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.
Free: 7 AI questions per month (Gemini)
Pro £4.99/mo: 150 questions per month (Claude)
Elite £7.99/mo: Unlimited monthly questions, fair-use daily limit (Claude), plus Connect to Claude
CONNECT TO CLAUDE (ELITE)
Link VitalDial to your own Claude account and ask Claude about your recovery, training load and plan in any conversation. It's opt-in and read-only, shares derived daily scores (never raw health data), and you can disconnect at any time, which deletes everything shared.
YOUR DATA, YOUR DEVICE
Your health data is never sold and never used for advertising. It only leaves your phone when you choose: an AI Coach question, a Fitbit sync, or Connect to Claude. No nudges, no streaks, no social features.
iOS 17 or later. No Apple Watch required.

Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
Training plans now use your real paces. Enter a recent race time, or let VitalDial work them out from your runs, and accept updated paces as you get fitter.
Set your starting point: your current weekly distance, your longest run, and the shortest run you want in the plan.
The long run now builds towards race distance and eases off properly in recovery weeks. Race eve is a short shakeout.
Today now matches its own advice: when your training load is high, the header tells you to ease in rather than go.
Fixes: today's session no longer shows as done on a new plan, editing a plan keeps your settings, deleting a plan refreshes Today straight away, and the Fitness vs Fatigue chart now draws correctly.
