Every night as a strip, scored against your own need rather than a flat eight hours.
Full Strides sets a personal sleep need from the median of your recent nights, held between seven and nine hours. Duration is scored against that need. Someone who sleeps seven hours and feels fine is not marked short every single night.
Duration, 75%. Three hours under your need scores 0. One hour under scores about 72. Meeting it scores 100, with an hour of grace before the score tapers again.
Efficiency, 25%. Time asleep divided by time in bed, when the watch tracked stages. 70% scores 0, 85% scores 75, 95% and above scores 100. Without stage data, efficiency drops out and duration carries the score.
80 and up, Ample.
60 to 79, Rested. No color in the app.
40 to 59, Modest.
20 to 39, Short.
Under 20, Deprived.
The Sleep screen draws each night the way Apple Health does: one strip per night on a clock from 6 PM to noon, bedtime at the top, stages down to wake. Deep, core, REM, and awake use Health's own colors, so a Full Strides night reads like the Health one. Choose fourteen, thirty, or ninety nights, and tap any night for its detail.
Below the strips: your bedtime and wake time with their spread across the period, the month's stage mix, and a seven-night balance that shows how far above or below your need the week ran.
Apple Health sometimes records a ten-minute sleep when the watch detects stillness after waking. Full Strides treats anything under three hours as no night recorded rather than scoring it as deprivation.
Sleep between noon and 6 PM is left out of the night. A night is keyed to the morning it ends on.
Sleep in Full Strides is a wellness summary, not a medical assessment. Sleep needs vary by person, and yours is estimated from your own recent nights.
