Store description excerpt
Stop waking up groggy. The problem isn't how long you sleep — it's when you wake up. Sleep happens in 90-minute cycles. Wake up mid-cycle and you feel wrecked, no matter how many hours you logged. Wake up between cycles and you feel human. CycleWake calculates the exact times that put you between cycles — for whatever alarm you already have to set. - Enter your wake time. Get 3 optimal bedtimes instantly. - Enter your bedtime. Get 3 optimal wake times instantly. - One tap sends the alarm straight to your phone's clock app. -- No account. No subscription. No internet required. HOW IT WORKS 1. Pick your mode. "I need to wake up at 6:45 AM" or "I'm going to bed at 11:30 PM." Both directions. No default schedule forced on you. 2. Enter your time. CycleWake shows your 3 best options immediately — no loading, no account creation, no permission prompts. 3. Tap a result. Your alarm is set in your phone's built-in clock app. Samsung Clock, Google Clock, any Android clock. One tap, done. Each result card shows the number of complete sleep cycles and total sleep time. The BEST card highlights the most practically achievable result, not just the longest one. THE SCIENCE Your brain cycles through light sleep, deep sleep, and REM roughly every 90 minutes. When your alarm fires mid-cycle — even after a full 8 hours — your body is dragged out of deep or REM sleep. That's the groggy, foggy, slow feeling that lasts until noon. The fix is timing, not duration. CycleWake adds 15 minutes to account for the average time it takes to fall asleep, so the math is accurate from when your head hits the pillow — not from when you set the alarm. This is the detail most sleep cycle calculators skip. WHAT'S INCLUDED - Sleep cycle calculator — bedtime mode and wake time mode - Instant bedtime calculator: enter wake time, get optimal sleep times - Wake time calculator: enter bedtime, get optimal wake times - Best time to sleep highlighted for each result - One-tap alarm integration with your phone's clock app - Works with Samsung Clock, Google Clock, and any default clock app - Material You design, dark and light theme - No account required - No internet required - No microphone, no sensors, no wearable needed FREE VS.
