## What is Coddle Sleep Cycle?

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.

PRIVACY
No tracking. No accounts. Your diary entries live on your device.
