Enter bed/wake times, sleep onset, night wakings, and habits to estimate sleep efficiency, a composite quality score, and rough sleep debt - wellness planning only.
Quick answer: Sleep Quality Score Calculator
Efficiency-ish math from bed window minus latency/wakes plus habit penalties for caffeine/screens.
Example: 7h in bed, 30m to sleep, two wakes → lower efficiency than an uninterrupted 7h night.
