@colleenyoung. I original got the Fitbit to track my HR more than my steps. I'm having alot of issues with my fitbit:

One night I had a restless night, woke up at midnight and could not go back to sleep until at least after 1am. The next morning, I found I got a 90 in my sleep score! Another night I thought I slept well, but only get a 67 because it did not record my sleep for a few hours during the night.

I always use the same route for walking so I know how many steps it would be, but lately it was about 300 steps less. So I decided to use Google fit too when I walk, sure enough, the difference is about that much. My fitbit is on my wrist 24/7, except when I charge it or bath time. I do not carry my phone with me during the day, so I don't understand why at the end of the day, my Google fit showed I walked more steps.

I still use it to track my HR when I walk as this is primarily why I got it but my cardiologist dies not think that fitness tracers are always correct.

Now instead of counting steps, I use the mileage feature. Shopping for a new fitness tracker. Now that Google has completed the purchase of Fitbit, maybe they can iron some kinks out as I think it is a useful tool to get me motivated.
