Purpose In the context of an increasingly competitive mobile app marketplace, app icons function not only as visual signifiers but also as important carriers of functional semantics. From a visual-semantic integration perspective, this research investigates how icon labels (present vs. absent) and icon styles (text-based vs. graphic-based) affect users' perceived semantic fit and download intention, and examines the moderating roles of cultural differences and app type. Design/methodology/approach Three between-subjects experiments (N = 291, 389, 836) were conducted. Study 1 employed a 2 (label) × 2 (style) design to test the core effects and a moderated mediation model with semantic fit as the mediator. Study 2 extended the model by introducing culture as a moderator using parallel experimental procedures in China and Korea. Study 3 incorporated application type as a contextual boundary condition. Data were analyzed using MANCOVA and PROCESS-based moderated mediation analyses. Findings Across studies, icon labels consistently enhanced perceived semantic fit but did not uniformly increase download intention, revealing a trade-off between semantic clarity and visual fluency. Text-based icons strengthened semantic interpretation, whereas graphic-based icons elicited higher download intention through affective appeal. Semantic fit mediated the effect of labels on download intention, with this mediation being stronger for text-based icons. Moreover, cultural and app type significantly shape these mechanisms, Chinese users show a stronger preference for labeled, semantically explicit designs, whereas Korean users favor label-free, visually minimal designs; utilitarian apps are better served by label–text combinations, while hedonic apps benefit more from graphic treatments. Originality/value These findings refine theories of visual-semantic congruency by revealing how cultural cognition and task fit moderate interface-design effects, and provide empirical guidance for cross-cultural app icon design and market localization.
