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.
Timer

An interval timer for routines you build yourself: any number of steps, in any order, repeated as often as you like, with your own voice and your own pictures. Free. No advertising, no purchases, no subscription. A COUNTDOWN YOU CAN READ ACROSS THE ROOM One number, as large as the screen allows. The exercise plays in a band above it while you copy the movement, and a bar along the bottom shows every round, step and rest at once — so you always know how much is left. YOUR OWN VOICE Record a note for any step and hear it the moment that step arrives. Where you have not recorded one, the phone reads out the step's name as it begins, so you are never guessing what to do next. IT WORKS WITH THE SCREEN OFF The cues sound with the phone locked and in your pocket, and they sound through the silent switch. A timer that goes quiet when you need it is not a timer. TWO ROUTINES TO START WITH A back stretch and an active workout, filmed and ready to run. Change them, or build your own from nothing: your steps, your durations, your rests, and a video or a photograph behind each one. SIX COLOUR THEMES The original gold, plus Aquatic, Nature, Candy, Energy and Lagoon. Chosen in the settings, applied everywhere the app draws — the running screen included. Every one is measured for contrast, so the countdown reads the same in pink as it does in gold. NOTHING LEAVES THE PHONE No account, no sign-in, no analytics. The app holds no network permission at all, so it could not send anything anywhere even if it were asked to. Your recordings and your pictures stay in the app's own storage and are deleted with it. MADE TO BE USED MID-SET Large type, high contrast, full VoiceOver support with each phase announced as it changes, and haptics for when the ear misses a cue. Twenty-seven languages.

Verdict
Sleep Smart and Timer are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
