Your 40 miles this week hit like 55. RunIntensity is the running app that knows the difference. Distance and pace don't tell you how hard a week really was. A hilly run in the heat or a tempo on tired legs costs more than the mileage suggests. RunIntensity scores every run in Stress-Adjusted Miles (SAM), a five-factor training load model built from heart rate, terrain, surface, cumulative fatigue and conditions. Your weekly mileage becomes a weekly training load you can plan around. TWO NUMBERS, ONE ANSWER EVERY MORNING RunIntensity reads what your watch already writes to Apple Health and scores two things separately, 0–100: • Recovery — heart, nervous system and sleep. HRV, sleep and resting heart rate against your own baseline. Snaps back overnight. • Freshness — muscles, tendons and joints. How much of your recent training your legs have absorbed. Drops with a hard session, climbs back over hours or days. Then one call: Ready, Steady or Recover. Ready only when both are high; Steady when one system is still catching up; Recover when rest is the workout. Recovered isn't the same as healed — this is the app that knows when you're overdoing it. KNOW WHAT TO DO TODAY Your verdict, today's workout, your weekly training load budget and a one-tap start. Widgets, Siri ("What's my readiness?") and Control Center keep it one glance away. FREE FOR EVERY RUNNER • Stress-Adjusted Miles — the real cost of every run • Recovery, Freshness and a daily Ready / Steady / Recover verdict • Weekly SAM budget with mid-week pacing tips • 26-week training load charts • Training planner with periodized phases and race milestones • Personal records and trophies • Shoe mileage tracking • Body soreness tracker — spot patterns before you overdo it • The peer-reviewed research behind every number • Your own training on the web dashboard at runintensity.com/coach WORKS WITH ANY WATCH Apple Watch, Garmin, COROS, Polar and more — any run that syncs to Apple Health flows in automatically, duplicates merged. No manual logging. APPLE WATCH APP • Workouts from your wrist with live heart rate, pace and distance • Race Pace interval timer with custom segments and repeats • Complications and Watch widgets with Recovery, Freshness and today's verdict • Live Activity on the Dynamic Island during workouts FRIENDS & THE BOARD — FREE See how your friends are training: readiness, training load, workouts, reactions, weekly leaderboards, head-to-head challenges and streaks.
