apptastic

someone please invent this app --

when you want to turn down your phone ringer like at the movies or you have to turn it off like when you're on an airplane or when you might not answer your personal line like at work - this app will reply to emails, implement a voice mail greeting, reply to texts. you could choose generic replies or custom. you could set a timer so in case you forgot to release the app after the movie or whatever, the app would release based on the timer.

when could you have this ready?
