Know more about your nights, one record at a time. Sleep Diary makes it simple to log when you went to bed, when you woke up, and how rested you felt. Keep night sleep, naps, and split sleep together, even when your schedule changes. SEE MORE THAN HOURS IN BED Add sleep-onset or awake time to your night records to see estimated sleep efficiency. Basic records, naps, and short sleep are not included in this average. Review average sleep duration, night awakenings, and your own sleep-quality and morning-energy ratings. Estimates come from your entries; the app does not automatically measure sleep or sleep stages. TRACK WHAT MATTERS TO YOU Record caffeine, exercise, stress, or other parts of your day alongside your sleep. Add your own factors, rename custom factors, and hide or restore items. Your past records stay connected. Factor statistics show how often you recorded each item, without claiming cause and effect.
