Thanks for sharing. I've been dealing with health problems since a covid infection and have been experimenting with breath work. I haven't been able to find something that shows raw, realtime HRV data like this. I tried a HeartMath product at some point, but it was unclear what exactly it was showing and I didn't find it helpful.

The Polar H10 connects to your computer via Bluetooth?

Interesting, thanks for sharing. It's cool they do it as a platform, but I'm not sure what the benefit over using a Polar H10 would be, which are widely available, I guess it would be custom branding of the hardware
