Sleep Diary - MyDailySleep

A simple sleep diary for better nights. Log bedtime, wake time, sleep quality and morning mood in a few seconds, and see what your good and bad mornings have in common.

No wearable, no account, no complicated setup. Drag the moon and the sun on the sleep dial, tap the stars, pick your mood — done.

◆ A real sleep diary
Doctors and sleep clinics often ask for a sleep diary. MyDailySleep keeps the details they ask about:
- Time to fall asleep and night wakings
- Naps, caffeine after 4 pm, alcohol and exercise
- A note for dreams you remember
Export the last 14 days as a one-page PDF table and share it before your appointment. (MyDailySleep is a sleep log, not a medical device, and does not diagnose.)

◆ Sleep log in seconds
- Sleep dial: set bedtime and wake time by dragging
- One-tap buttons: "Sleep now", "Usual" and "Wake now"
- 1–5 star sleep quality and morning mood
- A sleep score from A to F with a breakdown

◆ See your patterns
- Calendar and list history with monthly summaries
- 7, 30 and 90-day trends for sleep duration, quality, mood and score
