Mobile solutions for front-line health workers in developing countries

We introduce an architecture for low-cost mobile health (mHealth) applications that run on health-workers´ existing devices. Moreover, we envision extending the phone´s capabilities with an external to attach ¿sensor¿ modules, such as pulse oximeter, ECG and phonocardiogram. Our design principles are frugality and simplicity. We propose a comprehensive solution to aid health-workers in their daily tasks, at a low-cost and high penetration rate.
