An app that endows your all of your devices with the ability to cooperate with each other, e.g. your mobile tells your thermostat that you are expected to be home in 29 minutes. The laptops can asks if you're hungry for dinner, asks your fridge about its contents then suggests a menu. Your watch chimes in with calories burned today, so the laptop adjusts the menu. Your car needs regular service, so your tablet price shops and gets back to you to suggest several open slots that fit your calendar.
