Apple announced iOS 11 at today's WWDC keynote, including big updates to Messages, Apple Pay, Siri, and more.

Messages will revise the App Drawer for easier integration with apps like Stickers, and iCloud will auto-sync messges between devices for smaller and faster backups. Apple Pay gets into the payment sharing business by allowing person-to-person payments, with integration with iMessages for easy sending and receiving. 

Photos and the camera got some large updates. Memories has smarter tags for grouping events together, and Live Photos can be trimmed, and feature effects like looping or bounces. You can also create a Long Exposure with an option in the camera menu. Both photos and videos will be getting better compression for lower space requirements on your device and iCloud. 

HomeKit will add speakers, and Music will feature a Friends section to see what your contacts are up to. Apple Music will also integrate with third-parties like Nike, Anchor, and Shazam.

The underlying mechanics of iOS are undergoing some changes too. The Lock Screen and Notification Center are the same screen, and the Control Center has been revised to be a single page. Small windows in Control Center can be enlarged for more options using 3D Touch. Siri will now have a male voice and translation function, and Siri Intelligence will use machine learning to better predict what you need next. 

As a safety feature, you can turn on "Do Not Disturb While Driving." If the device detects that you're in a moving vehicle, the screen will remain black without any notifications, and if you try to turn it on it will remind you not to fiddle with your phone while driving. You can dismiss it by confirming that you're not driving.

Apple also revealed that it has revamped the App Store UI for iOS 11.
