How to use it
- Enter the date, bedtime and wake-up time for a night.
- Add how long it took to fall asleep and how often you woke.
- Rate the night and add any notes (caffeine, stress, exercise…).
- Review your weekly or monthly trends and export a CSV anytime.
Understanding your results
Estimated sleep = time in bed minus time to fall asleep. All values are self-reported estimates, not medical measurements.
Why keep a sleep diary?
A few weeks of notes can reveal links between your habits and how you sleep. A diary is also useful to bring to a healthcare professional if you're discussing sleep concerns.
