LONDON—Imagine watching frantic shopkeepers busily extinguish the Great Fire of London, or sheltering from Nazi bombing raids during the Blitz.
Now, thanks to a new virtual reality app, you can travel back in time to be immersed in these events.
The Timelooper app allows users to experience key moments in London history with just a smartphone and a cardboard headset.
