Health applications are usually complicated and low end devices do not benefit from them. The focus of this thesis is on expandable health services platform for low end cell phones. Large number of mobile phones in the world are incapable using web or modern operating systems and pre-installed SMS application is the preferred communication medium. Moreover, SMS does not require a stable connection so text-based health information can still be available even during natural disasters. Although our platform is accessible through communication forms other than SMS. We propose a scalable platform for light weight health applications, providing novel and proactive client communication. Using cloud we assure the scalability, elasticity and reliability of the server side. Our multi-layered architecture provides separation of concerns and decoupling of communication and business logic. Furthermore, plug-ins can expand and customize functionalities.
