The proliferation of mobile devices and smartphones, together with their built-in sensors and the ability to easily connect to other peripherals using Bluetooth, is enabling new and promising signal processing appli- cations. However, the development of mobile applications that use these features is still in the early days, requiring advanced development skills. In our work, we propose a generic framework for rapid prototyping in a mobile environment. The proposed framework enables real-time data acquisition, processing, recording, communication and visualization. As proof of concept we present an application used for electrocardiographic (ECG) signals monitoring.
