A native app is an app that is developed for one particular operating system (e.g., iOS or Android) only. Native apps are usually downloadable via app stores like the Apple App Store or Google Play Store.
Native apps (compared to web apps) can take full advantage of the device's features like camera, vibration and GPS.
A hybrid app is one that can be downloaded and installed on multiple mobile platforms like Android and iOS.
It's built in a way that allows developers to use the same code for all operating systems.
Cross-platform apps are designed to function across multiple mobile operating systems, using a single codebase.
This approach differs from native app development, where apps are created specifically for one platform, such as iOS or Android.
A gaming engine is a software development environment, also referred to as a “game architecture” or “game framework,” with settings and configurations that optimize and simplify the development of video games across a variety of programming languages.
