React Native is the popular cross-platform framework

Cross-platform development is the best solution for a new app because it significantly speeds up the release time and allows you to attract the owners of different devices. There are many frameworks that are suitable for both iOS and Android. We at MDM work with the popular React Native and are happy to tell you about the framework based on personal experience.

What is React Native?

React Native is a JavaScript framework that is used to develop cross-platform mobile applications, especially native and hybrid ones. This is the brainchild of Facebook, which decided that there was no need to sacrifice either the complexity or the cost of the development process. React Native was announced at the Facebook React.js Conf conference in February 2015, and a month later, the creators opened the source code.

To understand how popular this technology has become over the past time, let’s turn to the developer survey conducted by StackOverflow this year. In 2019, more than 90,000 developers shared information about their work and professional preferences. The survey results show quite interesting results. This library has become one of the most beloved and sought after frameworks, having received 62.5% of the respondents’ votes and entering the TOP-10. A pretty good argument for someone thinking of becoming a React Native developer, right? But let’s not make hasty conclusions. Instead, consider the core features of React Native that made this library so popular.

Why React Native is useful


This is the main advantage of the framework. You don’t need to develop the application separately for iOS and Android, one code is suitable for both platforms. This greatly saves money and time. Altogether, with React Native, companies can reduce development costs by up to 50% without sacrificing quality. It uses the ReactJS UI library developed by Facebook for user interfaces.

Visible results

The framework has the Live Reboot function, which allows you to view the latest code changes immediately, breaking the screen into two parts: the first shows the code and the second shows how it will look on the device’s screen.


React Native is a free, close to native open-source SDK. This allows you to use the already created code for new versions of programs and bug fixes. Open-source also provides an opportunity to help creators modify an open-source program.

User interface

React Native offers a simplified UI, which is better known as an open-source JavaScript library. In React Native, UI elements should mainly be developed from scratch, while in native Android development, the Google Design Support Library is already connected. This gives the developer freedom in terms of interactive and responsive design.


React Native also supports third-party plugins, offering native JavaScript modules and modules. For example, if you implement a map in your application, React Native simplifies your work because you can simply connect the plugin with its own or third-party module.

Easy to learn

React Native is written in JavaScript, which is pretty simple. JavaScript is one of the most widely spoken languages in the world. In the TIOBE index, at the moment, it takes 7th place (and the index is growing), and according to the results of the Stack Overflow survey, it is in the first place. Therefore, its study will be a great start for beginners in the field, because it provides ample opportunities for application.


If developers experience problems while working with React Native, they can always contact their colleagues. The community of this framework is working hard to keep the documentation up to date with comprehensive resources and API links.


Duplicate elements on pages are rendered only once. So, for example, in cards with the same photo, but with different text, the photo will be rendered only once. This allows you to reduce the loading speed of the application pages.

React Native Disadvantages

The framework is pretty young

React Native is frequently updated, and some components are still missing. Therefore, developers have to constantly monitor updates to the technology and its libraries. If you do not follow the updates, applications on React Native simply stop working.


React Native supports the iOS platform better than Android. At the time of development, Android may have problems working with React Native. Plus, iOS provides detailed documentation, unlike Android.

It is advisable to know native languages

Most of the time, developers write code for cross-platform JavaScript applications. However, there are times when you have to get into the native language for each platform. Therefore, JavaScript is indispensable in this case.

What applications can be developed with React Native

The React Native framework was used to create applications such as Instagram, Airbnb, Walmart, UberEats, Tesla, Skype, Bloomberg, Discovery VR, etc. React Native provides all the basic and best practices for developing hybrid mobile applications.

The framework is ideal for creating the next types of applications:

  • Social networks. The framework works well for implementing features such as access to the camera, fingerprint, geolocation, and maps.
  • Applications with simple animations. If you want to create a simple application in which there will be no complicated animation, we advise you to take a closer look at React Native and use this framework to develop a future project.
  • Product with minimal functionality (MVP). If you plan to test business hypotheses and you need a working MVP with cool visualization, React Native is a great choice.

Is it difficult to find a React Native developer

Since JavaScript is one of the most popular languages among developers, it will not be difficult to find a talented person for the project. This is a big advantage of React Native over other younger programming languages. The cost of the work of React Native developers is also significantly lower than, for example, those who work with Swift or Kotlin.

React Native App Cost

The cost of any application depends on the complexity of the tasks, as well as the number of resources. If the advanced functionality of the application is provided, then before release it is necessary to test it on different gadgets. Accordingly, more errors and shortcomings are revealed, which also require elimination, on which the cost of work depends.

The average developer cost for React Native is between $81 and $100 per hour, depending on location and experience. If you take the average value of $90 per hour, wages will be approximately $14,400 per month.


Although React Native has dramatically gained popularity, many developers refuse to use it. It works great for simple applications, but complex architecture projects created with React Native are slow. Many functions lag, and the popularity of this framework is declining. Therefore, it is always worth choosing technologies for development, depending on the complexity of the applications.


Concluding the discussion of the pros and cons of React Native, we would say that this is more than useful technology, known for its simplicity and time-saving. The framework allows developers to reuse codes and modules, and also provides the benefits of a large community base, hot reboot, and stable applications. We recommend evaluating the complexity of future applications before choosing tools for their implementation.
