About

SnoozeSync

Features
Read full description

SnoozeSync is a clinically-grounded sleep improvement program built on Cognitive Behavioral Therapy for Insomnia (CBT-I) — the gold-standard, non-medication treatment recommended by sleep doctors worldwide. Unlike sleep trackers that just measure your sleep, SnoozeSync actively retrains your brain to sleep better. In as little as a few weeks, most users experience lasting improvement in sleep quality, falling asleep faster, and waking up feeling truly rested. HOW IT WORKS SnoozeSync guides you through the four proven pillars of CBT-I: • Sleep Diary — Log your sleep every morning to track your Sleep Efficiency score. Your data drives your personalized prescription. • Lessons — Science-based modules that identify and fix the habits, thoughts, and behaviors keeping you awake. Learn why you can't sleep and how to fix it for good. • AI Coach — Your personal sleep expert, available 24/7. Ask anything about your sleep, your progress, or CBT-I techniques and get expert, evidence-based guidance. • Relaxation — Tactical breathing and wind-down exercises designed to lower bedtime arousal and quiet a racing mind. YOUR CBT-I PRESCRIPTION Every night, SnoozeSync gives you a personalized sleep window — a specific bedtime and wake time calculated from your diary data. By anchoring to a consistent wake time every single day (including weekends), your circadian rhythm resets and your sleep drive rebuilds naturally. WHO IT'S FOR SnoozeSync is designed for anyone who: • Lies awake for hours trying to fall asleep • Wakes up at 3 AM and can't get back to sleep • Wakes too early and feels unrefreshed • Has tried sleep aids, supplements, or trackers without lasting results WHAT MAKES SNOOZESYNC DIFFERENT CBT-I is proven more effective than sleep medication for chronic insomnia — and unlike pills, the results last. SnoozeSync puts this clinically-validated program in your pocket, with a personalized approach that adapts as your sleep improves.
