Mobile Cross-Platform Development

Build once. Deploy everywhere.

What we do

With our cross-platform development services, you can build apps with native user interfaces that share code across multiple platforms including Android, iOS, Windows, and desktop. Cross-platform development saves time and is cheaper than the development of applications using native tools. As a mobile app development company, we create highly flexible, modern, and user-friendly cross-platform solutions both cost-effectively and within the deadline.

What's included?

Integra Sources specializes in building cross-platform applications using C++, C#, and web technologies such as HTML, CSS, JavaScript, and Angular. We have proven experience working with Qt, Xamarin, Apache Cordova, PhoneGap, and Ionic platforms. We will help you choose the right tool and build a cross-platform solution that achieves the same hardware-based performance acceleration as native apps.

React Native development

React Native is one of the best and most popular frameworks for building cross-platform applications. It uses JavaScript and React, a web framework backed by Facebook. Mobile apps built using React Native are very close to native apps in terms of performance and user experience. Because React Native allows for building native modules, we use Objective C and Java for building complex functionality like video processing if a cross-platform app needs it.

Qt for application development

We use the Qt cross-platform software development framework for building applications for desktop and mobile devices, as well as embedded systems. Windows, OS X, Linux, Android, iOS, QNX, BlackBerry – apps created with Qt run everywhere. With C++ that Qt is based on we have a great possibility to work with numerous existing libraries.

Xamarin app development

Xamarin is a sound solution for creating high-performing iOS, Android, Windows Phone and macOS apps with a native look and feel. Xamarin uses C# and it's a superior option for cross-platform app development than hybrid frameworks like Cordova. Xamarin-based apps offer better performance, user experience, and functionality.

App development with Apache Cordova / PhoneGap / Ionic

All these frameworks are hybrid solutions based on web technologies such as HTML, CSS, JavaScript, and Angular (Ionic). They serve to build simple apps very fast. Applications built on Cordova offer lower performance and responsiveness than apps built on Xamarin. But the web-based hybrid solutions can be a good choice for MVP development.


While cross-platform app development is faster than native, testing is not. Even if you only code once, you have to test everywhere. We provide mobile app testing services using real devices to ensure that your cross-platform application operates correctly on all mobile platforms.

We've worked with more than 40 companies and individuals in healthcare, education, consumer electronics, and other industries

Frequently Asked Questions

Read this information to better understand the process of cross-platform mobile app development.

What is the difference between сross-platform and native app development?

In native app development, we use technologies that are native to a given mobile platform. This means a mobile app built for iPhone has the ability to use device-specific hardware and software that is installed on iPhones. Native iOS apps are coded in Swift and Objective-C, and native Android apps are programmed in Java or Kotlin.

In cross-platform app development, we use technologies that make it possible to build one code base that can run on both platforms. There are many tools for cross-platform app development. The main difference between them is the language stack. Xamarin, for example, is a Microsoft-supported framework that uses C#. React Native uses JavaScript and React, while Ionic uses HTML5 and AngularJS.

How can I choose between cross-platform and native tools?

This depends entirely on the type of app and its functionality. Native applications provide better performance and user experience than cross-platform apps. Apache Cordova, PhoneGap, and Ionic are used for building the simplest apps where performance and user experience aren't critical. Xamarin or Qt are best to use when you have a desktop app written in C# or C++ and need to extend it to mobile.

We would recommend using native tools. But if you need to support many platforms, it might make sense to build a cross-platform application.

How much does cross-platform save me?

The cross-platform app development process is roughly 1,5 times faster. But this is not a one-size-fits-all rule.

What is Qt for?

Qt is an older framework that was developed before other cross-platform tools. It's used for building multi-platform apps that run on all major desktop, mobile, and embedded platforms.

Can I use Qt for mobile app development?

Yes, you can use Qt for writing multi-platform mobile applications. These applications will be written in C++ and QML (Qt Modeling Language).

What is Xamarin for?

Xamarin is a platform for creating multi-platform applications for Android, iOS, and Windows mobile phones and also for Windows and macOS. It uses C# and is supported by Microsoft.
