Run.IQ

How fast are you really going? Run.IQ turns your iPhone and Apple Watch into a precision speed and performance lab for every way you move. Built for athletes who want real numbers, not guesses. Run.IQ delivers live GPS telemetry — speed, distance, altitude, elevation gain, heart rate, and blood oxygen — across four activity modes tuned to how you train. Sprint, Run, Walk, Bike, or Ski/Snowboard — each mode has its own calorie model based on your body weight, so your stats actually mean something. Watch your live speed gauge and route map update in real time as you push your limits. Go phone-free with the Apple Watch companion. Track sprints with heart rate and blood oxygen right from your wrist, then get instant sync back to your iPhone the moment you finish. Hitting the mountain? Ski mode automatically detects your runs, tracks vertical stats, and puts 212 ski resorts at your fingertips — from New England, Colorado, Utah and Washington to Québec, the Alps, Japan, Australia, New Zealand and South America. Live weather — temperature, wind, humidity, fresh snow — keeps you dialed in for every session, in every mode. Competitive by nature? Create a Squad, invite friends with a code, and go head-to-head on a leaderboard for distance, speed, and calories burned. Set custom target distances with auto-stop, review detailed post-session summaries, and build a full history of every effort. Download Run.IQ now and start tracking speed like the athlete you are.
