I've been waiting on someone to invent an app that keeps up with my fast paced drunken antics and now Party Hopper comes along and saves the day. It runs in the background and saves battery life. And while I'm black out drunk I don't have to remember to "check in" with the app. I just set it and forget it... LITERALLY! If you like to party hard then you need this app in your life. I just hope they don't get a hold of this app in The Hangover 3. It'll be the shortest movie ever!
