Guarana Antartica, the most famous guarana-based drink in Brazil, has created a social app that allows users to help friends who are struggling to get over ex-lovers. (Thanks Charlotte, Singapore).

Users can suggest the app to their friends which, once downloaded, will inform both parties if an ex-lover is trying to get in contact. The helpful friend can then offer their support, and if their newly single friend refuses it and still contacts their ex, a post showing their weakness will appear on their Facebook wall. A harsh yet undeniably effective strategy!
