Changing Heart Rate Zones

I have been struggling with my Tickr correctly measuring my heart rate. I think it the bluetooth issue is resolved. However I just did a 4DP Test a few days ago and my heart rate was totally wrong, more than 20 beats per minute wrong. The problem I have is that now all of my heart rate zones during workouts are wrong. Can I alter the zones or do I have to do another 4DP Test to correct the zones?

If you go into the app, click on your profile (on Windows it’s your initial at top left, on Android it’s in “…more” then “Profile”), then “Athlete Profile” you can manually edit your cTHR value and hence update your HR zones.

Hope this helps.
