Joi App is a pioneering application designed to enhance emotional and behavioral health management through advanced AI technology. It utilizes a patented multimodal assessment approach that evaluates facial expressions, voice patterns, and contextual information to provide insights into emotional states, stress levels, and signs of depression. This innovative method captures data that traditional questionnaires may overlook, offering a more nuanced understanding of mental health.

The app features a three-part assessment system, including machine learning evaluations and standardized psychological tests like PHQ9 and GAD7. Users can log their mood and stress levels over time, generating detailed PDF reports for personal use or consultations with healthcare professionals. With multilingual support in Korean and English, Joi App aims to improve self-assessment convenience and enhance the overall efficiency of medical consultations.
