Today's Workout: Readiness

Wake up knowing how much to move today.

Today's Workout compares the sleep, heart rate, heart-rate variability, breathing rate, and wrist temperature your Apple Watch recorded overnight against your personal baseline, rates your condition on a 1–5 scale, and suggests a workout type and duration to match.

FEED — YOUR MORNINGS, ON THE RECORD The home screen keeps a running feed of what happened: today's score, workout celebrations, and — when your level changes during the day — why it changed ("more sleep data came through, so the ceiling on your score lifted"). No more silent number changes.

TODAY'S CONDITION A 1–5 rating built from sleep, HRV, resting heart rate, breathing rate, and wrist temperature — each compared against your own baseline, not population averages.

TODAY'S WORKOUT A metric briefing plus a concrete suggestion: minimum (WHO daily share), optimal (matched to your condition and training load), and this week's remaining headroom. Every number is derived from published research, and Settings > Methodology lays out the evidence and its limits.

PAST 7 DAYS Sleep chart and workout summary — days without data are shown apart from rest days.

PRIVATE BY DESIGN Your health data never leaves your device. All computation happens on your iPhone; our server stores only account info (email, display language) and, if you turn them on, error reports — which never include health values or scores. Every analysis feature works without an account.

Requires an Apple Watch for overnight measurements (sleep, HRV, wrist temperature).

Today's Workout is not a medical device and is not a substitute for medical advice. Scores and guidance are wellness information to help you choose workout intensity and rest.
