The sportscaster said that UK traffic to its mobile properties, including multi-sports site ESPN UK, cricket-focused ESPNcricinfo and football site ESPN FC, had grown by 53% over the last two years.
ESPN said it planned to roll out more international versions of the app by the end of this year.
The app, which is available for iOS and Android phones and tablets, is said by ESPN to be the most downloaded sports app ever in the US, where it is already available.
It allows users to personalise relevant scores, news, updates and videos, as well as to receive custom tailored notifications and alerts.
Charly Classen, General Manager, ESPN – Europe, Middle East and Africa, said: “Mobility is central to the sports fan experience today, and is central to the way we think about serving those fans. The ESPN app is the latest chapter in our pioneering digital story, which has seen us at the forefront of online trends for more than 20 years. ESPN is synonymous with sport throughout the world, and with this new edition of the app, UK fans will benefit from a global operation dedicated to producing the very best local and international sports content personalised to their unique sports preferences.”
