Crush Detector is a tool designed to help the user evaluate and understand his or her feelings regarding a possible crush. It does this by asking four simple questions. These questions are answered on a scale of 0 to 10 based on how true it is. Crush Detector then analyzes that input and gives a rating of how big of a crush the user has on a scale of 0 to 10 and an explanation of what that means. While Crush Detector is designed to be useful in helping someone understand his or her feelings, it is impossible to do this very accurately. It is important to keep in mind that only the user really knows how they feel.
