It would be great if it was accurate. How accurate is this data?
- tomnipotent 6y agoDoesn't need to be accurate, just consistent in its inaccuracies over time. It's about changing behavior, not diagnosis.
- justusthane 6y agoI have an Apple Watch and iPhone and use all the health tracking stuff. I’m a little bit suspicious of the accuracy of sleep tracking, but so far I haven’t had any experiences to suggest that it’s not reasonably accurate. And there’s no reason to believe that heart rate and step counting isn’t extremely accurate—seems fairly trivial to measure.
- gumby 6y agoBeing consistent is almost as good — essentially as good in fact. I have a glucose meter that’s quite wrong, but the shape of its curve isn’t bad (the error isn’t linear, but is consistent— around 100 it measures about 82; at 150 it measures 130) but now I’m used to it it tells me what I need to know. And the strips are cheap. I don’t need the watch to tell me if my heart rate is too high but it’s useful if it tells me my heart rate was about the same the whole run.
