Abstract: The mobile application landscape is rapidly evolving, with user expectations shifting towards lightweight, instant, and context-aware experiences. In iOS, Apple’s implementation of on-demand functionality enables applications to deliver specific features instantly, without requiring full installation. This concept, analogous to Android Instant Apps, is transforming user engagement, app retention, and performance optimization. This paper provides a comprehensive review of instant app-like experiences in iOS, including the technical framework, design considerations, use cases, benefits, limitations, and future directions. By analyzing current industry practices and developer strategies, this study identifies the critical factors influencing successful implementation and adoption of on-demand functionality. The findings highlight how modularization, app thinning, and intelligent caching mechanisms contribute to improved user experience while minimizing resource overhead.
