What do I need to use ZoneRun?

A treadmill that supports Bluetooth FTMS (Fitness Machine Service) and a Bluetooth heart rate monitor, such as a chest strap or arm band.

My treadmill doesn't show up

Make sure Bluetooth is on and the treadmill isn't connected to another app, such as the manufacturer's app, Zwift or Kinomap. Close those apps, then tap Scan on the Connect devices screen. Some treadmills only advertise Bluetooth while their console is awake.

The speed doesn't change automatically

Your treadmill must allow speed control over FTMS. ZoneRun shows "speed control" under the treadmill name when it does. Some treadmills need you to press start on the console before they accept speed changes.

Why are workouts locked?

ZoneRun needs one calibration run to learn your speed in each heart rate zone. Start it from the Run tab. It takes 25 minutes: 5 minutes in each zone.

How do I change my heart rate zones?

Go to Profile › Heart rate zones. Set your maximum heart rate to reset all zones, or adjust each zone on its own.

My runs aren't in Apple Health

Open Settings › Health › Data Access & Devices › ZoneRun and turn on all categories.

Is it safe?

Your treadmill's stop button and safety key always take priority. If the belt stops, the safety key is pulled or the treadmill disconnects, ZoneRun stops controlling the speed until you resume.
