1. Interactive Notifications
Interactive notifications is one of the best parts about iOS 8. You can respond to texts, email, calendar invitations, reminders and messages within apps such as Facebook from the notification banners that pops up at the top of the screen.

For the first time, you're no longer restricted to the keyboard Apple gives you and can pick better options from third-party developers, like Swype. Available for $0.99 in the Apple App Store, there's a reason why Swype is the number one paid app right now: instead of tapping letters, you can swipe your fingers across the keys. There are Here are some other keyboard alternatives to try out with your keyboard on iOS 8, such as SwiftKey and Fleksy, but if you don't want to download an app, Apple made improvements to its own. The built-in keyboard now offers predictive text, giving you word suggestions before you even type anything.
4. Camera Timer
Selfies are much easier to take with iOS 8. Apple added a timer to its Camera app, allowing you either 3 or 10 seconds to get the shot exactly how you want it. You can also prop up the device before setting the timer, so you don't even need your hands to take a picture.
5. Landscaped Homescreen

6. Key People Shortcut
If you press the Home button twice, you'll not only see the webpages you have open but the faces of people you've recently talked to. This makes it easy to call or text your favorite contacts right away. The down side, however, is that it highlights contacts you might not want others to know about, too. For example, if you've deleted a conversation you recently had with an ex (and you don't want to broadcast this to anyone looking over your shoulder), their name will still display on the top. To remove this feature, visit Settings > Mail, Contacts, Calendars > Show in App Switcher and switch it of Off.

Meanwhile, dragging your finger slowly on a message (displayed in the Mail app) will let you flag or archive it. Swiping to the right will reveal the feature to mark a message as unread.
9. Multitasking Email
At long last, emails are now windows, so you don't have to close one to open another. Users just swipe downward to minimize the email and it's possible to open up a few at once, if you want to look at them in carousel form and pick which one you want accordingly.
10. Smarter Spotlight
Spotlight — which is still accessed by dragging the top of the screen downward — is a significantly smarter search tool than ever before. In addition for looking for stuff on your own device, it now searches Wikipedia, knows what topics are trending online in real time, shows you restaurants nearby and tells you movie showtimes.
11. Share Location
If you're planning to meet up with friends, you can now share your exact location with them. iOS 8 lets you set up a window for when you want whereabouts shared, too — for example, if you're be at the beach from noon to 4:00 p.m. ET, you can share your location with a group of friends until you're ready to head home.
12. Audio Messages
For times when you want to send a quick voice message, but don't really want to get into a conversation over the phone, you can now record and send audio snippets via text message. Use case scenarios: singing Happy Birthday or wishing someone good luck for a big meeting.
