Use heart rate monitors (HRM)
EXR connects to heart rate straps via Bluetooth and ANT+ and to smartwatches via Bluetooth.
Heart rate straps
Connect your HRM strap via Bluetooth or ANT+. Compared to ANT+, Bluetooth connections work with all and are usually stronger, leading to more precise data. Recommended HRM straps are the Polar H10, Garmin’s HRM-Pro™ and Wahoo’s TICKR.
Bluetooth
Connect your HRM in 3 steps:
- Activate your HRM's Bluetooth.
- Open EXR and click on the HRM icon. Select your HRM from the list and wait until you're connected.
- Select "Finish setup" to start your workout
ANT+
Please note that only Mac and Windows devices support ANT+.
Connect your HRM to your Mac or Windows device using an ANT+ dongle:
- Activate your HRM's ANT+.
- Open EXR and click on the HRM icon.
- Select your HRM from the list and wait until you're connected. ANT+ HRM's are indicated by their own icon
- Select "Finish setup" to start your workout
Trouble connecting while using a Garmin or Suunto program? It is possible that they prevent EXR from finding your dongle. Please contact your program’s developers to find a solution.

Smartwatches
Many smartwatches work with EXR. Often, a third-party heart rate app is needed to connect with EXR via Bluetooth. For example, smartwatches like the Galaxy Watch and the Apple Watch connect through third-party heart rate apps which can be found in the App Store and Play Store.
