The iOS 10.1 update addressed a lot of initial gripes with Apple's latest mobile operating system. However, it also introduced a glaring bug for some users: the Health app might not show your data, which is more than a little troublesome if you're a fitness maven or need those stats for medical reasons. Don't fret, though. Apple has released an iOS 10.1.1 update for the iPad, iPhone and iPod touch that makes sure you can see Health info. This is a relatively tiny update (the over-the-air fix is well under 100MB for many iPhone users), but it'll matter a lot if you're tracking step counts or calories with your Apple gear.
