According to Statista, one-third of mobile developers use cross platform app development frameworks for creating mobile applications. The rise in popularity of cross-platform mobile app development reflects a significant change in how mobile applications are built since their early days. 

Today, there are thousands of cross-platform app development service providers in the United States alone. Many of them offer both native and cross platform mobile app development services. 

In this article, we’ll list the top five cross-platform app development companies in the USA. It will also address common questions like what cross-platform app development is, the differences between native and cross-platform apps, and why cross-platform app development is the future. 

What is cross platform app development? 

Cross-platform app development creates software applications that can run on multiple operating systems using a single codebase. It means developers just have to write their code in one programming language and it can run on any platform, such as Android, iOS, web, or desktop.  

The opposite of cross-platform development is native app development, where developers have to write separate code for each platform in their respective languages, like Swift for iOS and Kotlin for Android.  

There are several cross-platform app development frameworks that support different platforms. Each of the platforms uses a specific programming language and tools to create cross-platform apps, such as: 

Framework	Language
Flutter	Dart
React Native	JavaScript
Xamarin	C#, .NET
Ionic	HTML, CSS, JavaScript

Cross-platform development is mainly used for creating mobile applications. Flutter, Xamarin, and React Native were initially built for cross-platform mobile app development.  

However, that is not to say cross-platform app development for web and desktop is uncommon or not important.

What are the main differences between native and cross-platform app development? 

Every developer and company has to choose between native and cross-platform app development for their app. Both approaches are suited for different needs and requirements. 

Here is a brief comparison to show their differences. 

1. Codebase 

Codebase is the most fundamental difference between the two approaches. Native development requires creating a separate codebase for each operating system, which means double the effort in terms of development, debugging, and maintenance of the app. 

In contrast, cross-platform app development allows developers to write a single codebase that runs on multiple platforms. It does that by abstracting platform-specific code and sharing components that render native-like behaviour. 

2. Performance 

Because native apps are built specifically for a given platform, they utilize the device’s hardware and OS-level features to the fullest. This makes them high-performing with faster load times and better handling of graphics and other assets. 

Cross-platform applications also offer near-native performance in most cases. Modern frameworks like Flutter are especially ahead in this regard. However, certain complexities and platform-specific challenges can hinder the performance of cross-platform apps.  

3. Development time and cost 

Cross-platform application development is significantly faster and cheaper. A single development team can target multiple platforms at once, which reduces time to market and overall project cost. Maintenance is also easier, as updates can be pushed to all platforms simultaneously. 

On the other hand, native development is more resource-intensive. Since you’re managing multiple codebases, you need specialized teams or developers proficient in each platform’s tools and languages. This leads to higher costs and longer release cycles.  

4. Flexibility and platform integration 

Native apps have direct access to all platform-specific APIs, which makes them suited for projects that require deep integrations with device features, such as: 

• Camera tools 
• Biometric authentication 
• Bluetooth 

Cross-platform frameworks rely on prebuilt plugins or third-party libraries to bridge the gap with native APIs. This approach covers only common use cases, and developers have to create plugins themselves for specific functionality features.  

5. User experience 

In user experience, both native and cross-platform apps are quite equal. Native development excels in delivering pixel-perfect user interfaces tailored to platform-specific design guidelines.  

Cross-platform frameworks like Flutter replicate this design consistency through customizable widgets that mimic native UI components. 

Why is cross-platform app development the future? 

Cross-platform app development is the logical choice to meet the growing demand for fast, scalable mobile solutions. It helps businesses reduce costs while delivering a consistent user experience across devices. 

Cross-platform apps are faster to build, easier to maintain, and more cost-effective than traditional native apps. The future of this domain is promising, especially with these innovations on the horizon: 

• AI-powered mobile app development 
• Low/code and no/code platforms 
• IoT integration 
• AR/VR support 

These technologies will power the next wave of cross-platform app development frameworks. Major players like Google, Facebook, and Tesla are already on board, signalling that this trend will determine the future of mobile app development.

Cross-platform app development has proven its value where it counts. It offers speed, consistency, and cost efficiency, which helps businesses deliver faster and reach wider audiences with half the effort required in native app development.
