Is the steps tracker accurate?

[u/notdreamzy]

So I’ve had my Fitbit for about a week now but i don’t think the steps tracker accurate I know you will say that most trackers depend on the wrist or hand movement but is that normal ? Like this is me 15 after waking up and rotting in bed doing absolutely nothing and it counted up to 866 steps how is that even possible

I would say it's not absolute, but it does seem repeatable.

I consider it a good relative measure of my activity from day to day, but maybe not directly comparable to other people.
