Psychology by Photo and Psychologists is a free Android app developed by Realme. The app uses artificial intelligence to determine a person's character traits based on their photo. According to recent scientific research, there is a correlation between facial features and personality traits, and the app's neural network has been trained to detect this correlation. In fact, it can even determine a person's level of extraversion better than the most observant humans.

The app offers a free psychological test that assesses five main character traits: Extraversion, Emotionality, Openness to New Experiences, Responsiveness, and Self-Control. The test provides a detailed report on the user's personality, which can help them better understand themselves and their behavior.
