Notification Center in iOS 7 is not “new” but fairly improved, now it lets you know about new mail, missed calls, to-dos that need doing. The new feature called Today gives you a con- venient summary of all your tasks to- day.
With just a quick peek on your iDevice you’ll know about birthdays, weather, traffic and heads-up on tomorrow.
You can access Notification Center from any screen, including the Lock screen. Just swipe down.
