Sleep Smart: Smart Alarm

Wake during light sleep, not mid-dream. Sleep Smart reads heart rate and motion on your Apple Watch and rings at the best moment. Free, no account, no ads.

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
