In this app, completely free and without advertising, you will find many stories and songs in sign language that you can use at school or at home with deaf children. You can freely browse the stories and songs but, if you register as a user, you can organize your own playlist, save to favorites or add new videos.My trunk in sign language is a project developed by the CNSE Foundation, made possible thanks to the support of the Ministry of Education and Vocational Training and the ONCE Foundation.
