The abandonment of animals is a recurrent problem in Brazilian society. This abandonment results in several problems to public health and very often go unnoticed by society and public policies. The Latinder mobile application was born from the Student Integration Project of the Integrated Computing Technical Course at an institution located in the interior of Santa Catarina state. The mobile application has the aim of combating pet abandonment and works like a social network with the purpose of facilitating the process of animal adoption.
