There's an app for saying 'I told you so'

If you're the sort of person who relishes bellowing "I told you so!" into other people's faces then, congratulations, you're an asshole. You're also the prime target for an app called IKI (I Knew It) that aims to take the lowest form of douchebaggery into the 21st century. Essentially, IKI is a digital, gamified record of things that you knew, or could guess, were likely to happen at some point in the future. If your prediction comes true, you'll earn points that'll keep you smugly warm while your former friends go hang out together.

Open the app and you'll be presented with a Tinder-like swiping mechanism and 20 seconds to make a snap decision. A right swipe means that you agree with someone else's prediction, while a left one adds the inverse to your record. The first option I saw was to decide if Donald Trump's square on the Hollywood walk of fame will be stolen, followed by a question about Lady Gaga's piano. Then I was asked to decide if manufacturing firm Alcoa will hit its financial targets this quarter, since that's what all hip millennials are into.

You can add your own, too, and the app will even help you pull a picture from Google if you don't have any to hand. All you have to do is add a comment that's up to 140 characters and, once approved, others can swipe in judgment to see if they agree with you. We're not sure if the app will have a human constantly monitoring each guess to dole out points when they're proved right, but it seems likely. If any of that sounds like something you want to do then you can grab the iOS version right now -- with an Android edition planned for later in the year.
