Track your sleep with the iPhone already on your nightstand. No watch, no band, no extra hardware. Rested turns your phone into a gentle sleep lab: it senses your movement and (if you allow it) listens for snoring and sleep talk, then greets you each morning with an honest Sleep Score and a clear picture of your night. YOUR FIRST NIGHT IS FREE Set your phone on the mattress, tap Start, and sleep. In the morning you'll see your full report: Sleep Score, sleep timeline, disturbances, and one insight about your night. Decide afterwards whether Rested is worth keeping. We think you'll stay. WHAT RESTED DOES • Your own AI Sleep Coach. Ask why last night went the way it did, how to fall asleep faster, or what to change tonight. It reads the nights Rested has tracked for you, follows the thread of your conversation, and answers with practical, evidence based guidance. • Sleep tracking with no wearable required. Motion and sound analysis from your iPhone estimate when you fell asleep, how continuous your sleep was, and when you were restless. • Smart Alarm. Set a wake window (say, 6:45 to 7:15) and Rested wakes you at your lightest moment inside it, never later than the end of the window. Mornings feel easier when the alarm works with your sleep instead of against it. • Snore and sleep talk detection, so you hear what you can't remember. Short clips of detected snoring, coughing, or talking are saved on your phone for playback in the morning. Audio is analyzed entirely on your device and never uploaded. • A Sleep Score you can trust. A 0 to 100 score built from your sleep duration, continuity, schedule consistency, and disturbances. When we have less data (no mic access, for example), we say so and score with what we have, with no invented precision. • Tag what affected your night: caffeine, alcohol, stress, late screens and more. Rested links your tags to your Sleep Score over time and shows which ones actually matter for you. • Streaks and consistency, because the habit is what changes your sleep. Rested tracks your streak and a weekly consistency score. Missed a night? Log it manually so your progress isn't punished. • Sleep sounds and mixer. A curated library of noise, rain, ocean, and ambient loops. Layer up to three, set a sleep timer, and save as many named mixes as you like. • Works with Apple Health. If you wear an Apple Watch to bed, Rested automatically uses its data for a sharper analysis, and writes your sessions back to Apple Health. No Watch? Everything still works. • Trends that keep you honest. 7 and 30 day views of your score and duration, plus your full night by night history. PRIVATE BY DESIGN Your sleep data is stored on your iPhone. No account required, no analytics SDKs, no ads, and your data is never sold. Audio is analyzed on your device and never uploaded. When you ask the Sleep Coach a question, your question and a summary of your sleep stats are sent securely to write the answer; recordings never are. Export or erase everything, any time, from Settings. RESTED PRO Your first tracked night and its full morning report are free, and so is the Sleep Coach, including a few answers from its full version. Continue with Rested Pro for every night and unlimited answers from the full Sleep Coach: $2.00/week, $6.00/month, or $39.99/year with a 7 day free trial (cancel anytime, at least 24 hours before the trial ends, and you won't be charged). A one time Lifetime unlock is also available. Subscriptions renew automatically unless cancelled in your Apple Account settings. A NOTE ON HONESTY Rested estimates sleep for general wellness. It is not a medical device and does not diagnose or treat any condition. The Sleep Coach is an AI, not a doctor. If you're worried about your sleep, please talk to a doctor.
