Abstract-The paper regards supporting behavioral therapy of autistic children with mobile applications, specifically applied for measuring the child's progress. A family of five applications is presented, that was developed as an investigation tool within the project aimed at automation of therapy progress monitoring. The applications were already tested with children with autism spectrum disorder. Hereby we analyse children' experience with the games, as a positive attitude towards the application is the key factor enabling practical application of the solutions in therapy. The study might be interesting for both researchers and practitioners applying e-technologies in autistics therapy.
