Digital technology has made a substantial contribution to the development of daily life abilities in Autistic children. Children learn a range of abilities depending on what they see, with information received through the sense of sight being recorded, explained, analysed, and merged to form a complete picture of what we're trying to learn. Many of these Autistic children, on the other hand, rely on their parents or guardians to carry out their everyday activities. Pictures are ineffectual as videos since most of the existing educational content for autistic children is in the form of visuals. The objective of this study is to provide information about the development and usability testing of a mobile app for autistic children. AutiVid is a video modelling application for teaching daily living skills to autistic children using a mobile application, as described in this study. AutiVid was created with Figma. Three teachers and three autistic children participated in usability testing of the app. The findings may also motivate educators to investigate and evaluate the possibility of combining video modelling into the design of daily living activities, as well as to develop mobile apps to address the complex needs of autistic children's teaching and learning.
