How to Use This Calculator
- Enter your total time in bed (hours) and how long it took to fall asleep (minutes).
- Record the number of night awakenings and average duration of each awakening (minutes).
- Select your wearable's sensor type (accelerometer-only, accel+PPG, accel+PPG+SpO2, or EEG headband).
- Enter your age and hours before bed that you last consumed caffeine.
- Review sleep quality score, sleep efficiency (%), estimated deep sleep and REM sleep minutes.
