Colleges and universities have long been bastions of youthful hedonism: Many students are away from home and constant adult supervision for the first time; alcohol flows freely; and the hookup culture continually is becoming more pervasive. However, that intoxicating stew of sex and drugs also has led to a rise in sexual assault charges and questions regarding whether a given sexual tryst was consensual.

Now there’s a new app designed to set the sexually active student’s mind at east. The app, called We-Consent, works this way: Users tell the app his or her name, the partner’s name and give an explicit yes to the activities in which they’re about to participate. This video record is then given a timestamp, a geocode and is locked away offline. It only can be unlocked by law enforcement, university disciplinary proceedings or subpoenas.

Still, some are skeptical that anyone actually will use the app. “It won’t work, and it’s totally unnecessary,” says John Banzhaf, a law professor at George Washington University. “You have two young kids, very drunk, hormones raging, in a room, and they’re supposed to whip out their phone and go through this exercise? I don’t think it’s going to happen.” (Fortune)
