Apple released its iOS 12 update at 10 a.m. PT on Monday, Sept. 17. Update your iPhone or iPad to iOS 12 right now.
If your iPhone, iPad or iPod Touch runs iOS 11, it will run iOS 12. That means all iPhones starting from the iPhone 5S onward.
Smoother and faster
The headlining feature of iOS 12 isn't something that can be explained through screenshots. It's something you have to experience on your own. Instead of cramming countless new features into iOS 12 and adding to some of the already perplexing (and frustrating!) bugs we all experience, Apple is using iOS 12 to focus on improving the overall performance of its iOS device lineup across the board.
Apps should open faster, scrolling should be smoother and crashes should be fewer.
Best new features
Siri gets smarter, but you'll work harder -- at first. Siri Shortcuts are tasks you can create and trigger with a custom command to do things like send a text, play a podcast and get directions to your favorite ice cream shop.
Cut down on screen time: New tools in iOS 12 show you how often you pick up your phone, how many notifications you receive, and how much time you spend using various apps. Trust us: It's scary to see hard numbers for how long you spend on your phone.
Better notification management: One of the main reasons we reach for our phones so often is the sheer number of alerts we receive. iOS 12 has new tools to cut back on unnecessary alerts.
Minor tweaks to Messages, but a big change to FaceTime: After a couple years of adding a lot to the Messages app, the biggest change this year is a new camera tool. FaceTime was supposed to add group calls for up to 32 people, but Apple decided to remove the feature from iOS 12 for the time being. We should still see group FaceTime later this year, though.
Create an Animoji of your own: Memoji is a word you're going to hear a lot this fall. A Memoji is an animated emoji iPhone X users can create and use just like last year's Animoji characters.
Closing apps goes old school: Apple changed the process of force-closing apps on the iPhone X, adding in extra steps. With iOS 12, things are getting back to normal.
You have a built-in tape measure: Need to measure a table or some other object? Apple is adding a new app, Measure, in iOS 12. The app uses augmented reality to measure real-world objects. It's pretty cool.
