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.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
VitalDial now gives you the verdict at a glance, then lets you tap in for the detail only when you want it. We simplified the Today and Metrics screens: a clear readiness verdict up top, and you tap any dial or card to see the science behind it. Light mode is brighter and easier to read. As always, eight peer-reviewed models, one honest answer, every morning.
