Know your sleep debt. Know tonight's bedtime. Sleep Ledger scores last night from 0 to 100, works as a bedtime calculator, and turns the sleep you owe into a day-by-day recovery plan — all from your Apple Health sleep data. WHAT MAKES SLEEP LEDGER DIFFERENT Unlike sleep apps that drown you in data, Sleep Ledger gives you two things: a number (your sleep debt) and a plan (when to go to bed tonight). - Sleep Score, Free Every morning, last night gets a 0–100 score with the breakdown behind it: duration, bedtime consistency, and interruptions. - Bedtime Calculator Set your wake time and Sleep Ledger calculates when to go to bed tonight, based on your current debt. - Sleep Diary & Log Your nights are logged automatically from Apple Health. Add, edit, or delete any night by hand — the diary works with or without Apple Watch. - Quality-Weighted Debt Score Not just hours — Sleep Ledger uses Apple Watch sleep stage data (Deep, REM, Core) to calculate how effective your sleep really was. Six hours of deep, restorative sleep counts differently than eight hours of restless tossing. - Calendar Recovery Plan See exactly when you'll be debt-free. Sleep Ledger generates a day-by-day schedule with recommended bedtimes, adjustable for late nights and per-weekday wake times. HOW IT WORKS 1. Download and grant read access to Apple Health sleep data. 2. Sleep Ledger analyzes your past 14 days of sleep history. 3. See your current sleep debt balance instantly. 4. Follow your personalized recovery plan to reach zero debt. FEATURES Free: - Sleep debt calculation (14-day rolling window) - Recommended bedtime based on your wake time and current debt - Sleep Score: a 0–100 rating of last night (duration, bedtime, interruptions) - Sleep diary: manual sleep entry (add, edit, delete nights) - Lock Screen widgets (debt balance & recovery gauge) - Home Screen widget, Small (debt balance + days to zero) - Apple Watch complications (circular gauge, rectangular, corner) - Bedtime reminder and morning summary notifications - Siri Shortcuts (check debt, get bedtime, last night summary) - Works with or without Apple Watch - English, Japanese, German, French, Korean, and Spanish Premium: - 3-month, 6-month and 1-year trend charts - Day-by-day recovery plan with target zero-debt date - Quality-weighted debt score (sleep stages + HRV) - Sleep stage breakdown (Deep / Core / REM) - Home Screen widget, Medium (debt · last night · bedtime) - Workouts & Sleep — workout timing vs. your sleep (optional permission) - CSV data export (date, duration, stages, HR/HRV) ABOUT SLEEP DEBT Sleep debt is the gap between the sleep your body needs and the sleep you actually get. Research shows that accumulated sleep debt affects energy, mood, focus, and long-term health. The good news: you can pay it back. PRICING Sleep Ledger is free to download. Core features — today's debt balance, tonight's bedtime recommendation, Sleep Score, sleep diary, Lock Screen widgets, Apple Watch complications, and Small Home Screen widget — are always free. Premium unlocks the full recovery plan, sleep trend history, quality-weighted scoring, sleep stage breakdown, Home Screen Medium widget, and CSV data export. Annual plan includes a 2-week free trial. A 3-month plan is offered to returning users. PRIVACY No account creation. Sleep Ledger contains zero analytics SDKs, zero advertising code, and zero third-party trackers. Your sleep, heart rate, and HRV data is processed entirely on your device — it never leaves your iPhone. The only network request is triggered when you tap Settings → Contact to send feedback, and the full diagnostic payload is visible in the form before you send it. We believe your health data belongs to you and only you. Note: Sleep Ledger is a general wellness app. It is not a medical device and is not intended to diagnose, treat, or prevent any disease. Consult a healthcare professional for medical concerns.
