This is George.
George is a house cat but when it’s nice he likes to spend time in outside in the yard. Since five people live in the house and there are several ways George can be let out into the yard, the question “Is George in or out!” is frequently shouted between floors, especially when it’s getting dark or the weather changes for the worse.
Where’s George is an iOS/Android app.
When someone in the house lets George out they slide the slider from left to right, from the Home icon to the World icon. Everyone who has the app and is connected to George’s social network is instantly notified of his status. When someone lets George in they slide the slider in the opposite direction and everybody instantly knows “Where’s George.”
