About Moondawn: Sleep Cycle Alarm
Wake up between sleep cycles, not in the middle of one. Sleep moves in roughly 90-minute cycles: light sleep, deep sleep, REM, then a moment where you're almost awake. An alarm that fires during deep sleep leaves you groggy for hours. An alarm that lands between cycles lets you start the day clear-headed. It's why 7 and a half hours can feel better than 8. Moondawn does one thing well: it aims your alarm at that moment. GOING TO BED NOW Tell Moondawn you're turning in and it lays out your wake-up options, one for every full cycle, from a quick power nap to a full night. Tap one and the alarm is set. WAKE AT A SET TIME Have to be up by 7:00? Spin the wheel and Moondawn counts backward, showing exactly when to fall asleep so the alarm still lands on a cycle boundary, down to the minute. WIND-DOWN REMINDERS Pick the bedtime you're aiming for and Moondawn nudges you before lights-out, so you actually get the night you planned. REAL ALARMS THAT RING Built on Apple's AlarmKit, Moondawn rings full-screen through Silent mode and Focus, even if the app is closed. No "leave the app open overnight" tricks. No missed mornings. SOUNDS YOU'LL WAKE TO, NOT DREAD Eleven original wake tones, each written to rise gently instead of jolt you awake, plus a silent vibrate-only option. Hear any of them before you choose. MADE FOR THE DARK A calm night sky, glass surfaces, a slowly breathing moon, and a light tap of haptics as everything responds. No streaks, no guilt, no feed. Open it, tap once, sleep. Clocks follow your 12- or 24-hour setting automatically. MOONDAWN+ One purchase, yours forever. No subscription. Unlocks unlimited simultaneous alarms, four night skies with matching app icons, and tuning for your own cycle length and time to fall asleep. PRIVATE BY DESIGN Moondawn collects nothing. No accounts, no tracking, no analytics. Nothing ever leaves your phone. Sleep is timing. Moondawn gets it right.

Sleep is timing. Thanks for waking up with us.
