Sometimes we just don’t want to hit the town on a Friday night, cover that shift for our annoying coworker, or talk to that one person who’s been on our nerves for a week. Luckily, texts can be ignored and excuses can be made to get you out of nearly anything.”I’m sorry, I just saw your text!” “I left my phone in my bag and totally didn’t hear it vibrating!” “It died right after you texted me, I had no way to respond!”

We’re all guilty. But what happens if you run into that person on your morning Dunkin’ run? It’s much harder to say “no” to someone in person. Plus, it nearly always seems to be the case that the one person you were strategically avoiding is the guy or gal you end up sitting next to on the T for your 45 minute commute.

Luckily, there’s now an app that allows you to avoid these sticky situations. Cloak, the self proclaimed “anti-social network,” lets users see exactly where all their social media friends are at any given time. Using the geolocation data of your friends’ Instagram and Foursquare accounts, you’ll get a map right on your phone showing you where all of your friends – and frenemies – are hanging out in relation to where you are.

Created by programmer Brian Moore and former Buzzfeed creative director Chris Baker, Cloak joins the duos’ other anti-social apps like Rather, a plugin that replaces things a user doesn’t want to see on Twitter and Facebook with cats and, an extension that swaps baby pictures in your Facebook news feed with cats, according to CBS News.

Of course, you (hopefully) don’t want to avoid all of your friends, so Cloak allows you to “flag” specific friends as the most undesirable to see and sends alerts right to your phone. This way you can presumably never see this person again as long as you live.

There is one catch, however. The person you want to avoid needs to be an avid social media user, and they specifically need to use Instagram and Foursquare. The geolocation features currently don’t pull information from other bigger social media sites like Facebook and Twitter, which could pose a problem if your sworn enemy doesn’t check into his or her location often. But fortunately for us Bostonians, there’s a good chance that many of your friends will be tagging their Instagrammed selfies. 

Awkward street encounters are officially a thing of the past, Boston. Hurrah!
