Development and Evaluation of A Game-Based Mobile App for Increasing Physical Activity in Autistic Adults

Participants will receive visualized instructions about the PW use (e.g., search and download the app on App Store, navigate and understand key features, play puzzle games, and track step counts). During the 6-week intervention period, participants will receive reminders on wearing the accelerometer, using the app for potential incentives, and engaging in regular physical activities for health promotion.
