The latest version of Apple's iPhone and iPad operating system iOS 11 will be available for users to download from today.

The software, which will be available on its new iPhone 8 and iPhone X smartphones, includes a host of upgrades including phone-to-phone payments and a "do not disturb while driving" mode.

Here are the 11 best features in the new iOS:

Phone-to-phone Apple Pay

Apple is adding a highly anticipated feature to Apple Pay, its payments system, that allows users to pay one another within iMessage. The peer-to-peer payments can be made and verified through biometric security, such as Touch ID or Face ID. The service will be available across iOS devices and the Apple Watch

Redesigned control centre

Apple is refreshing its iPhone Control Centre in iOS 11. The redesign has a simpler look, fitting on a single page with sliders and key functions and added customisation options.
