Tap the sleep figure on Today.

The score at the top

One number for last night. Which score you see depends on your source and your settings — it may be your device’s own (Oura’s or Polar’s), or the Workbench’s own calculation. The app labels which. That matters: two published methods can look at one night and disagree by ten points, and neither is wrong.

The hypnogram

The coloured chart of your night, showing which stage you were in at each point.
A night that looks fragmented is usually normal. Waking briefly several times is ordinary human sleep, not a fault in you or in the device.

The metrics beneath

Tap any of these for a sheet explaining it and where it came from.
  • Time in bed and total sleep — the second is always less
  • Efficiency — how much of your time in bed was asleep, typically 85%+
  • Time to sleep — how long you took to drop off. Always a dash on Apple Watch, because Apple does not provide it
  • Awake time — total time awake after first falling asleep
  • Resting heart rate and HRV for the night
  • Respiratory rate, and body temperature as a deviation from your own baseline

The Movements strip

Only if your source provides it, which currently means Oura only. It shows how much you moved through the night. If you use another device, the strip is absent rather than empty — we do not draw a chart of data nobody gave us.

SHI

Further down, if you have enough history: your Sleep Health Index — a four-week view rather than one night. It needs 14 usable nights inside a 28-night window. Until then it shows progress rather than a score, which is deliberate: an index built on five nights would be a number pretending to be a measurement.

Editing your sleep times

If the app got your night wrong — you were reading, not sleeping; you took the watch off at 6am but got up at 7 — you can correct it. The correction is yours, reversible, and stored separately from what the device reported. We keep both: what your device said, and what you say actually happened. The difference between them is exactly what we need to see, and one of the more interesting things you can give us.

Naps

Shown if your source records them. Never scored — they do not affect your sleep score or SHI. Scoring naps properly is deferred rather than done badly. Polar users will never see naps at all; Polar does not report them.

Ask Eir

The circular button gives a plain-language reading of the night. See Ask Eir.
