Awkwardly bumping into your ex and his or her new flame could be a thing of the past as a new "anti-social" networking app promises to help users avoid unwanted confrontations.
Cloak identifies and maps the contacts in your immediate vicinity using location data from other social apps.
If they've posted photos on Instagram or checked in to places near you using Foursquare, their location will be shown on a map.
The app doesn't use data from Twitter because its founders say this is inaccurate.
If you're desperate to avoid a chance encounter with an acquaintance – say a co-worker, a scorned former lover or a debt collector – the app will even notify you when they enter a preset radius.
"Personally, I think we've seen the crest of the big social network," one of Cloak's founders Chris Baker told The Washington Post.
"Things like Twitter and Facebook are packed elevators where we're all crammed in together ... I think anti-social stuff is on the rise," said Baker, a former advertising executive at popular social news website Buzzfeed.
"You'll be seeing more and more of these types of projects."
A similar website launched last year, "Hell is other people", tracked friends on Foursquare and calculated optimal distances to avoid them.
Baker claimed, via Twitter, they started working on Cloak at the same time.
It's not the first time Baker has taken his scissors to society's thinly woven fabric.
His previous anti-social exploits include: unbaby.me, which replaces baby photos on your Facebook with pictures of cats; a website to troll the NSA; and "Hate with Friends", which determines whether you and Facebook mutually dislike each other.
In response to feedback on Twitter, Baker also tweeted a link to Henry David Thoreau's book Walden, which documents a two-year, two-month, and two-day period of self-imposed isolation in the woods.
Cloak co-founder Brian Moore has previously worked on a UNICEF app that asks people to go without their phones to trigger donations of drinking water to developing countries. He also developed datingbrian.com, a website documenting his attempts to find a date after ending a long-term relationship.
