Mobile app usage is surging globally, with users dedicating four to five hours daily to apps on devices predominantly running Android or iOS, which hold 71% and 28% of the mobile OS market share, respectively. To maximize app exposure, developers traditionally needed to create separate native apps for each platform using Swift or Kotlin, increasing time, cost, and complexity. However, mobile cross-platform development frameworks offer a more efficient solution by allowing developers to create software compatible with multiple operating systems from a single codebase, thereby reducing effort and speeding up the market entry. These frameworks, such as Flutter, React Native, Xamarin, and Ionic, enable consistent user experiences across devices and are complemented by mobile databases like Couchbase, which ensure fast, reliable, and synchronized data handling, even offline. Couchbase enhances the development of cross-platform apps by providing a mobile database stack that supports fast synchronization and offline functionality, making it an ideal choice for developers aiming to deliver high-performance apps efficiently.
