Cotton: Sleep Tracker & Sounds

Sleep tracking with your watch, your band or just your iPhone. Sleep sounds to drift off. And small habit experiments that show what changes your sleep. TRACK WITH A BAND OR JUST YOUR IPHONE Wear an Apple Watch or another band that writes sleep to Apple Health, and Cotton reads your time asleep, sleep stages, heart rate and HRV. No wearable? Place your iPhone by your pillow and Cotton estimates sleep and wake, still and restless time from motion and sound, analysed on your iPhone. On the nightstand it listens for snoring only. HEAR YOUR NIGHT See when you snored, talked or coughed during the night, and play back short clips of breathing, snoring and noise. Clips are optional, stay on your iPhone and are deleted after 30 days. A SLEEP SCORE YOU CAN READ Cotton's sleep score summarizes hours versus need, sleep consistency, efficiency and sleep stress when enough records are available. Tap it to see every part. It is a wellness estimate, separate from Apple's Sleep Score. Sleep stages, heart rate and HRV come from a wearable; phone tracking does not measure them. SLEEP SOUNDS Mix rain, ocean, nature, white and brown noise, fans and ASMR, or play a meditation or a bedtime story. Set a timer that fades out. Audio keeps playing while your iPhone is locked. TEST WHAT HELPS Answer a short journal each morning about habits like late caffeine, screens or alcohol. Cotton shows how your score looks with and without each one, and short experiments end in a clear keep or drop. These comparisons help you explore patterns; they do not establish cause and effect.
