‘Countdown’ (Apple TV): There’s a new app in town and it’ll tell you exactly when you die. Once you’ve downloaded and entered your details in, it will not — under any circumstances — be deleted. Oh and if you try to alter plans to cheat death, you’ll die anyway. When one medical resident discovers the app and is given three days to live, she goes all-out to beat the prediction. It makes you think about what you are putting on your phone — and what repercussions that can have.
