Bring a little bit intelligence to your iPhone

Sometimes you might want people around (e.g. in the library) to keep quiet. But it’s not always good to let others know you are the one who shushed them.

This iPhone App - Keep Quiet... is built to handle such situation for you.

Keep Quiet... continuously “listens” to the environment sound level. When the sound level reaches a “noise limit” for about a couple of seconds, Keep Quiet... will make the sound “Shhh......” automatically to remind people around to keep quiet!
