• Breathing disturbances (Respiratory Scan): detection of breathing disturbances via the PPG sensor (sleep heart rate, oxygen saturation levels and heart events).
• Sleep: duration, deep and light phases, sleep interruptions
• Elevation: number of floors climbed
• Walking and running: steps, distance, calories
