My co-founder and I created an iPhone app, "Taking a Break," that allows you to easily schedule breaks from Facebook and Twitter, and it auto replies to all your incoming communications, while you are on break.
Our App just hit the App Store moments ago: http://itunes.apple.com/us/app/taking-a-break/id438835787?ls=1&mt=8
Please give our app a spin; and if you mention us on Twitter or Facebook, that would be awesome and much appreciated. And of course all comments are welcome—we need suggestions on how to help the app to go viral.
The Problem Taking a Break solves: Currently, Facebook and Twitter users do not have a way of managing their accounts while they are away or unavailable. Users can either deactivate their Twitter and Facebook accounts or ignore incoming communications.
Taking a Break solves this problem (it introduces a new Social Networking Etiquette) by allowing a user to schedule breaks from Facebook and Twitter, and it politely sends auto replies to all incoming communications on behalf of the user, when the user is break.
