Is the iOS step counter accurate?

Sorry I’m not sure if there’s an actual name for it, but it’s in an app called Fitness on my iPhone.

Apparently, I’ve done just over 17,000 steps today which is equivalent to just over 12km.

I have been on my feet a bit today, but I’m not sure how I’ve walked 12km? It doesn’t feel like I have.

is it accurate? Or does it have a tendency to be inaccurate?

I generally find mine to be quite accurate and tally's with my friend's pedometer fairly well. The measure of the distance I've walked tends to tie in well with reality as well (sometimes I've checked it agains my tracked journey on Google maps or I know the distance of local walks etc.)

Having said that, I'd expect you to realise you've walked a lot today if you've done 17000 steps!
