Guaraná Antarctica is a Brazilian soft drink company. They’re also revolutionizing post-breakup back-slides and social media shaming with their Ex-Lover Blocker app.

Here’s how it works:

You “convince” your newly-single friend to download and install the app on their smartphone. They then designate the former lover’s number as “blocked”, and in the event of a moment of weakness, the app prevents the ex’s number from dialing and also alerts selected friends of the attempted contact in order for them to prevent further attempts. If the forlorn dump-ee still elects to deactivate the app and call the dump-er, the app announces their weakness on Facebook to invite public shaming. You know, the way all good friends do.
