Wake up inside your dreams. DreamKnock turns your Apple Watch into a lucid-dreaming trainer. While you sleep, the DreamSense™ engine reads your heart-rate dynamics and wrist stillness to sense when you're dreaming — then plays a gentle, distinctive haptic rhythm, soft enough not to wake you. Trained by day, that rhythm means exactly one thing inside a dream: this is a dream. HOW IT WORKS • Tap Start Sleep, set your intention, and drift off • DreamSense™ fuses heart-rate dynamics, micro-motion atonia sensing and sleep-architecture modeling — self-calibrating to your body every single night • When REM holds, a quiet cue slips into your dream BUILT TO PROTECT YOUR SLEEP • Adaptive backoff: if a cue wakes you, the next one waits twice as long; three awakenings stop cues for the night • Cues wait for the REM-rich second half of the night • A battery guard ends the session gracefully and saves your report THE COMPLETE METHOD • Wake Back to Bed (WBTB) timed gentle wake • MILD intention screen at bedtime • Daytime rhythm training and reality-check reminders • Morning report: REM timeline, cue moments, heart-rate curve, sleep latency • Dream journal with dictation, lucid wins and dream-sign tags • Trends: lucid rate, REM per night, your top dream signs • Three cue rhythms, three strengths PRIVATE BY DESIGN No account. No cloud. No analytics. Heart-rate data is processed on your watch via HealthKit and never leaves the device. Your Apple Watch runs the whole night on its own — your iPhone can charge in another room. Requires iPhone (iOS 17) and Apple Watch (watchOS 10) or later. DreamKnock is a wellness tool, not a medical device. Sleep inferences are estimates and vary by person. What's New: Welcome to DreamKnock 1.0 — sweet dreams, and see you on the other side of the mirror. Privacy Policy: https://dreamknock.com/privacy Terms of Use (EULA): https://dreamknock.com/terms
RemWake
Read full descriptionHide full description
Most mornings you stir a few times before your alarm goes off. A normal alarm doesn't care. It rings on the minute, and if it catches you at the wrong point you feel it all day. RemWake gets a window instead. You set the time you have to be up and how early it's allowed to wake you, and it spends that window waiting for one of those moments. Catch one and getting up is easy. Some nights there isn't one, and then it just rings at your set time. You won't oversleep. WITH AN APPLE WATCH Your watch sleeps until the window opens, then wakes up and reads wrist movement and heart rate for up to half an hour before your set time. It wakes you with a buzz rather than a noise, so nobody else in the room hears it. Nothing runs the rest of the night, so it barely touches your battery. WITH YOUR IPHONE Put it on the mattress and it reads movement all night, however long your window is. OR RUN BOTH This is the good one. Your iPhone watches the whole window and your Watch takes over for the last half hour, so you get a long window and still get woken by a buzz on your wrist instead of a noise. They talk to each other, so you only get woken once. IT LEARNS FROM YOUR OWN SLEEP If you've worn a watch to bed, RemWake reads your sleep history out of Apple Health and works out how often you actually stir before your alarm. It'll tell you straight what a given window is worth for you. Some nights you don't stir at all, and on those it just wakes you at your set time. SLEEP SOUNDS Rain, ocean, white noise, brown noise, with volume control. One plays for as long as your iPhone is tracking — that's what keeps it awake to sense the night. Tracking on Apple Watch instead is completely silent. WHAT YOU GET IN THE MORNING Your heart rate across the whole night, how restful it was, how long you were in bed, and the exact moment RemWake picked to wake you. There's no account and nothing to sign up for. Your sleep data stays on your phone. You can share anonymous data to help improve the wake detection if you want to, but it's off until you turn it on. FREE AND PREMIUM Free gets you the smart alarm on either device, last night in full detail, and the rain sound. Premium adds your whole history, Trends, the other three sounds, 60 and 90 minute windows, and CSV export. $7.99 a month with a week free. $69.99 a year with a month free. Or pay $249.99 once and it's yours. RemWake isn't a medical device and won't diagnose anything. SUBSCRIPTION TERMS Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically at the same price unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings.
