FTMS Treadmill Intervals
Your treadmill on autopilot
Free · Designed for iPhone. Not verified for macOS.
Press Start and your treadmill runs the workout: speed and incline change for every interval, from 4×4 sprints to steep incline walks, with heart rate from Apple Watch.
Turn your treadmill into an interval coach. Build a workout once, press Start, and FTMS Treadmill sets the speed and incline for every step while Apple Watch tracks your heart rate.
BUILT FOR INTERVALS
• Warm-up, work, recovery and cool-down steps, with repeat blocks
• Keep a step's speed and incline steady, or change them gradually: a progression from 8 to 12 km/h, or a climb from 1 to 6 %
• Start from a template: Norwegian 4×4, 30/30 Intervals, Hill Pyramid or Easy 30
• Plan runs or walks, steep incline walks included
YOUR TREADMILL ON AUTOPILOT
Connect a treadmill that supports Bluetooth FTMS (Fitness Machine Service) and the app changes its speed and incline as each step begins. Change them on the console and the app keeps your setting for the rest of the step. Stop the belt and the workout pauses. The belt only starts when you tap Start or Resume.
No Bluetooth treadmill? Manual mode tells you what to set and when.
HEART RATE FROM APPLE WATCH
• The watch app opens on its own when the workout starts
• Live heart rate and zones on your iPhone, your watch and the Lock Screen
• Zones from your Health settings, from your heart rate reserve, or set by hand
• Pause, skip a step or add 30 seconds from your wrist, with a tap on the wrist as each step begins
STAY ON TRACK
• Spoken cues for every step, with a 3-2-1 countdown
• Live Activity and Dynamic Island with pause and skip buttons
• Extend or skip any step mid-workout
• km/h or mph, speed or pace
SAVED TO FITNESS APP
Workouts are saved to the Fitness app as an Indoor Run or Indoor Walk, with each step as an interval, kilometre or mile splits and elevation, plus heart rate and energy when Apple Watch tracks them. They show up in Fitness next to your other workouts. Distance comes from the treadmill's belt, or from Apple Watch if you prefer. Prefer Apple's Workout app? Turn off saving and watch tracking, and a countdown lets you start both at once.
A SUMMARY AFTER EVERY WORKOUT
Heart rate, speed, cadence and elevation charts lined up with your steps, time in each zone, a row per interval, splits, running form, and the treadmill's distance next to the watch's. Every finished workout is kept in History.
