Notification Center alerts you to everything that's happening on your iPhone, iPod touch, or iPad using a combination of banners, popups, badges, and sounds/vibrations. That's great if it's something really important like an alarm, appointment, or iMessage. But when every app and game on your iPhone starts blinking, beeping, and buzzing, notifications quickly turns into interruptions. When everything is urgent, nothing is. Luckily, Notification Center also lets you turn off those banners, popups, badges, and sounds on an app-by-app basis, so you get to decide what's important enough to get your attention. That's right, serenity -- and sanity! -- can be yours again in just a few simple steps.
