Sleep Smart wakes you at the right moment. A normal alarm goes off at a fixed time, whatever your body is doing — which is why some mornings feel like being dragged out of a hole. Sleep Smart watches your heart rate and how much you move overnight with your Apple Watch, and rings during a light phase of sleep inside a window before your deadline. You wake up feeling like you chose to. And if you're deep asleep the whole way through? Sleep Smart still rings at your latest wake time, every time. The smart part never costs you the guarantee. WHAT SLEEP SMART DOES • Smart wake — rings at your lightest moment inside a window you choose (up to 30 minutes) • Guaranteed backstop — always wakes you by your latest wake time, no matter what • Gentle by design — a haptic on your wrist first, then escalating audio • Haptic-only mode — wake up without waking your partner • Sleep tracking — heart rate and motion become a full hypnogram: awake, light, deep • Morning summary — time asleep, time in bed, deep sleep, awakenings, and a sleep score • Insights — see how your nights trend over time on your iPhone • Complications — next wake time and last night's score, right on your watch face • Bedtime nudge — an optional wind-down reminder so you actually hit your sleep goal • Verified iPhone alarm — see the next registered alarm and full coverage before bed • Nine-minute system snooze — with a live countdown and Stop on supported iPhones • Apple Health — your detected sleep is saved back to Health, if you allow it PRIVATE BY CONSTRUCTION Sleep Smart has no accounts, no servers, and no network code at all. Your heart rate, your motion, and your sleep history stay on your iPhone and Apple Watch. There are no ads, no analytics, no trackers, and nothing to sell — because nothing is ever collected. FREE, ALL OF IT Every feature above is free. No subscription, no unlock, no "premium" tier holding your sleep score hostage. TRY IT IN 30 SECONDS Not ready to trust it with tomorrow morning? Open Sleep Smart on your watch and tap "Test sound & taps (30 sec)" to feel exactly how the wake works, before you sleep on it. WHAT YOU NEED • iPhone with iOS 17 or later • Apple Watch with watchOS 10 or later, worn overnight • Enough watch battery to last the night Sleep Smart is a sleep and alarm app, not a medical device. It doesn't diagnose, treat, or monitor any medical condition.
