There are four cognitive aspects revealed aim to develop learning application (apps) for children with mentally retardation (MR), namely perception, association, memory, and motoric. However, motoric aspects is less noticed in apps which had being developed. In this study, we aim to design the interaction of the apps which accommodate motoric aspect. Apps may be used as companion tool aside with formal learning. Apps is focused on motoric aspect, while another four aspects are adopted from existing apps. In order to reach high level of usability, interaction design (IxD) is measured iteratively using double measurements, cognitive walkthrough (CW) and heuristic evaluation (HE). Both method is covering each other. This way is suitable to verify previous measurement and strengthen usability. Result of the study stated that apps can properly used by students and teacher and relevant with user research. There is no major usability problems found either in CW or HE measurement. Moreover, HE method ensures end-user’s satisfaction is good design principles also.
