Most sleep apps show you a graph and leave you to figure out the rest. Sleepsyn is different. It tracks your sleep, explains what is happening, and guides you toward better nights without pressure, without guilt, and without making it feel like a chore. TRACK YOUR SLEEP Wear your Apple Watch to bed, and Sleepsyn syncs your sleep automatically. Don't have a Watch? Just log last night's sleep yourself in seconds. Tell Sleepsyn when you went to sleep, when you woke up, and rate your sleep. No complicated setup either way. The app does the rest. UNDERSTAND WHAT AFFECTS YOU Log your habits with the sleep log. Caffeine, alcohol, exercise, screen time, and stress. Over time, Sleepsyn connects the dots and lets you know how they are affecting your sleep. These are not guesses. They are your patterns, surfaced from your own data. KNOW YOUR CHRONOTYPE Take our quick 5-question quiz and discover whether you are an Early Bird, a Flexible Sleeper, or a Night Owl. Your chronotype shapes everything. Your ideal bedtime, your peak energy hours, and why fighting your natural rhythm always backfires. WIND DOWN BEFORE BED Fall asleep faster with tools designed around how your nervous system actually works. • 4-7-8 breathing — a science-backed technique that calms your nervous system in 76 seconds • Sleep sounds — rain, white noise, brown noise, ocean waves, fan, and more SEE YOUR PROGRESS Every Monday, get a beautifully designed weekly sleep card showing your average sleep, your best night, and how many times you hit your goal. On the first of every month, a full monthly report captures your bigger picture. Both are designed to be shared. Because good sleep is worth talking about. SLEEPSYN PREMIUM Want to go deeper?
