VitalDial: HRV & Recovery

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. TRAINING PLANS THAT READ YOUR BODY Set a goal, from a first 5K to a marathon, and VitalDial builds a plan from your real fitness. Each morning it checks your recovery and adjusts: easing off when you need it, moving sessions when you miss one. WHAT VITALDIAL TRACKS · Heart rate variability and resting heart rate · Sleep duration, efficiency, and accumulated debt · Training load from every workout, including walks, classes and weights without heart rate (estimated from the activity, or rate the effort yourself) · 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 Works with Apple Watch, Fitbit (native sync, including your workouts), Oura, WHOOP, Garmin, and any wearable that writes to Apple Health. VitalDial only writes to Apple Health when you connect Fitbit, adding your Fitbit sleep, HRV, resting heart rate and blood oxygen so they sit alongside everything else. 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.
