Cross-platform development allows developers to write one set of code that works on both iOS and Android, resulting in faster development time, easier maintenance and updates, and a consistent user experience across all devices.
The most powerful cross-platform frameworks are Flutter (Google), React Native (Meta/Facebook), and Xamarin (Microsoft), providing high-performance apps without compromising on quality.
Cross-platform development offers advantages such as faster time-to-market, lower development costs, easier maintenance and updates, and wider audience reach from day one.
For struggling app performance, analyze and optimize the code, and consider upgrading to more efficient frameworks like React Native or Flutter.
