Cross-platform mobile app development faces many challenges including differences in programming languages, features, monetization options, and user interface paradigms across platforms. Native development for each platform offers the best integration and reach but requires the most effort. Cross-platform tools provide easier multi-platform development but with limitations in native features and user experience consistency. Choosing the right strategy depends on an app's goals, target platforms and audiences, and a developer's technical skills and resources. While cross-platform tools improve, fully native apps still have advantages for high-quality experiences.
