The heart rate recording works perfectly on the indoor bike and the values match the values on my Apple Watch exactly. Because I don't think the watch records my heart rate correctly when swimming, I bought the heart rate strap. It said it works for swimming. In the outdoor pool, as soon as I got into the water, it immediately lost the connection to my smartphone. No heart rate was recorded. Indoors, it measured just 10 minutes out of 75 minutes of training and was certainly wrong - far too low. Hence my question - am I doing something wrong or is it simply not working?
