SEE EVERY STAGE OF YOUR NIGHT • Awake, REM, light and deep sleep, shown on a stage ring and a full-night sleep pattern chart • Bedtime, wake-up time and total sleep for every session • History with day, week, month and year views to spot trends AN AI SLEEP COACH THAT STAYS ON YOUR PHONE Ask about your sleep, your routine or why you wake up tired.
