Note that the app prompts users to verify their level of intoxication. There are four options: “Sober,” “Mildly Intoxicated,” “Intoxicated But Good2Go,” or “Pretty Wasted.” If the user selects the last of these options, he or she is told by the app that consent is not possible.

Some might wonder, what’s to prevent people from lying? The creators have anticipated that issue and address it here. Their perspective is that if someone intends to lie, it’s no different from lying with or without the app. At worst, the app would simply have no effect in that case. More optimistically, the app could deter liars by setting up another hoop for them to jump through.

Lee Ann Allman, president of Sandton Technologies, created Good2Go with her husband, Mike. They were inspired to do something about sexual consent after listening to their college-aged children—and their kids’ friends—wrestle with the issues.
