Mobile devices (smartphones, tablets, e-readers, etc.) have come to be used as tools for mobile learning. Several studies support the integration of such technological devices with learning, particularly with language learning. In this paper, we wish to present an Android app designed for the teaching and learning of Portuguese as a foreign language. We aim to promote new experiences in the field of mobile learning, based on the concept of Social Learning (Mondahl & Razmerita, 2014).
