Hello. I'm rather new to fitness watches and so just getting the hang of it. I apologise if this is something obvious.
I have been using a Vivosmart HR (purchased reconditioned from Amazon) and have connected it via Bluetooth to my phone with the Connect app.
All the stats seem to match up on my phone and the watch apart from the HR. My phone displays a completely different resting and max heart rate to my watch. Yesterday I did some exercise and reached 155 HR but my max heart rate on the phone stayed at 130 (from exercise earlier in the day).
I think it might be something in doing wrong as also on the watch alone, it says didferent HR reading to the ones I observe whilst I'm exercing.
Unless it's just not working (not sure how well they check the reconditioned ones) and I'm flogging a dead horse here.
I've contacted Garmin support and they just told me to "monitor it".
Any advice would be most welcome, thank you.
