Description
Wake up feeling refreshed every morning with WakeCycle - the scientific alarm clock that works with your natural sleep cycles.
Say goodbye to morning grogginess and sleep inertia. WakeCycle uses scientifically proven 90-minute sleep cycle calculations to time your wake-up perfectly during REM sleep (light sleep), so you start your day alert and energized.
KEY FEATURES:
2-Stage Alarm System
Our unique 2-stage alarm gently prepares your brain before waking. Stage 1 plays a soft, gentle sound 20 minutes before your target wake time, allowing your body to transition naturally from deep sleep. Stage 2 sounds at your set time to ensure you wake up on schedule. This gradual approach dramatically reduces the stress of sudden awakening.
90-Minute Sleep Cycle Optimization
Human sleep follows approximately 90-minute cycles, alternating between deep sleep and REM (light) sleep. Waking up during deep sleep causes grogginess, while waking during REM leaves you feeling refreshed. Simply set your wake time, and WakeCycle calculates the optimal bedtime to complete full sleep cycles.
Smart Bedtime Notifications
Receive personalized bedtime reminders based on your wake time. Build healthy sleep habits by going to bed at the optimal time for your schedule.
Intuitive Sleep Visualization
See your sleep patterns at a glance with our beautiful wave graph. Understand how sleep cycles work and why timing matters for quality rest.
Beautiful Midnight Glow Theme
Eye-friendly dark mode design perfect for use in dark bedrooms. Elegant interface with smooth animations makes setting alarms simple and pleasant.
Scientific Evidence Based
WakeCycle is designed based on research from the National Heart, Lung, and Blood Institute (NHLBI) and the Sleep Foundation. We follow the latest sleep science to recommend optimal sleep duration and wake timing.
HOW IT WORKS:
Step 1: Set your desired wake time
Step 2: Receive a bedtime notification at the calculated optimal time
Step 3: Go to bed and fall asleep naturally
Step 4: Wake up refreshed as our 2-stage alarm guides you through the sleep cycle

Build 883828073v1.22026-03-27 11:13:45
Added support for native iOS alarms (iOS 26 and later)
On iOS 26 and later, the app now uses Apple’s AlarmKit framework, so alarms appear in the iOS Clock app. They will sound reliably even if the app is closed, and snooze works natively through the OS. Custom alarm sounds (“Gentle Sound” / “Energetic Sound”) also play even in Silent Mode.
Added a “Sleep Now” button
This button appears when the alarm is turned on and automatically calculates and sets the optimal wake-up time based on the current time. It uses four sleep cycles (about 6 hours) as the baseline and instantly rounds the result to either :00 or :30.
Improved alarm volume testing
The “Check Volume” button now plays immediately at the alarm’s actual maximum volume (100%). Since normal alarms start at 20% and gradually increase, this makes it possible to confirm the true maximum volume during testing.
Improved alarm management reliability
We introduced fixed-ID alarm management, enabling immediate rescheduling when the alarm time changes, automatic cleanup of unnecessary alarms when the app launches, and prevention of duplicate alarms.
Improved the home screen and launch screen
We removed the bedtime toggle switch and now always display the recommended bedtime. The launch screen has also been updated to a design with a black background and the app icon, creating a smoother startup experience that matches the app’s dark theme.
