Sleep Ledger: Sleep Diary
10-sec check-in, no scores
Free · In‑App Purchases
Open your sleep diary from widgets, Control Center, Siri, or Shortcuts. Add optional Apple Health HRV context while keeping your own ratings first.
"I tried sleep apps, but the scores just made me more anxious."
SleepLedger is a calm sleep diary for people who want to remember how sleep actually felt, without another score overriding their body.
Log last night in about 10 seconds, see weekly patterns, and export a clear 2-week diary when a doctor, therapist, CBT-I session, or personal review needs context.
WHAT YOU CAN DO
1. LOG THE MORNING AFTER
Capture the part wearables can miss:
- Sleep quality
- How rested you felt
- Energy today
- Optional context like sleep latency, awakenings, stress, caffeine, exercise, travel, and notes
2. SEE PATTERNS WITHOUT SCORE PRESSURE
Your 7-day view helps you notice whether sleep is changing over time, without an algorithm judging your night.
3. ADD STRUCTURE WHEN YOU WANT IT
Use the optional weekly ISI (Insomnia Severity Index) check-in when you want a more structured reflection. It is informational self-tracking, not a diagnosis.
4. GET TO YOUR CHECK-IN FASTER
Open today’s entry from Home Screen and Lock Screen widgets or the Control Center button. Use Siri or Shortcuts to open your check-in or save sleep quality and restedness. Try “Record sleep in Sleep Ledger.” Existing entries open for review instead of being overwritten.
5. EXPORT A 2-WEEK SLEEP DIARY
Create PDF or CSV exports for personal reflection or care conversations. A recent 14-day range is built in so you do not have to assemble a two-week diary manually.
6. CHECK IN ON APPLE WATCH
Record sleep quality and how rested you feel from your wrist. Your check-in syncs with your paired iPhone. If the phone is unavailable, the watch keeps the saved check-in pending until syncing can resume.
7. ADD APPLE HEALTH CONTEXT
With your permission, read sleep timing, estimated duration, and time in bed from Apple Health. Compare available sleep-duration trends with your own ratings, and include that context in PDF/CSV exports. This is optional: your diary works without Apple Health. SleepLedger does not automatically measure sleep or write your ratings to Apple Health.
Optionally connect HRV separately to view available SDNN readings for a sleep window. HRV is context, not a stress measurement or recovery score, and is not included in your journal or exports.
