But before we deep dive into the list, let’s understand some basics.

What is Cross-Platform App Development?

Cross-platform app development is an approach that allows you to create apps for multiple platforms, such as Android, iOS, Windows and macOS, using a single codebase.

The approach eliminates the need to write code for each operating system, saving you time and accelerating the development process. The ultimate goal of cross-platform app development is to achieve multi-platform reach in a cost-efficient manner.

Native vs. Cross-Platform App Development

Native apps are designed for a particular operating system using platform-specific programming languages. For example, Java or Kotlin is used to develop native apps for Android and Swift or Objective-C is used to build native apps for iOS.

As mentioned above also, a cross-platform app development approach enables using a single codebase to build apps for both Android and iOS, reducing development costs and time significantly.

For your next mobile app development project, our below comparison can help you decide which approach is right for you.
