Learning disability (LD) is a situation where a person has difficulties in receiving, processing and storing information in their brain. There are many types of learning disabilities including reading (Dyslexia), math (Dyscalculia) and writing (Dysgraphia). The utilization of mobile learning has increased in education practice for LD children. Despite an increased interest in mobile learning, it is surprising that very limited empirical research has actually been conducted on the mobile app design model for Dyscalculia children especially from the perspectives of mobile app designers and developers. The purpose of this paper is to investigate the existing mobile app model that is related to Dyscalculia children, to identify the factors that influence Dyscalculia children in learning and to propose the mobile app design model for Dyscalculia children in Malaysia called Calculic Kids. Hence, this research work starts with rigorous literature review search on the domains related to LD, Dyscalculia and existing mobile app model. Next, all the relevant literatures were consolidated and analyzed. From literature review, two existing mobile app models related to Dyscalculia children were reviewed and analyzed. This has resulted in identifying 3 factors and 19 components in Initial Calculic Model. © 2017 IEEE.
