Apple Watch revealed alongside iPhone 6 and “revolutionary” mobile wallet

The iPhone 6 and 6 Plus are two new devices. The 6 has a 4.7-inch display, while 6 Plus has a 5.5-inch display – larger than the current iPhone 5 screen at 4.7 inches - and measures just 6.9mm and 7.1mm respectively in depth (the thinnest iPhones yet).

Thanks to the A8 processor the graphics are 84 times faster and processor performance is 50 times faster than the original iPhone.

In terms of design, the iPhone resembles the original iPhone with an all-metal back and glass that curves around the edges of the device. A further sign of Apple's move into the ‘phablet’ (phone/tablet hybrid) sector is the ability to use the phone in a landscape orientation.

Battery life has also improved with Wifi browsing up to 11 hours on the iPhone 6 and 12 hours on the 6 Plus.

Cook also announced a partnership with EE in the UK and T-Mobile in the US which will automatically allow users’ calls to be made over WiFi when the signal drops.

Meanwhile, the improved eight-megapixel camera has better focusing technology - the 'Burst' mode can detect smiles and blinks - and has optical stabilisation

Prices start at $199 and $299 in the US with the phone available on 12 September to ship on the 19 September.

Apple Pay

Built into the iPhone 6 is Apple Pay – a mobile payments platform using Near Field Communication (NFC) which allows users make payments in-store with one swipe.

Functioning via Passbook, users simply take a photo of their MasterCard, Visa or American Express cards using the iSight camera and upload to the Passbook app. Touch ID fingerprint sensors authenticate purchases and when a purchase is made a single-use code is generated. Cook explained this code is more secure than that on your credit card.

With privacy an obvious concern, Cook also noted that Apple won’t be able to track purchases such as how much you spent or with which retailer.

Over 20,000 merchants have signed up, with the likes of McDonalds, Bloomingdales, Macy's, Staples, Subway, Disney (its stores and the theme park) and Wholefoods announced as launch partners.

It will launch in the US in October; no date has been confirmed for a UK roll out.

Apple Watch

And finally, the Apple Watch was revealed.

Cook described it as “the next chapter in Apple's history” and stressed that it wasn't built as a small iPhone.

The design is sleek; like a classic analogue watch it has a small dial – a Digital Crown – on the side which is vital, acting as a type of mouse.

Instead of covering the screen wihen you navigate with your fingers the Crown allows users to scroll, select, and zoom. However, it does have a touchscreen function which enables users to similarly swipe or scroll as well as tap to access apps, make calls etc.

The Apple Watch relies heavily on Siri when it comes to composing messages on social media, texts or emails. However, there are pre-composed response options available as well as a variety of emoticons which Apple’s Kevin Lynch believes will revolutionise the way people communicate with each other.

Of course, as a "comprehensive health and fitness device" it also tracks your steps, heart rate, calories burnt and the frequency with which you sit up and down but will also “learn” your activity to set fitness goals.

The Apple Watch does however need an iPhone to run, using it for GPS and Wifi, but that means it is synced with Apple Pay meaning users can shop with the tap of a wrist.

Apple is sticking to its strategy of 'dearer is better' with the Apple Watch. The touch-screen device goes on sale early next year starting at $349.

That means the cheapest Apple Watch will cost more than Samsung Electronics' $299.99 Gear 2 smartwatch, which has a camera and music player and also responds to a user’s voice,
