Now we know how Apple will make the iWatch into the ultimate fitness device

It’s been a big news week for Apple’s iWatch and now 9to5Mac’s Mark Gurman has weighed in with a new report that claims Apple has been working with several professional athletes — including Lakers star Kobe Bryant, Los Angeles Kings right winger Dustin Brown and an unnamed member of the Boston Red Sox — to make sure the iWatch can hold up under the most strenuous of conditions. Gurman says that these athletes have been testing out all aspects of the iWatch, including widely expected features such as its heart-rate monitor and its step tracker, as well as other features that “read a person’s hydration levels, blood pressure, and sweat.”

Apparently the iWatch isn’t just expected to be for jocks, however — one of Gurman’s sources also says that the device will be sold as a “fashion accessory” that will feature an “elegant design” that should appeal to both gadget geeks and celebrity athletes. Gurman also reports that the device will run a “variation” of iOS 8 and will feature “advanced maps functionality,” likely through Apple’s own mapping service.

What’s interesting about Gurman’s newest report is that he still doesn’t have an exact size yet for the iWatch and says its display is currently “rumored” to be between 1.5 inches and 2.5 inches. This suggests that Apple is either planning on releasing two watches that come in different sizes or it’s still undecided of the final size the iWatch’s display will take.
