SATReLO is a tool for the development of personalized applications, supporting language therapy in children with hearing disabilities. Applications consist of mini-games that replicate some therapeutic activities. These applications would motivate children to embrace therapy positively, increasing the time they would dedicate towards this therapy, especially at home; therefore, accelerating the therapeutic process. SATReLO allows the therapist to adapt the activities carried out according to the needs of each patient while keeping a record of each child's evolution over time. Preliminary tests show that children interact easily with mini-games and are enthusiastic about using them.
