War Horse app with original photos, maps and first-hand soldier accounts to bring World War I to life Remarkably, the £9.99 download also comes complete with an 80-minute performance of the stage version of War Horse, with music, transcripts and song lyrics by Mr Morpurgo and British folk musicians John Tams and Barry Coope. The app, launched ahead of Remembrance Day this year, includes more than 200 original photographs, showing troops in the trenches, on battlegrounds and in their rare moments of rest. Makers promised content "carefully curated by theme, allowing the reader to learn more about key battles, events and people." "Fascinating views on horses in war, trench life and the Western Front today are supported by related images, subtitles, video and rotational photography," they claim. Author Michael Morpurgo confessed he was "delighted" with the outcome, praising it for keeping the true spirit of his story "right at its centre." "When I wrote my story all those years ago in Devon, I never dreamed that Joey would gallop on like this," he said. First 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. The app, by Egmont Press and Touch Press, is priced at £9.99 and available from November 8.
