LullCycle: Sleep Cycle Alarm

LullCycle tells you the smartest time to go to bed tonight — computed from real sleep science, not vague advice.

Sleep moves in roughly 90-minute cycles. Wake up mid-cycle and you feel groggy; wake at a cycle boundary and the same amount of sleep feels lighter. LullCycle does the math for you: set your wake-up time and instantly see the bedtimes that land your alarm between cycles.

WHY SLEEPERS CHOOSE LULLCYCLE • One-tap bedtime calculator, timed to ~90-minute cycles + realistic fall-asleep time • Night score for every night — duration, cycle alignment and timing, transparently computed • 7-day sleep debt that shows exactly how far behind you are • Consistency streaks that reward a steady schedule • 100% on-device and offline — your sleep data never leaves your phone
