TreadPath 1.2 brings interval training, a live view on your iPhone, and a smarter watch workout. INTERVALS • Build an interval plan right on your watch: distance segments with a target speed and incline, repeated for as many rounds as you like. • Your wrist taps you at every change, and a full-screen card shows the next speed, incline and distance. • Optional voice cues read each change aloud: "Hit 6 miles per hour at 1 percent for 0.25 miles." • Connected to a Bluetooth treadmill? If the belt doesn't follow a change, TreadPath switches to an open run so your stats stay honest. LIVE ON IPHONE • A new Live tab mirrors your watch workout in real time: time, distance, pace, calories, cadence, heart rate zone and your current interval, sized to read from a docked phone. • A 400 m track shows where you'd be on each lap, with a lap timer in the middle. Pick clockwise or counterclockwise in Profile. • Live Activity on the Lock Screen and in the Dynamic Island, starting automatically when you begin a workout on the watch. SPLITS & PACE • Each mile or kilometer brings up a split card with that mile's time, and splits are listed on your summary. • Current pace on the watch, and average pace for every workout in History. MORE • Setup remembers your last speed and incline. • Accidental starts with no distance are no longer saved to Health. • Fix a workout: swipe any workout in History to correct its distance and calories. • Dark mode by default, with Light and System options in Profile. • Improved reliability when saving workouts to Health.
