About Sleep Monitor: Cycle Tracker
Track how you actually sleep, hear what happens at night, and wake up at a moment your body is ready for. TRACK EVERY NIGHT Start a night before bed and get a full report in the morning: how long you slept, how the night broke down into phases, and a quality score you can compare across days. Connect Apple Health and your sleep, heart rate and step data feed straight into the picture. HEAR YOUR NIGHT The microphone listens while you sleep and picks out what matters — snoring, coughing, talking, movement. Everything is analysed on your device, and you wake up to a list of clips you can play back and a waveform of the whole night. WAKE UP AT THE RIGHT MOMENT Set the time you need to be up and the alarm looks for a light-sleep moment in the half hour before it. It rings even when the app is closed or the phone is on silent, and you can fine-tune the wake-up window on the dial. FALL ASLEEP FASTER A library of rain, waves, white noise and calm music, with a sleep timer that fades out on its own. Controls stay on the Lock Screen, so you never have to open the app in the dark. REMINDERS THAT FIT YOUR SCHEDULE A bedtime reminder derived from your sleep goal, plus your own reminders for winding down, stretching or putting the phone away — each on the days you choose. SEE THE TREND Statistics by day, week, month and year: duration, quality, consistency, and how often you actually hit your goal. APPLE WATCH Start and stop a night from your wrist, and see last night's summary without reaching for the phone. SUBSCRIPTION Basic tracking is free. A premium subscription unlocks the full statistics, the complete sound library, and full access to your night recordings. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends; manage them in your Apple ID settings. Not a medical device. It does not diagnose or treat any condition, sleep apnoea included. Privacy Policy: https://sleepcycle.app/privacy Terms of Use: https://sleepcycle.app/terms
