Just when you thought there were enough social networks to distract you from your family, friends and work, there’s a new app in town. Except this one isn’t exactly new. Vero, which was originally released in 2015, has spiked on Apple’s App Store, jumping to the top trending spot and becoming a phenomenon out of virtually nowhere.

The spike in popularity began on Feb. 22 when an influx of users from the cosplay and tattoo communities began jumping to the app. So far, the app has been downloaded more then 500,000 times, according to the Google Play Store. Numbers for iOS downloads aren’t available.

It would appear that even Vero wasn’t ready for the sudden spike in popularity. Every time I used the app I was met with some kind of server error. That’s to be expected, though, considering the number of people that are likely signing up for the service in such a short period of time. The company said it’s working to improve server stability as soon as possible.

Available for Google’s (GOOG, GOOGL) Android and Apple’s (AAPL) iOS, Vero promises to be a kind of anti-Facebook. It’s manifesto — yes, it has a manifesto — lays out the reasons for the app’s existence as a blow-by-blow repudiation of how other social media networks do business.

Unlike Facebook (FB), Twitter (TWTR) or Snapchat (SNAP), Vero doesn’t support itself via advertising. Instead, it functions as a subscription-based service. The first million users, however, can sign up for free. Vero said it will release information about its pricing and user count in the coming days, but I was able to sign up without issue, which means the app likely hasn’t hit that 1 million user threshold.

Co-founded in 2013 by Ayman Hariri, the Lebanese billionaire and son of former Lebanese Prime Minister Rafic Hariri, Vero, which is Latin for “true,” says its decision to go with a subscription-based model was driven by a desire to ensure that users are the company’s customers rather than advertisers.

The social network says this will allow it to deliver the “best social experience instead of trying to find new ways to monetize our users’ behavior or tricking them back into the app with notifications.”

Vero allows you to categorize your friends into three different categories: Close Friend, Friend and Acquaintance. Vero says this allows users to better customize which audiences see their posts. So if you don’t want your acquaintances seeing photos of you partying last weekend, you can set the privacy to Close Friends and Friends. Your connections won’t see how you categorize them.
