iOS 10 The world’s most advanced mobile operating system.

Easy to Use
From the moment you pick up your iOS device, you’re up and running. Tap your favorite app and get right to work — or play. Swipe from the right side of the Lock screen to quickly pull up your camera. Scroll through thousands of photos in seconds. Everything about iOS is designed to look beautiful and work beautifully.
So smooth and responsive you won’t even notice it. And that’s the point.
Because iOS is engineered specifically for iPhone and iPad, everything looks and feels incredibly fluid. iOS uses a framework called Metal to maximize graphics performance. Whether you’re surfing the web, moving from app to app, or playing the most complex 3D video game, the graphics and responsiveness are amazingly smooth. No other mobile operating system is so effortless and natural.
An OS with a remarkably high IQ.
With sophisticated features like proactive(积极主动的) suggestions, predictive typing, and everybody’s favorite personal assistant, Siri, iOS 10 makes everything you do easier, quicker, and more fun.
Nobody understands you quite like Siri.
Siri learns how you talk, not the other way around. Thanks to Apple-developed machine-learning technology, you can simply speak naturally. So whether you say “Get a Lyft to SFO” or “I’d like a ride to SFO using Lyft,” Siri will read you loud and clear.
Siri even works with your favorite apps.
You can ask Siri to send someone a payment using Square Cash, book a reservation through OpenTable, and much more. And the number of apps incorporating Siri is growing every day.
