Addressing age-specific issues related to IT usage is becoming increasingly significant. To consolidate the existing knowledge on the usage of mobile apps amongst older adults, this study synthesizes the research nature, patterns, and theoretical foundations in existing studies through a systematic literature review. Based on our investigation into the 22 identified articles, we find that previous studies on this topic focus mainly on app usage behaviors, app development and evaluation, and app usage learning and training. Prior studies are still fragmented and a more comprehensive and integrated framework is required to guide future research. Finally, we discuss the key antecedents of older adults’ app usage identified in reviewed articles and highlight seven heuristic topics with corresponding research questions for future research. Limitations of this review are also discussed
