This paper reports the results of a short survey aimed at examining the extent to which children use mobile phone application stores. Aspects investigated included whether children used application stores on their own or parents’ devices, how children use application stores and whether they think app stores could be improved. The key contribution of this paper is the provision of evidence that children are prolific users of smart phone application stores, children are using both their parents phones and their own phones to access app stores and over half the children who download games do so at a rate of 1–2 per week. The paper also looks at how children choose the games they do on the app store and their view on how easy it is to find their chosen game. Over half the children who download games do so either having played the game before or on the recommendation of a friend. The findings raise issues about the design of app store interfaces / information architectures and whether or not children should be considered in the design of future app store interfaces.
