Demo — simulated data, not a live account
Readiness score
Good last night was 0.5h under your usual
From resting HR, sleep and HRV. SpO2 isn't a meaningful daily-effort signal on its own; respiratory rate isn't exported yet.
Sleep score
Good 6h 36m last night
From last night's duration against 7h, and consistency over 14 nights.
Resting HR
your normal today 46-50 bpm
Sleep
your normal today 6.2-8.0h
HRV
your normal today 34-50 ms
SpO2
your normal today 95.0-98.2%
Respiratory rate
Not exported yet — add Respiratory Rate in Health Auto Export. See Settings.
Biological age
VO2 max and HRV are exported now, but there's no designed formula behind this number yet - showing one before that exists would just be a guess dressed up as a measurement.
VO2max
Apple Watch's own estimate, not a lab test — a rough trend, not a precise number. No population Good/Fair rating shown; that needs an age/sex-matched reference table this doesn't have yet.
Resting heart rate48 bpm 7-day
dashed = your rolling 14-day median (currently 48 bpm) · shaded = rolling normal, median ±1.5 MAD (currently 46-50 bpm)
Sleep 6h 36m last night
shaded = rolling normal, median ±1.5 MAD (currently 6.2-8.0h) · amber bars fall outside that night's own rolling band
