The service provides monitoring of a user's sleep patterns. A bedside device detects physical conditions and activities, uploading data to the service for later access by the sleeper, health care providers, or personal trainers. Data tracked include raw ballistocardiography (BCG) signals, heart rate measurements and variability (HRV), minute-by-minute actigraphy, and classification of the subject as asleep or awake at the moment of data collection.
API methods support authorization of access to a user account, followed by retrieval of information about the user and the timeline data collected by the bedside monitor. Requests can specify particular date and time ranges to gather data recorded during those spans. In addition to BCG and HRV, returned data report on conditions in the room such as light and sound levels.
