Abstract: This paper proposes a usability measurement forevaluating mobile applications. The measurement incorporates usability viewpoint of both, usability specialist and non-usability expert. The resulting usability measurements were validated through a survey of 113 industrial practitioners in Malaysia. Cronbach alpha of .952 reveals that the survey response is consistent and reliable. Hypothesis testing using a Chi-square goodness of fit indicates that the usability measurements were significantly feasible for real practice with p<.000.Mobile usability studies previously conceptualised usability from HCI perspective (e.g. usability attribute and heuristics), constraints and limitations of mobile devices. On the contrary, this paper characterise usability by integrating design features of mobile application through usability features, and quality attributes through usability criteria, in conceptualising apps usability dimension.
