Having read the OP's post and all the replies, this seems to be the best solution that I've read. I have used a strap based HRM for the last 10 years but would go this route if I wanted to use my Apple Watch as an HRM. However, I'm not too keen on using my watch as I really don't want to mess up the glass on a fall or crash. I'm wondering, though, does this require that the phone be in BTLE range for this to work? Nothing I saw on their website and video confirmed or denied that the phone must be present.
