RunIntensity calculates your true training load using Stress-Adjusted Miles (SAM) — a 5-factor model that accounts for heart rate intensity, terrain, surface, cumulative fatigue, and environmental stress. Stop guessing how hard your runs really are. WHAT MAKES IT DIFFERENT Most running apps track distance and pace. RunIntensity goes deeper. A hilly trail run in the heat stresses your body far more than an easy road jog — even at the same distance. SAM captures that difference so you train at the right load every day. KNOW WHAT TO DO TODAY The readiness-first "Today" home gives you one clear answer every morning: push or recover. Readiness score, today's planned workout, your weekly training budget, and a one-tap start — all at a glance. HOW IT WORKS RunIntensity reads your Apple Health data — runs, heart rate, HRV, resting heart rate, sleep, and weight — and computes a daily readiness score and weekly SAM budget. No manual logging. No wearable lock-in. If your watch writes to Apple Health, RunIntensity can use it.
