Garmin has released sport watches and wrist-based fitness trackers with built-in optical heart rate monitors.
These units are able to broadcast heart rate data using ANT+. Our Group Fitness application support them.
If you have a Garmin VivoSmart HR, a Garmin 735xt, a Garmin Fenix HR or any Garmin sport watch with optical heart rate monitor, you can use it with the Group Fitness app.
Remember to enable the unit to broadcast the data, see our blog post: Group Fitness and Garmin VivoSmart HR
