## Description

VitalDial gives you one answer: are you ready to train hard today?

Eight peer-reviewed physiological models run simultaneously: HRV, resting heart rate, sleep debt, training load (CTL/ATL/TSB), acute-to-chronic workload ratio, VO2 max trends, Riegel race predictions, and critical speed. Together they synthesise into a single readiness score with a clear, unambiguous verdict.

No motivational nudges. No streaks. No "great job!" No guilt. Just signal.

WHAT VITALDIAL TRACKS
· Heart rate variability and resting heart rate
· Sleep duration, efficiency, and accumulated debt
· Chronic and acute training load from your workouts
· Acute-to-chronic workload ratio (injury risk indicator)
· VO2 max estimated from outdoor runs
· Race time predictions: 5K, 10K, half marathon, and marathon
· Critical speed from recent running efforts

All data comes from Apple Health. Works with Apple Watch, Fitbit (native sync), Oura, WHOOP, Garmin, and any wearable that writes to Apple Health. VitalDial never writes back. It's read-only.

ASK VITALDIAL ANYTHING
The built-in AI lets you interrogate your own numbers. Ask why your readiness dropped, what your training load trend means, or when you'll be ready to peak for your next race.
