Wake up rested. Rested Well tracks your night, shows you what actually happened while you slept, and gives you one thing to change tonight so tomorrow feels better. SEE YOUR NIGHT Put your phone on the mattress beside your pillow. Overnight, Rested Well tracks movement and sound to show when you fell asleep, when you woke up, and how long it took you to drop off. Wear an Apple Watch and you'll see your sleep stages too. Every score is broken down on screen, so you always know where a number came from. FIX YOUR SLEEP Every morning you get one specific change to try tonight, based on what happened last night. Over time, Fixing Sleep spots patterns across your nights and tells you how many nights each finding is based on. RECLAIM MISSED SLEEP Sleep debt, bedtime regularity, and weekday-versus-weekend comparisons show where your hours are going, so you can win them back. WAKE UP GENTLY The smart alarm wakes you at a light moment inside a window before your alarm time, never late. HEAR YOUR NIGHT • Hear yourself snore. Recordings stay on your phone and are deleted after a week. • Bedroom noise. See how loud your room really was and which minutes stood out. DRIFT OFF 17 sleep sounds that play offline. Mix up to three at once and set a fade-out timer. PRIVATE BY DESIGN No account, nothing to sign up for. Your sleep history lives on your phone and in Apple Health, and sound recordings never leave your device. Export everything to a file whenever you like. APPLE HEALTH Reads nights from your Apple Watch and writes back the nights Rested Well tracks. Rested Well is iPhone only.
