In response to the critical healthcare challenge posed by pneumonia, especially among vulnerable populations, we have developed a user-friendly Android-based application aimed at early pneumonia detection. Pneumonia, caused by various pathogens, disproportionately affects infants, the elderly, and individuals with weakened immune systems. Our innovative application serves as a valuable tool for both physicians and patients, facilitating the early assessment of pneumonia based on specific signs and symptoms. Leveraging inputs such as fever, cough, fatigue, chest pain, and difficulty breathing, our system generates a pneumonia severity level, categorized as high, medium, or low. This assessment is derived from a set of thirty-two rules, expressed as IF-THEN statements, meticulously crafted in alignment with medical expertise. Our application, featuring five multiple-choice questions, delivers actionable results, contributing to the early detection and management of pneumonia.
