RunReady gives you one honest answer every morning: are you actually ready to run today? It reads four signals from your Apple Watch overnight — resting heart rate, heart rate variability, respiratory rate, and last night's sleep — and compares them against your personal 30-day baseline. Then it gives you a single readiness score from 0 to 100, color-coded green / yellow / red, so you can decide in three seconds: push hard, ease back, or take the day off. Why use it • A 30-day rolling baseline learns YOU. No "average runner" tables. • Single-indicator overrides catch high-conviction signals. RHR up 12%? You'll see caution even if everything else looks fine. • Override-aware AI insights explain WHY today's score is what it is, in plain English. Generated locally on-device with Apple Intelligence — your health data never leaves your phone. • Pre-run pace advisor recommends an effort target (easy / steady / interval) based on your readiness AND training load. • Recovery card after every run: HRR, RHR drift, HRV recovery — see when you're back to baseline. • Race time predictions based on your recent pace and VO2max. • Apple Watch app + complication: glance to see today's readiness without taking your phone out. • Home screen widget for the same. Privacy • Everything runs on-device. No accounts, no servers, no analytics. • HealthKit data stays in HealthKit. RunReady reads it; we never store it elsewhere. • AI explanations use Apple's on-device Foundation Models (iOS 26+) — no cloud calls, no data sharing. Built for runners who want signal, not noise.
