House Doctor connects smartphone users with doctors directly for free. The mobile instant messaging platform aims to solve the medical information inefficiency problem, especially in Asia, by increasing medical layman’s accessibility to healthcare professionals. Users can send their healthcare-related queries privately over instant messages to Hong Kong qualified doctors across different fields and can expect to get their questions answered within a day. Medical professionals on our platform include Hong Kong qualified medical doctors (general practitioners and specialists), animal doctors (veterinarians), and mental doctors (psychiatrists and psychologists). After ending the private text messaging conversation with doctors, users will have to rate and review the doctors in order to get the next free chance to pose another question. Doctors’ ratings and profiles will be shown in a general directory where users can locate doctors of their preferences.
