Coddle Sleep Cycle

Plan bedtimes and wake times that line up with your 90-minute sleep cycles. Wake up between cycles, not in the middle of one. Calm, focused, no fluff.

Coddle is a calm sleep planner built around the 90-minute sleep cycle, so you wake up between cycles instead of in the middle of one — refreshed, not groggy.

Pick a wake time and Coddle shows the bedtimes that land on a clean cycle. Going to bed now? Tap once and Coddle picks the smartest wake times. That is the entire flow — no scrolling, no upsells, no popups.

KEY FEATURES • Sleep cycle calculator for bedtime from a wake target • Wake-up calculator for sleeping now or at a chosen bedtime • 4, 5 and 6 complete cycles with their total sleep duration • Adjustable fall-asleep buffer (default 15 minutes) • Sleep diary to log bedtime, wake time and how you felt • Stats view to see weekly sleep duration and quality trends • Soothing indigo night theme, easy on tired eyes

DESIGNED FOR HUMANS WHO ACTUALLY SLEEP Coddle is a small, focused tool, not a sleep tracker that wants your microphone or your heart rate. There is no account, no sync, no advertising. Open it, plan, sleep.
