In recent years, assistive technologies have been adopted rapidly worldwide to increase quality treatments for individuals with autism spectrum disorder (ASD), including in Indonesia. However, adaption to a local context, e.g., using a local language, is needed to optimize the benefits. This study proposes an Indonesian version of an application technology called the media of visual communication for children with ASD (MIKA). The application development integrates agile scrum and user-centered design methodologies. The design and implementation are tested multiple times in the sprint reviews and usability evaluation to assure that the end product meets the standards of a therapy tool. MIKA offers a communication learning facility based on treatment and education of autistic and communication handicapped children (TEACCH) principles, a progress tracking and reporting feature, and a personalized content management tool based on user history and learning progress. ASD professionals, i.e., therapies and counselors, who participated in the sprint reviews and evaluations, acknowledged the advantages of using a tech-based therapy tool and the willingness to adopt MIKA. The MIKA project is in progress, targeting better facilitation of early childhood special education, and is now focusing on corrective maintenance and perfective improvements based on feedback from users and evaluators.
