The app features an 80-minute reading of the book, an interview with the author and a timeline that explores the First World War through documents, maps, photographs and film.
“When I wrote my story all those years ago in Devon, I never dreamed that Joey [the hero of the story] would gallop on like this,” said Michael.
“First there was the National Theatre’s amazing production, then a wonderful movie by one of the world’s greatest directors, and now an app which truly has the spirit of my original story right at its centre. I couldn’t be more delighted.”
Dorothy Brooke set up The Brooke hospital in Cairo, 1934, to rescue army horses and extracts of her diary and images of the horses there are included on the app.
The Brooke’s CEO Petra Ingram said: “It is a wonderful way to bring the War Horse story alive in a way that is engaging and fun.”
The app costs £9.99 and is available from www.itunes.com/appstore.
