When it comes to developing a mobile app, one of the biggest decisions you will make is choosing the appropriate development framework. Since a framework is a set of pre-written code that developers can use to build mobile apps more efficiently, cross-platform mobile development frameworks allow devs to write code once and deploy it on multiple platforms, such as iOS and Android.

Selecting the right framework can have a significant impact on your app’s success. In this post, we’ll discuss the main factors to consider when perusing cross-platform mobile development framework to help you make the best decision for your app.

The Deciding Factors When Choosing the Right Framework

The very first step should always be the careful consideration of the specific requirements that your app will or may have. These are the following:

App Requirements

Consider the application’s functional and non-functional requirements. Functional requirements are features that the app must have to meet its objectives, while non-functional requirements are aspects such as performance, UX, and security.

Developer Expertise

Your developers’ experience with a specific framework is also crucial to consider. If your developers are not familiar with a particular framework, it can lead to development delays and increased costs.

User Experience and Performance

User experience and performance are critical features as well, since the application’s success all but depends on how your audience will perceive and use it. Users expect apps to be fast and responsive, and as such the UI/UX elements must be intuitive, convenient, and generally easy to use.

Community and Support

Choosing a framework with a robust community and active support system can actually make or break cross-platform mobile development. A strong community can help you resolve issues and provide support to developers.

Cost and Licensing

Finally, it’s essential to consider the cost of the framework and its licensing. Some frameworks are free, while others require a licensing fee or come with additional costs for advanced features.

Pros & Cons of Popular Cross-Platform Frameworks

With the basic factors now in mind, let’s examine the strengths and weaknesses of some of the most popular frameworks:

React Native

React Native is a popular framework for cross-platform mobile app development. It allows developers to use JavaScript to build apps for iOS and Android platforms.


  • Developed by Facebook, with a large community and active support
  • Fast development and testing, with live reloading feature
  • Native look and feel for both iOS and Android platforms
  • Strong performance


  • Limited support for third-party libraries
  • Can be challenging to set up and configure
  • Difficult to integrate with existing apps


Xamarin is a Microsoft-owned framework that allows developers to use C# to build apps for iOS and Android platforms.


  • Good performance as well as native look and feel
  • Allows developers to share code across platforms
  • Strong integration with Visual Studio and other Microsoft products


  • Can be expensive for enterprise use
  • Limited third-party library support
  • Depending on developer experience, it can require more time to set up and configure


Flutter is a relatively new framework for cross-platform mobile app development. It allows developers to use Dart to build apps for iOS and Android platforms.


  • Fast development and testing with hot reloading feature
  • Native look and feel for both iOS and Android platforms
  • Good performance


  • Limited third-party library support
  • Relatively new framework with a smaller community
  • Steep learning curve for developers who are not familiar with Dart


Ionic is a popular open-source framework that allows developers to use HTML, CSS, and JavaScript to build apps for iOS and Android platforms.


  • Easy to use and configure
  • Good performance with a native look and feel
  • Large community and active support


  • Performance limitations, heavy reliance on web technologies (more performance issues on older devices)
  • Restrictions or limitations on certain native features
  • Large overhead and slower load times due to many out-of-the-box components
  • Reduced flexibility and increased complexity in case of custom apps

Building and Testing Your App on Multiple Platforms

Once your code has been written and your project prepared for cross-platform development, the next step should be building and testing your app on various platforms. This step is crucial as it allows you to detect and address compatibility issues early on during development.

Xamarin is one of the go-to tools for building and testing cross-platform apps, offering C#/.NET developers an easy way to develop native apps for Android, iOS and Windows using C# or.NET programming languages. Furthermore, up to 90% of your code can be shared across multiple platforms, which reduces development costs substantially.

React Native is a highly-preferred tool, enabling developers to build native apps for iOS and Android using JavaScript and React. React Native offers fast development cycles with its live reload feature enabling real-time viewing of changes as you edit code.

Moreover, once your app is built, it is imperative that it is thoroughly tested on various devices and platforms to ensure its correct functionality. While emulators and simulators are effective at testing across platforms, real devices should also be utilized to ensure it performs as expected.

Cross-Platform Deployment and Maintenance

After building and testing your app on multiple platforms, it’s high time to deploy it to app stores and make it available to your users! Depending on the platforms you’re targeting, you may need to follow specific guidelines and requirements for app submission.

Once your app is live, it’s important to monitor its performance and fix any issues that arise. You may need to release updates to address bugs or compatibility issues with new platform releases. Of course, it’s also imperative to gather feedback from your users and make improvements based on their suggestions; such feedback loop can help you improve your application’s user experience and drive engagement.


Cross-platform mobile development can be an economical and time-saving way to create mobile applications that work on multiple platforms. By following the steps outlined above, you can ensure your app will be well-designed, compatible with different platforms, and user-friendly in general.

Overall, choosing the appropriate cross-platform mobile development framework for your project depends on several key considerations, including project requirements, development team experience and available resources. Carefully considering each framework’s strengths and weaknesses will allow you to make an informed decision that will result in creating a successful app – whether Flutter, React Native, Xamarin, Ionic, or some other platform is chosen. Just keep in mind the unique benefits and limitations for each framework when making this important decision!
