		busymom0 on Feb 13, 2025 \| parent \| context \| favorite \| on: Self hosted FLOSS fitness/workout tracker What sensor would you recommend? I have tried Apple Watch and i really only care about the heart rate. But it doesn't poll the heart rate constantly unless in exercise mode. I wish I could just constantly track the heart rate every second.

I use the basic garmin chest strap. It transmits continuously and supports things like HRV, which I suspect is a secondary high data rate mode.
