Websites like Facebook and YouTube create a mobile app version through a development process that adapts their services to the functionalities and limitations of mobile devices.
Developers use programming languages and tools specific to iOS and Android platforms, such as Swift or Kotlin, respectively.
They optimize the app’s design for smaller screens, ensure touch-friendly navigation, and sometimes reduce features to focus on core functionalities for better performance.
By leveraging the capabilities of smartphones, these apps can offer notifications, access to device cameras, and location services, which enhances user engagement.
