Sleep as Android, offers a convenient and reasonably accurate method for tracking sleep. While it may not provide the same level of detail as polysomnography (PSG), it is more accessible and does not require expensive equipment. The app's algorithms have been compared to sleep lab results, showing strong correspondence between light and deep sleep phases measured by the app and those observed in clinical settings.
It is important to note that Sleep as Android also offers additional tracking options, such as using the phone's microphone and speaker as a sonar for range and movement detection. This feature may not work on all phones, as it requires the ability to produce and capture frequencies above the human hearing range. Additionally, the app allows for the adjustment of sensitivity settings and the disabling of awake detection to fine-tune sleep duration calculations.

It can track sleep with the phone's microphone and speaker as a sonar
Sleep as Android is a mobile app that can track sleep patterns and make recommendations to improve sleeping habits. It uses the phone's microphone and speaker as a sonar to detect range and movement using ultrasound. The app works on many phones, but not all, as some cannot produce or capture frequencies above the range of human hearing.
The Sleep as Android app uses ultrasound to detect movement and range, which is generally considered safe if it is at a normal volume. The volume of ultrasound used by the app is around 40 dB, which is lower than normal speech volume and is not loud enough to damage your hearing.
To use Sleep as Android with sonar, the phone should be placed within one meter of your body. The app will then use the phone's speaker and microphone to detect movement and range using ultrasound. The app will also use the phone's accelerometer to detect movement, which is sensitive enough to detect small movements, such as when the phone is left on a table.
Sleep as Android offers a range of other features to help track and improve sleep. For example, the Smart Wake-up feature finds the best time to wake up based on your sleep cycle. The app also allows you to set up an alarm and adjust the sensitivity of the settings to get optimal results.
