Communication is an essential part of human interaction. Aphasia is an acquired speech disorder that disrupts communication, and depending on the type, it can affect reading, writing and even speech comprehension. With the help of technology, patients suffering from this condition can have an easy and reliable way to complement their therapy. Currently there are two different prototypes available in Portuguese medium, which will be used as a baseline for this project. They already include a raw im- plementation of the required functionalities, however, they will need to be re-engineered to comply with current trends of software architectures and also suit today’s mobile user experience. The objective of this project is to build an Android mobile application for patients with aphasia (the target audience would be composed mainly by elderly people), so the application developed is user-friendly, responsive, and adaptable to different screen sizes.
