Option to vibrate the phone

Give the phone app the option to vibrate with the app as well. This would be great as a backup for myself for a long show.. sometimes practice is 2 hrs and then the show is 2hrs. and for others who won't purchase the wearable withought trying the phone first.

Changed the title from "Give the phone app the option to vibrate with the app as well" to "App: Option to vibrate the phone"

Just want to say to everyone who is upvoting this: the vibration motor in a phone is far too weak for this to be useful. We are thinking about adding this but only to show how crappy it is and to advertise the value of our powerful vibration motors in the wearable :P
