Are you running on a sleep deficit? Sleep Ledger reads your Apple Health sleep data to calculate how much sleep you owe your body — and builds a personalized, day-by-day recovery plan to help you pay it back. 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). - 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. - Lock Screen, Home Screen & Apple Watch Complications Your debt balance and tonight's bedtime — always one glance away on your lock screen, home screen, or watch face, without opening the app. - Private by Design, On-Device Processing No account creation. No analytics SDKs. No advertising code. No third-party trackers. Your sleep, heart rate, and HRV data is processed entirely on your device. The only network request happens when you send us feedback from Settings → Contact, and the diagnostic details are shown before you send them. HOW IT WORKS 1.
