Przyjazne Słowa is a two-part educational app designed to help children with autism spectrum disorders (ASD) improve their language comprehension skills. Developed by Projekt AutyzmPG, this free app follows the principles of behavioral therapy. The app consists of two parts - Przyjazne Słowa, which is intended for the child, and Przyjazne Słowa Ustawienia, which is for the therapist to configure the learning process according to the child's individual needs and deficits.

In Przyjazne Słowa, the game involves identifying which of the presented graphic images represents the word indicated by the command. The command is available in written and audio form, and the reading of the command can be repeated. After the child selects the correct answer, reinforcement follows. Reinforcement involves presenting the correct answer again to reinforce the word and create correct associations between the word and its representation for the child. In the case of too long waiting time for the correct answer, the game gives the child a hint to encourage them to choose the correct option. The same happens if the child selects the wrong answer.
