Is there an app to silence the phone for X hours?

[iMore Question]

When I have a meeting I generally flip the switch on side of the iPhone to silence it but I frequently forget to flip it back when the meeting is over. Do you know of an app that will silence the phone for the next X hours?

How about setting a reminder to flip the switch back to its original position. . . . This is a free option that takes up no additional space on your phone.

Can't u set "do not disturb" for a period of time?

You can set the "Do Not Disturb" for the amount of time your meeting is scheduled for.
