All functions work as expected. It tracks my steps to a 95% accuracy. I have tried it on while walking and running and counted my steps manually to cross check. And the tracker is surprisingly accurate. Even sleep tracking works seamlessly. It’s been 5 days and till now it has always recorded bed times perfectly!
I also love the way it lights up on double tap! The alarm and misfit move features are handy. I’ve even tried linking it to the link app but didn’t like any of the possibilities there.
