Healthy Sleep Cycles

Better mornings start with a realistic plan for tonight. Healthy Sleep Cycles helps you choose when to sleep or wake, protect enough rest, set a practical alarm, and build a calmer nightly routine. No account or subscription is required. PLAN TONIGHT Choose “Sleep now” or “Wake at,” then adjust your normal time to fall asleep. Recommendations prioritize at least seven hours of sleep before using a flexible 80–100 minute cycle estimate to suggest practical options. The clearest choices are marked Best. SET A WAKE ALARM Select a recommendation, choose a label and snooze time, then set the alarm. On iOS 26 or later, Apple’s AlarmKit provides system alarm presentation with Stop and Snooze controls. Earlier iOS versions use a notification fallback and clearly explain its limits. MAKE OURA USEFUL Optionally connect Oura to summarize up to 30 recent nights. See typical sleep duration, latency, efficiency, bedtime consistency, wake consistency, and recent trends. Your typical duration and latency create a more personal bedtime suggestion. Every core feature works without Oura. UNWIND WITH 16 SOUNDS Play rain, ocean, fireplace, forest, white noise, pink noise, brown noise, and more. Set a 5–120 minute sleep timer or download the full sound library for offline playback. BUILD A GENTLE ROUTINE Your chosen alarm saves tonight’s plan. The wind-down reminder starts enabled and saves changes automatically. Record how rested you feel each morning, follow your check-in streak, and see your recent seven-day score. PRIVACY BY DESIGN Plans, settings, check-ins, downloaded sounds, and cached Oura summaries stay on your device. Oura credentials use the iOS Keychain. There is no advertising, analytics SDK, or cross-app tracking. Sleep cycles vary from person to person. Healthy Sleep Cycles is a general wellness planning aid, not a medical device, diagnosis, or sleep-stage detector.
