I know there are apps that can set the ringer to mute during certain times of the day. However, I am wondering if there is an application that will allow me to tell the phone to not ring for the next hour (or any set amount of time). The problem is that periodically I will go to an unscheduled event in when I want to mute the phone, but inevitably forget to unmute later. I'd like to quickly choose to mute for an hour and then it automatically unmutes after an hour... Thanks!
