Night Ledger is a personal sleep diary for iPhone, built hand in hand with a sleep medicine clinician to help people understand their sleep patterns to sleep better. Log last night’s sleep in the morning, keep a personal history, and export a report when you want to share it with your clinician, therapist, or care team. Everything stays on your device. There is no account, no iCloud sync, no analytics, and nothing is uploaded. You can save a complete morning log, keep a draft, skip a day, or edit later. Trends cover 14, 28, and 90 days. Exports include PDF, CSV, and JSON. Reminders are local. Night Ledger was designed with real clinical sleep diary workflows in mind, including insomnia care, CBT-I support, and sleep efficiency tracking. Night Ledger does not diagnose, treat, prescribe, or recommend. It does not give medication guidance. It is a private tracking tool to help you organize your sleep information and review it with a qualified clinician when appropriate.
