We know that the iWatch will take full advantage of HealthKit, the suite of fitness tracking software revealed by Apple at the recent unveiling of iOS 8. Apple is targeting FitBit, Nike and Samsung to become the go-to gadget for health-conscious people.
It's also been confirmed that the iWatch will contain NFC (Near Field Communication) technology. This hardware has been available for a long time in many Android devices, but it will be a first for Apple. NFC allows for fast mobile payments and data transfer between nearby gadgets. This could mean that the iWatch will be able to be used as a mobile credit card. It could also be a big part of Handoff, the software system built into iOS 8 and OS X Yosemite to allow all Apple computers to communicate seamlessly with each other.
The iWatch will also have some method of wireless charging, but it won't be solar. Apple reportedly experimented with solar techniques but they didn't end up in the final product.
It's also believed the iWatch will come in two different screen sizes, just like the iPhone 6. Click here to learn what we know so far about the next iPhone model.
