A Comparative Heuristic Assessment Of Muslim Pro And Sajda: Evaluating User-Centered Islamic Mobile Applications

<jats:p>In recent years, Islamic mobile applications have become essential digital tools for Muslims seeking to fulfil religious obligations through convenient, technology-assisted means. Applications such as Muslim Pro and Sajda provide features including prayer time notifications, Quranic recitations, and Qibla direction, enabling users to integrate their spiritual practices into daily routines. However, despite their popularity, these applications vary significantly in terms of usability, design coherence, and user accessibility, issues which may hinder user engagement and satisfaction, particularly among non-technical or culturally diverse users. Addressing this gap, the present study offers a comparative usability evaluation of Muslim Pro and Sajda using Nielsen’s heuristic framework. Employing expert review and thematic analysis, the study reveals that Muslim Pro, though rich in features and visually appealing, suffers from intrusive advertisements, complex navigation, and feature restrictions for non-premium users. Conversely, Sajda performs strongly in interface simplicity and user control, though limited in functionality, language support, and customization. The findings contribute to the growing field of usability evaluation in Islamic digital applications and offer practical insights for developers aiming to enhance the accessibility, efficiency, and cultural relevance of Islamic lifestyle apps.</jats:p>
