A multi-platform app is a software application that is designed to run on multiple platforms or operating systems. This means that the app can be installed and used on a variety of devices, such as smartphones, tablets, and computers, running different operating systems, such as iOS, Android, and Windows.
Multi-platform apps are developed using programming languages and frameworks that are compatible with multiple operating systems. This allows the app to be distributed and installed on a wide range of devices, reaching a larger audience.
There are two main types of multi-platform apps: native apps and hybrid apps. Native apps are developed specifically for a particular operating system and are written in the programming language and framework supported by that operating system. Hybrid apps, on the other hand, are developed using cross-platform frameworks that allow the app to be built once and then deployed on multiple operating systems.
Overall, multi-platform apps offer the advantage of being able to reach a wider audience and being able to run on a variety of devices. However, they may require more development resources and may not offer the same level of performance as native apps.
