About 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 OPEN AND USE IT — HONESTLY No forced trial to open the app. No credit card wall. The bedtime calculator and sleep log are free, forever. LullCycle Plus is an optional subscription — clearly priced, cancel anytime. LullCycle Plus (optional subscription) • Auto-renewing monthly or yearly subscription • Payment charged to your Apple ID at confirmation of purchase • Renews automatically unless canceled at least 24h before the period ends • Manage or cancel anytime in your App Store account settings MEDICAL DISCLAIMER LullCycle is not a medical device and does not provide medical advice, diagnosis or treatment. Sleep information and scores are for general wellness purposes only. Always consult your doctor about sleep disorders or before making any health decisions.
