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?

Sleep tracking and a smart alarm, using the phone you already own. No watch. No band. Nothing extra to wear or charge. Every morning: a sleep score that shows its working, and one thing to do tonight. A SMART ALARM YOU CANNOT SLEEP THROUGH Set the latest time you want to be up. For the final 30 minutes Sleepfy watches for movement and, when you are already stirring, eases you awake with sound and gentle vibration rather than a jolt. Open the app and a sunrise is waiting. The alarm is scheduled through iOS. It rings on time, at full volume, even on Silent or in a Focus mode. The gentle part is a bonus. The time is guaranteed. A SCORE THAT EXPLAINS ITSELF Trackers hand you a number. Sleepfy shows the working: sleep against your goal, how late you turned in and how steady your schedule is, each with what it cost or earned. ADVICE FROM YOUR OWN NIGHTS Not the tips every app gives you. Sleepfy reads your history and ends every insight with one thing to do tonight, and when: in bed by 10:40 PM, last coffee before 2:10 PM. Home and Trends work from the same bedtime, wake time and sleep debt. YOUR JOURNAL, MEASURED Log caffeine, alcohol, exercise, stress, screens before bed and dinner. Sleepfy lines each one up with your measured sleep, so you see how your nights compare after it. NINETY NIGHTS ON ONE SCREEN Your last 90 nights, one square each, coloured by sleep against your goal. Tap any night for its date and duration. Your score and bedtime consistency show their change from the week before. HEAR WHAT WAS IN THE ROOM Snoring, talking, coughing, a door, a dog outside. Sleepfy picks them out, times them to the minute and gives them their own card on Home. Play them back: a snoring report you can listen to is one you can check. If an alarm or a call interrupts tracking, Sleepfy picks up again as soon as iOS allows, and the minutes it missed show as a gap, never as time awake. SEE THE SHAPE OF YOUR NIGHT Deep, light, REM and awake time, with a graph of the night. They are estimates, and Sleepfy says so. Deep sleep is judged against what is typical for your age. HOW IT WORKS Before bed, tap Start and put your phone face down on the mattress near your pillow, plugged in. Sleepfy listens to the room and reads its motion sensors overnight. Short clips from the latest night are kept so you can hear them; the next night replaces them, and you can switch this off. Tap Stop in the morning and your report is ready. YOUR DATA STAYS YOURS No account to create. Your sleep data stays on your iPhone and in your private iCloud, encrypted and tied to your Apple ID. We cannot read it. Nothing is sold, there are no ads, and you can clear everything in Settings at any time. EVERYTHING ELSE • Five home screen widget styles • Streaks for a steady schedule, with a goal you can change • Change your sleep goal and manage your subscription in Settings • Private iCloud sync: your history survives a new iPhone and a reinstall WORKS WITH APPLE HEALTH Sleepfy reads from and writes to Apple Health. With an Apple Watch, it uses the Watch's measured sleep stages instead of estimates. SLEEPFY PREMIUM Sleepfy is free to download. Full access needs a subscription: • Weekly, with a 3-day free trial • Annual, with a 7-day free trial Prices vary by region and are shown before you confirm. Payment is charged to your Apple Account when you confirm. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your iPhone Settings. Any unused part of a free trial is forfeited when you subscribe. Sleepfy is a wellness app, not a medical device, and does not diagnose, treat or prevent any condition. For health concerns, talk to a doctor.
