1.Control Center : Apple has introduced a translucent slide-able window which allows one to toggle certain settings like brightness, volume, Wi-fi, Airplane mode and Bluetooth, from anywhere on in the phone. The Control Center even offers a flashlight, along with tabs for music, camera, and other quick-access apps. All you have to do is slide up from the bottom edge of the display.
2.Multitasking : The double-tap, which earlier revealed only an icon list of apps that were functioning, now seems to offer live previews. iOS 7 now enables developers to add a new multitasking option in their apps. However, iOS will determine what apps users use frequently and will update them according to that frequency. While it isn’t absolutely clear at the moment, iOS will also update apps at “opportune” times when the radio is anyway awake.
3.Safari : The web browser gets the full-screen mode and a smart search field, just like the Google Chrome in Android. Tabs too get a new UI with all the tabs now stacked in a vertical manner and unlike before when Apple only allowed eight tabs, now users can open and switch between unlimited tabs. The iOS 7 version also gets the iCloud Keychain feature to keep user’s sensitive information safe and at hand.
4.Camera : The new UI that lets users swipe between various camera types, such as panorama or HDR. The Photo gallery too has been given an overhaul with photos now automatically categorized and organized according to moments based on date, and location. Users can use AirDrop to share photos and videos on their gallery as well as share their photo streams with others in a new feature called Shared Photo Streams.
5.AirDrop : With AirDrop users can share photos via iCloud on Photo Stream seamlessly. In what is good news for photography enthusiasts, not only can videos now be shared on iCloud Photo Sharing, others can put up pictures on one's Photo Stream too. In fact, sharing photos is easy, for all one needs it to do is tap a picture of a friend and share images via AirDrop.
6.Notifications : Notifications have also been revamped on the new platform. 'Today' view of notifications consolidates all the updates from calendar, stocks and other apps at one place. And best of all, the list of notifications is accessible from the lock screen.
7.iOS in the Car : With around 95 percent of car companies in the US now compatible with iOS devices, this feature puts the iOS UI on the car’s HUD. One can call/receive calls, search for directions, listen to music and more.
8.App Store : The App store now recommends apps to users based on age and their current location. But the biggest change of all that will come as a relief to many is automatic updating of the apps. Now apps will automatically update apps in the background without waiting for users to manually go to the App Store and update them.
9.Music and iTunes Radio : Apple's Music app has also been revamped on iOS 7; viewing music, tv shows and movies is just a tap away. The biggest introduction on the app is iTunes Radio, Apple's built-in music streaming service. Users can swipe through featured station on the app and simply tap on one to start playing music.
10.Activation Lock : If the phone is stolen and a thief tries to turn off the ‘Find My iPhone’ app, or tries to wipe the phone data, he won’t be able to activate the device without your iCloud password.
In addition to the above, the Mail, Calendar, Weather and Messaging apps too have been given tweaks with a refreshed UI and new animations in the case of the Weather app.
The iOS 7 will be released to the masses later this year and will be compatible with iPhone 4 and later, iPad 2 and later, iPad mini and the 5th generation iPod Touch.
