Apple is believed to be secretly developing a ‘smart watch’ with a touchscreen. Chinese online sites have reported the computer giant is working with chipmaker Intel on a wrist-worn gadget that has a 1.5inch screen and uses Bluetooth to communicate with other gadgets, which could include an iPhone. The ‘iWatch’ will go on sale next year, the report claims. It is believed the iWatch will run a version of iOS, the same software as the iPhone and iPad, allowing apps to be easily downloaded. Releasing a watch could also help it compete with Google, who claim they will release ‘Google Glass’, a headset with a screen, next year.
