New York, Oct 1 (IANS): In a bid to solve cases of date rape and sexual assault on campus, here comes an app that makes consensual sex as easy as a flick of your finger.

"Good2Go" is a free "consent" mobile phone app for both iPhone and Android devices that "targets college-age adults".

According to its developer Lee Ann Allman, she created the app after talking with her college-aged kids about sexual assault on campuses in the US.

She hopes it will "help alleviate the culture of confusion, fear and abuse on campus".

This is how it works:

Answer a few questions before you plan to have sex.

The opposite sex will be asked, "Are we Good2Go?"

Three possible answers: "No, thanks," "Yes, but we need to talk," or "I'm Good2Go."

"No, thanks" means there is no consent, so there is no sex.

"Yes, but we need to talk" means they have some questions they want to ask, and "I'm Good2Go" means it is a go ahead, the Slate magazine reported.

If "Pretty Wasted" is selected, the answer to "Are we Good2Go?" automatically switches to "No thanks."

The app maintains that you can't consent if you are "Pretty Wasted."
