London - Can’t drag yourself out for that run you swore you’d do? Well how about being chased by the living dead for motivation?

An app has been released that plays the sound of zombies tearing after you while you run. Slow down and they get louder, forcing you to run faster to escape.

Their groans are set to stories by prize-winning novelist Naomi Alderman. And while you listen to them, you can play your own music, too.

The app, Zombies, Run! has already shot to the top of the app chart. Creator Adrian Hon said: “We’ve had people say they’ve already lost weight in a week.”

Zombies Run! is available on iTunes App Store. - Daily Mail
