There are three types of mobile app development: Native app development: Using Java, Kotlin, Python, Swift, Objective-C, C++, and React, native apps are designed solely for a particular mobile platform. However, they are more maintenance-intensive. Hybrid app development: Through a native app wrapper, hybrid apps can access device features and functionalities, using web technologies like HTML, CSS, and JavaScript. Cross-platform app development: Cross-platform apps are designed to work on multiple mobile platforms using a single codebase. You can write code once and deploy it across multiple platforms with React Native, Flutter, and Xamarin.
