Zone 2 app
Hi what’s a good zone 2 cardio app please? I have a polar H10 strap and the polar flow app doesn’t give time in zones well you believe? It just gives them at the end. The polar beat app does but you can’t edit THEIR selected zones. My zones are different to theirs so I’m in a pickle here. I would like to use my H10 polar strap for accuracy and not my Apple Watch. Thanks.
