I have a vivomove HR watch that gives me very inaccurate heart rate readings. I bought an external garmin HR heart strap monitor and now realise the two devices don't sync?! Will I have better luck with my older Garmin watch - the Vivoactive HR sports watch?
I just want to wear the external heart rate strap during HIIT workouts - if it won't sync with either of these watches which app would you recommend to gather the heart strap info. one that ideally links to Discovery vitality
thank you
