The 38-year-old actress - who has daughter Apple, six, and four-year-old son Moses with husband Chris Martin - says one of her most used iPad applications is a game called `Plants Vs Zombies`, which she admits she doesn`t only have for the enjoyment of her children.
She said: "I play it almost as much as my kids.
"You choose from an arsenal of plants and battle against zombies with anything from pumpkins to mushrooms."
The `Iron Man` star also admitted she loves to use her communications device as a way of creating art, thanks to a programme called Brushes.
She explained: "Create art anywhere with Brushes for the iPad. This app has been used to create four different New Yorker covers and an entire series by David Hockney."
