Based on Statista, about one-third of mobile developers prefer cross-platform app development frameworks to build mobile applications. The growing popularity of cross-platform mobile app development services shows a major shift in how apps are created compared to the early days of mobile software.

In the US alone, there are currently thousands of companies offering cross-platform app development services. Many of these firms provide both cross-platform and native mobile app development services, frequently assisting companies in choosing between the two depending on their requirements. In this blog, we will look at the top 10 cross-platform app development companies in the USA.

What is cross-platform app development?

Cross-platform app development means building a software application that has the ability to run on various operating systems by using a single code. It is the easiest method as the developer has to write the code only once and the app starts to run on multiple platforms in the same manner.

On the other hand, native app development requires that programmers use distinct programming languages to create various versions of an application for every platform. For instance, Kotlin is usually used for Android, and Swift is usually used for iOS.

Several cross-platform app development frameworks support multiple platforms, each relying on specific tools and programming languages, including:

• Flutter — Dart
• React Native — JavaScript
• Xamarin — C#, .NET
• Ionic — HTML, CSS, JavaScript

Cross-platform development is most commonly used for mobile applications. Frameworks like Flutter, Xamarin, and React Native were originally designed specifically for cross-platform mobile app development.
