She added that often people ignore signals and signs because of how the person makes them feel physically.

One of the app's creators told The Daily Beast that the group came up with the idea as a way to improve traditional online dating sites like Match.com.

"It would be great, as guys, if you could find out which girls are actually into you and not dance around anything," he said.

Skip the dating and jump straight to the sex, one of the creators said.

Crockett, who has authored several book on creating lasting relationships, met her current boyfriend of three years on eHarmony.com.

She said the couple spent several weeks emailing and talking on the phone before they met in person.

Crockett said she is a firm believer in using technology to cultivate a relationship, but this app goes about it the wrong way.

"I think the app contributes to people going into a relationship and actually dating backwards," Crocket said.

"It's the exception more than the rule that a relationship will last if it has begun with a physical encounter rather than emotional spark," she added.

Currently the app only matches users of the opposite sex.

"Support for same-sex selections is already under development," the app's creators told Mashable.
