Notifying the User

Applications can use notifications to greatly improve the user’s experience. For example:

• An email application might notify a user when new messages arrive. A news reader application might notify a user when there are new articles to read.

• A game might notify a user when a friend has signed in, or sent an invitation to play, or beat a high score.

• A weather application might notify a user of special weather alerts.

• A stock market application might notify the user when certain stock price targets are met. (Sell now! Before it’s too late!)
