The Garmin Connect app on iPhone shows HR in realtime.
Thanks! Will give it a try.
You’re welcome! Personally I prefer to minimize the battery drain on my phone, so I have a dedicated bike computer (Garmin 830) and a running watch (also Garmin) that shows HR. The recent Garmins (both watch and some of the Edge bike computers) allow you to download apps, and I installed a kayaking app on my watch. It keeps track of HR, distance, speed, paddle strokes, etc. I’d prefer to have a display in front of me, versus on my wrist, and I thought about using my bike computer on the kayak. But then I’d probably lose the paddle stroke metric, and the watch works fine for my use…
