Traditional mobile app development often involves creating separate applications for iOS and Android, requiring distinct codebases, user interfaces, and databases, which can be time-consuming and resource-intensive. Cross-platform mobile app development addresses these inefficiencies by enabling the creation of a single app that is compatible with multiple platforms, typically through the use of frameworks rather than platform-specific programming languages. These frameworks, such as React Native, Flutter, and others, provide pre-built components and enable near-native performance, reducing development time and resources. Additionally, some platforms like Bubble offer a no-code approach by allowing users to visually design apps, which can then be translated into native apps using frameworks like React Native. While choosing the right framework depends on factors such as developer expertise, performance needs, and the desired level of customization, cross-platform development generally offers significant advantages in terms of speed and efficiency compared to traditional native app development.
