This app is intended for entertainment purposes only and does not provide true personality predictor functionality. The user enters the profile of a male person of interest, and ScienceSays matches the profile with published scientific research statistics to predict answers to the questions user has. The profile of a person consists of facial width, finger ratio, and voice tone. The user enters it by interacting with the app. It should be noted that the answers are statistics based, and therefore, the answer should be interpreted as the likely answer, and not an absolute one.
