There’s only a couple of weeks to go before the spookiest night of the year. That means you haven’t got long to carve a pumpkin, make a ghost costume from an old sheet… and of course load your smartphone full of scary apps and games.
Here are five of our favourite Halloween-appropriate Android and iPhone apps that we'll be frightening ourselves with this year.
1. Flappy Crush
Flappy Crush is nice and grim for Halloween, but pretty therapeutic all year round too. It's essentially Flappy Bird, only you don't play as the bird - you're the pipe. Little feathery birds flutter out on the left, and it's your job to tap the screen and crush them in the pipe before any of them can pass through to the other side. There's pixelated blood galore with a charming pile of bird bones and guts slowly building up as you play, just to make you feel extra evil.
2. Five Nights at Freddy's
It's been called the world's scariest mobile game, and it's easy to see why. In Five Nights at Freddy's you're a new security guard working the night shift at a pizzeria, and you need to keep your eye on the security cameras to look out for the animatronic animals that roam the restaurant in the dark. With a creepy soundscape and monsters that look like Furbies, it's pretty terrifying. It's also got jumpscares, so it's probably best avoided if you have a weak heart or more refined taste in horror.
3. ZombieBooth 2
Ever wondered what you, your friends, and even your dog would look like if you were zombies? Well, good news: ZombieBooth will show you exactly that. Take a photo of a face, and the app will add gore and dead eyes - and even animate it so you can watch your zombie self snarl and gnash its teeth. Photo apps for altering selfies are ten-a-penny, but the creepily authentic animations on this one make it an excellent Halloween download.
4. Year Walk
There are plenty of horror-themed adventure games on the market too, but Year Walk, from Swedish developer Simogo, is a little different. It's a haunting puzzle game that tells the tale of the protagonist's 'year walk' - a form of divination that means trekking out into the snowy wilderness and hoping to foresee the future. Unsettling and atmospheric with a gorgeous art style, Year Walk is made to be played in one sitting, preferably alone in the dark on All Hallow's eve.
5. Zombies, Run!
Here's a great way to burn off all those trick-or-treating chocolates and pumpkin spice lattes. Zombies, Run! is an exercise app that makes a run, jog, or walk that little bit more hair-raising. You're the hero of a zombie story, on the run from the undead and trying to survive. Plug in your headphones while you run and the app will play a mix of your own jogging music and live broadcasts from the zombie apocalypse.
It'll tell you when you're being chased (so you can pick up the pace), where you've found items like medicine and fuel, and what's happening elsewhere in the world. The story is supposedly so immersive, in fact, that you'll find yourself wanting to get exercising to find out what happens next.
