Somnus: Sleep Debt

See your sleep over time, not just last night. Somnus: Sleep Debt reads sleep records already in Apple Health and turns them into a clear view of nightly shortfall and longer-term patterns. FROM ONE NIGHT TO TEN YEARS Explore daily, weekly, monthly, yearly, five-year and ten-year views. Longer views summarize your available recorded history; Somnus does not create missing records. SLEEP DEBT AGAINST YOUR OWN TARGET Choose a personal sleep target and see how much each tracked night falls short. Compare accumulated shortfall with your behind-or-ahead balance, where nights above target can offset nights below it. Missing nights are excluded rather than counted as a full night of debt. CONTEXT FOR YOUR PATTERNS View recorded sleep duration and stages, average sleep, target compliance, and an educational Sleep Score combining duration, efficiency, bedtime consistency, and sleep-stage proportions. Read the score's methodology and limitations in Settings. FREE AND PRIVATE No subscriptions, In-App Purchases, advertising, or accounts. Calculations happen on your device. Somnus does not upload your Health data or write to Apple Health. GETTING STARTED Requires iOS or iPadOS 17 or later and recorded sleep in Apple Health. An Apple Watch with sleep tracking enabled is the intended data source. Grant read access to Sleep Analysis to see your records. Somnus analyzes existing records; it does not independently measure sleep. Somnus provides educational wellness estimates, not clinical measurements or medical advice. It is not a medical device and does not diagnose, treat, cure, or prevent any condition. Consult a qualified healthcare professional for medical concerns.
