02 What VitalDial tracks

Five instruments. One read.

Click a metric to bring up its panel. Each panel is the actual app screen, not a marketing mockup.

03 How it works

Ingest, model, verdict: no black box.

Every coefficient is exposed in-app. Every transform is documented. If you'd like to argue with our model, you can, and you'll have the references to do it.

04 Race intelligence

Your current fitness, adjusted for today's fatigue.

Not a calculator. A verdict.

Predictions update daily using your full quality run history and current TSB. Confidence tiers automatically: high at 15+ quality runs, medium at 8–14, low below that.

05 Pricing

Three tiers. No usage caps.

All plans include full Apple Health sync, so VitalDial works with whatever you wear: Apple Watch, Fitbit, Oura, WHOOP, Garmin, and more. Free is genuinely useful, not a trap.

06 Ask VitalDial

Anthropic Claude, grounded in your actual data. Not generic advice.

Claude on Pro and Elite. Gemini on Free. 100% private. No raw health data leaves your device: the query carries only the computed metrics relevant to your question.
