Whether you are planning to invest in a mobile application for your startup or migrating from a physical store to a digital platform, your only concern is to get the best solution for your business.

Did you notice that there are approximately 2.8 million apps on the Google Play Store and 2.2 million apps on the Apple App Store, but only a few applications are leading the industry?

In every domain of the industry, there are a few leading names that are capturing the biggest segment of the market, for example:

  • Ecommerce apps: Amazon, Flipkart, eBay, Alibaba, and more are projected to generate market revenue of $2,411,638 million in 2020.
  • Gaming apps: Google Play games, Pokemon Go, Candy Crush Saga, and Lucky Money are the most popular iOS app categories, accounting for 25% of the active applications and with over 18.74 million monthly users in the U.S.
  • Online food delivery apps: Grubhub, Doordash, UberEats, Postmates, Instacart, and more are a few of the leading names that always come to mind first when it comes to ordering food.
  • Social media applications: Instagram, Facebook, Messenger, Whatsapp, and more
  • Entertainment apps: YouTube, Netflix, Apple Music, Spotify, Pandora Radio, Amazon Prime Video, Google Play Music, Hulu, and more are accessed by more than 570+ million users every month.

The central question is what exactly makes them successful and helps them stand alone in the market? Many of you may be eager to follow on their apps with clones, but before that, you need to identify the secret of their success.

There are multiple factors that contribute to their success, including features, complexity, UX/UI design, their back ends, their front ends, the skills of the developers, and more. But the real success lies in the technology they choose to develop the application.

No matter how brilliant an app idea you have and what unique things you have integrated into your app, if you choose to develop your app with an old, tired, and outdated programming language, then you might be putting your entire investment at risk.

And if we consider the trend of mobile applications and the growing needs of the business, then it won’t be wrong to say that entrepreneurs are nowadays more interested in cross-platform mobile applications. Since hybrid apps help in targeting users on a large scale through multiple platforms, entrepreneurs are looking forward to hiring a mobile app development company that has experience in developing them.

Again the major question comes up in front of you: Which programming language should you choose to develop an application?

When it comes to developing a hybrid application with the top cross-platform mobile app development frameworks, React Native, Flutter, and Ionic are the titans of the community.

Now the real challenge comes here when you need to choose between these three leading mobile app development frameworks. Don’t worry, we will make it easier for you by simply comparing the points of each framework to help you understand which fits best to your business needs.

Let’s begin with a short intro of each framework.

The Baseline of Open Source Cross-Platform Mobile App Development Frameworks

Overview

Flutter and React Native both are advanced software development kits, but Flutter is developed and supported by Google whereas React Native is developed by Facebook. Ionic is one of the oldest programming languages and was developed by Driffy Co.

React Native

React Native is an open source framework launched in 2015 and written in various languages, including JavaScript, Swift, Objective-C, C++, and Python. Basically, it provides all the tools and services for developing high-end cross-platform applications on iOS, Android, and Windows with the ability to offer native-type performance.

Major clients: In just a short span of time, this framework has been adopted to develop various apps, including Instagram, Facebook, Airbnb, Walmart, UberEats, and so on.

Flutter

Flutter is powered by Google and adds a powerful layer to the app development process as it helps in developing beautiful native-type apps. It provides its own rendering engine, ready-to-use widgets, command-line tools, APIs, and more that make the entire development process easier. However, when compared to React Native, it’s still growing in popularity as it was just launched in 2018.

Major clients: Despite being recently launched, Flutter is used by Google Ads, Alibaba, Reflectly, Birch Finance, and more.

Ionic

Ionic was introduced in 2013 as an open source SDK for cross-platform mobile app development. Since it uses various technologies, including HTML5, CSS, and SaaS, building cross-platform mobile applications is easier with Ionic.

Major clients: Being in the market for a long time, it has been used to build such apps Sworkit, JustWatch, MarketWatch, and more.

Now let’s move towards the major points that help you understand the pros and cons of each framework with this simple comparison.

Comparing the Major Attributes of React Native, Flutter, and Ionic

Since every business has different needs and hires a mobile app development company with different levels of skills, it’s not mandatory that a framework that fits one startup also be perfect for another startup. So here we will discuss the top attributes that developers usually look for while comparing the frameworks.

1. Programming language

Overview: React Native is based on JavaScript and Flutter uses Google’s in-house programing language, Dart, but Ionic uses multiple languages.

React Native: When it comes to choosing the framework based on the programming language, React Native might be the top preference of developers as it is based on JavaScript, which is at present one of the most popular and dynamic languages for developing hybrid apps. In addition, this framework combines all the advantages of JavaScript and React and is backed by Facebook. The thing about React Native that makes it stand apart from the other programming languages is that it provides the ability to write a few components in Swift, Objective-C, or Java when required.

Flutter: Since Flutter is a baby of Google, it uses an in-house language, Dart, that helps you develop applications for Android, iOS, and the web. Compared to JavaScript, Dart is still an uncommon language. But despite being new, the language has a great potential to take the industry by storm in the coming years.

Ionic: It uses multiple technologies (including HTML5, CSS, and JS) to develop and run applications and access the Cordova wrapper to use native platform controllers. To improve the quality of the code, you can also use TypeScript while using Ionic.

2. Execution and reusability of the code

Overview: When hiring a mobile app developer for a cross-platform application, code reusability is the biggest concern for the company. All three frameworks use different code execution strategies. React Native follows “learn once and write anywhere,” Ionic uses “one code base, any platform,” and Flutter offers you an advanced set of features to expedite the coding process.

React Native: The prime principle of writing code with React Native is clearly portrayed for you: A single code base can be used to develop multiple apps for various platforms including Android, iOS, and Windows. This will help developers to build better apps in a short time span.

Flutter: The standard reason behind the increasing popularity of Flutter is that it provides a comprehensive toolkit that helps developers create modern apps with ready-to-use widgets, APIs, and its own rendering engine. By leveraging the rich feature set of Flutter, developers can create beautiful mobile experiences.

Ionic: Its simple mantra of “one code base, any platform” provides the privilege of reusing the code base for various applications. By using the same code base, developers can build a highly interactive app in a quick time frame.

3. Popularity and Community

Overview: If you are assuming that the oldest framework has the highest popularity and community support, then you might be mistaken at this point. According to Statista, React Native is used by 42% of developers, whereas Flutter, despite being a new framework, is used by 39% of developers, and Ionic is used by 18% of developers. If we compare all these three frameworks, then React Native might be at the top position. However, it has the same percentage of developers as in 2019, and Ionic has been reduced from 28% to 18%, whereas Flutter has shown a bar rising from 30% to 39%.

React Native: While evaluating the community support of frameworks, undoubtedly React Native will easily steal the show. Since it’s based on the most essential web development language, JavaScript, and utilizes popular React libraries, the network of developers is speedily growing as compared to Flutter and Ionic. But according to Github, React Native has 89.7K stars, 3.7K watches, and 19.9K forks.

Flutter: Flutter is a recently launched framework for the community, so compared to React Native and Ionic, it has a small community. But the fact that it’s intensely advertised by Google and is rapidly increasing in popularity will soon make this framework a major thing in the mobile world. Moreover, in just a short timeframe, Flutter has achieved 99.2K stars, 13.7K forks, and is watched by 3K developers, leaving aside React Native and Ionic.

Ionic: Being one of the oldest frameworks, Ionic has often improved its framework. It has the second-highest community support and a great marketplace. In terms of popularity, it has 41.6K stars, 13.3K forks, and is watched by 1.8K developers.

4. Performance

Overview: For any business, app performance is one of the most crucial deciding factors. The performance of the app depends on various factors, including the efficiency of writing code in that particular framework. But here we will evaluate performance by simply analyzing the runtime of the app.

React Native: Since this framework uses native APIs and components, it helps you build an application that provides a native look and feel.

Ionic: Unlike other frameworks, Ionic uses advanced web technologies, like HTML, CSS, JavaScript, that help in creating high performing hybrid apps. But it requires plugins and third-party packages to wrap your application in a native cover.

Flutter: Undoubtedly React Native and Ionic both deliver excellent performance, but Flutter goes a step ahead as it provides ready-to-use plugins, a wide range of widgets, and its own rendering engine that helps in building beautiful, high-performance cross-platform applications.

5. User interface

Overview: It’s only the app design and the user interface of the app that help users determine whether they will continue using this app further or uninstall it. React Native uses the React library to organize the UI and Ionic makes use of HTML and CSS, whereas Flutter ensures the best user interface comparatively to others.

React Native: To deliver a native-like app experience, React Native utilizes React libraries that offer amazing UI.

Ionic: Ionic is totally dependant upon web technologies, like HTML and CSS, to deliver a native-type app experience, but it also accesses Cordova to gain the look and feel of native apps.

Flutter: Undoubtedly, Flutter provides the best user interface by simply skipping interactive bridges with native components, which is why a large number of mobile app development companies prefer to use Flutter for developing cross-platform apps. It’s true that Ionic can provide a cross-platform application, but as it uses Cordova for running JavaScript, it fails to beat the efficiency and performance of Flutter and React Native.

6. Current state of usage

Overview: It’s perfectly fine to get impressed with any technology, but how the real world uses that framework or thinks about it is what really matters.

React Native: Whether it's about mobile or web app development, JavaScript is the king of programming languages. It has not only maintained its position in the top five programming languages but also keeps its importance in the app development industry. React Native is based on Javascript, and this is why a couple of leading companies, including Facebook, and Airbnb, have adopted this framework for development.

However, on the other side, you can’t ignore the fact that Airbnb later switched to another technology. And because of this movement, the React Native team is working on getting rid of some of the documented limitations and problems.

Flutter: Despite being relatively new, Flutter has already set the benchmark in the development industry by simply providing a complete software development kit to developers. With Flutter, not only is it easier to build beautiful apps, but it’s also quicker to edit code with the hot reload feature.

With plenty of advanced features, Flutter has already impressed approximately 39% of developers and has been used to build some major applications, including Google’s AdWords. The way Flutter is rising in popularity and usage, it’s safe to predict that more great apps will be developed with Flutter. All you need is to hire an app developer with a solid command of this framework.

Ionic: Comparatively, Ionic is the oldest framework, but still it has not developed any groundbreaking, outstanding app. Still, 86,400 development teams have leveraged Ionic to develop Android and iOS apps.

7. Cost of app development

Overview: Whether you are a startup or an entrepreneur, app development cost is one of everyone’s major concerns. The cost of app development is directly related to how long it takes to develop the app, the cost of the developer, and the libraries used.

React Native: React Native is an open source framework and allows developers to access a wide choice of libraries for free. All you need to do to reap the maximum benefits of this framework is to hire a software development company that has a skilled team.

Flutter: Flutter is also an open source platform that allows developers to access a wide choice of widgets, libraries, and APIs for free. Moreover, you can easily find Flutter app developers with a starting price of $18 to $35+ all across the world.

Ionic: It is a free, open source cross-platform mobile app framework, but for a professional development environment, you need to go for the paid version. However, Iconic Pro can easily expedite the development process and make it easier for developers to create an application in real time.

Which Framework Will You Choose for Cross-Platform App Development?

After all these metrics and comparison, you need to first decide whether you want to stick with native languages, like Swift, Object C, C++, and Java, and want to proceed with the hassle of learning and mastering two different languages for developing two different apps. Or do you want to choose one framework that works well on multiple platforms?

Let’s assume you are ready to go with a cross-platform app development framework. How will you decide which is the best technology fit for you, even after reading this entire article?

Let’s make it simple for you.

If you’re looking for wrapped app solutions, then Ionic is the perfect solution for you. But as Ionic uses third-party components or Cordova to give a native-like feel to the app, it fails to beat the efficiency and performance of Flutter and React Native. On the other hand, Ionic ensures you a super-fast development experience and enables you to build two apps with one stack in less time.

Secondly, if performance and the need to access a wide range of native device features are priorities, then Flutter and React Native can be the ultimate choice for you.

Rest easy — everything has been explained in detail above.
