Review: WatchOS 2 offers timely (and needed) tweaks

Michael deAgonia | Sept. 22, 2015
Native apps, new watch faces make the Apple Watch more useful.

And that hasn't changed. When using the heart rate tracking feature, the watch starts off accurately enough, but within 15 minutes, heart-rate tracking is all over the map. Even after updating to the final version of watchOS 2, I found that for most of my workout, the heart rate readings were still either way off or just stuck on scanning.

Because the watch is unable to accurately track heart rate with this activity, the calories-burned counts are off; that's frustrating when you're trying to track calories and make a goal -- and those interested in the Watch for fitness should take note.

Bottom line

WatchOS 2 brings improvements to the Apple Watch in some useful and surprising ways. While I expected the new version to speed things up and add some needed refinements, I didn't expect Apple to include Nightstand mode or Time Travel.

Of course, watchOS remains a work in progress; I don't see the device truly maturing for a couple more software and hardware generations.

That said, for current watch owners, watchOS 2 improves almost every aspect of the device. And it's worth the price of an upgrade -- which is free.
