In the power, cadence and heart rate data box at the top left…
The heart symbol and ‘BPM’ text could change colour to show what heart rate zone you are in. At the minute, I look at my watch for this info (bit tricky when on the aero bars and rollers!), so having it right there on the screen would be really helpful.
Should be quite an easy enhancement to make?
I just came to make the same suggestion. I’m a little concerned reading yellow or green text may be hard for some folks. I suggest instead they change the color of the heart picture itself, not the actual BPM value.
Maybe just display the heart rate zone number?
Agree. Change the layout or background to show that either in the chart/graph or the background colour of the heart and/or heart rate.
