I really like this watch face. It has a lot of useful information and is very legible. Not sure what it's going to do to the battery life (this is on a Fenix 5 X Plus) but I am more than willing to try.
One suggestion: I wish there was a way to have a fixed scale for heart rate. I am not really interested to know when my heart rate changes from 50 to 70 and it is distracting to see wild variations on the plot when the heart rate actually changes little. I would prefer a fixed scale (user adjustable in the settings), defaulting to 50-150 for instance. Then I could tell at a glance when I my heart rate is getting high (I am older)
Edit: sorry for posting in the wrong forum and missing crucial information. This is about the Data Lover watch face, installed on a Fenix 5X +. The developer is Peter Dedrucker.
