Fitbit Versa 2 heart rate

[TJ74]

I usually would wear a heart monitor and when walking my pulse wouldn’t go over 125 unless I going uphill or running intervals.  I just got a Fitbit and as I was walking my pulse was 120 then all of a sudden 145 then 111 then 135.  I don’t think it wouldn’t fluctuate like that.  And I didn’t feel any more or less tired.  I felt my pulse and checked it with a stop watch and it wasn’t ever at 145.  Is their and inaccuracy?  I noticed both times it said 145 I was in the same area.   Like maybe interference?  It seems normal when resting but this morning it said 153....when I timed it manually it was 80.

Hello @TJ74, welcome to the Fitbit Community forums. Sorry for the late response. 

Thank you for sharing this information about your heart rate information not being accurate. 

Before considering other options, I would recommend to try performing a restart and to follow all the instructions in this article to improve the accuracy of heart rate information: How to I improve the accuracy of my heart rate rate reading?  This has been useful to other users who have experienced something similar. 

Then check how your watch is measuring your heart rate on the following days. 

Please keep me posted on the outcome.
