Cross-platform development is on the rise, and you may wonder why. As might be assumed by the name, it allows running apps on multiple platforms – whether it is iOS or Android – and helps businesses to reach more customers, therefore, earning more money. It is no wonder that the focus is gradually but steadily shifting to cross-platform development, and new technologies emerge more and more frequently.
After being around for a while, this type of development has established two winners: React Native and Flutter. So why do we want to tell you about Flutter vs Kotlin instead of Flutter vs React Native? What is Kotlin, and can it actually pose a threat to Flutter’s popularity? What is Kotlin Multiplatform, and what are the benefits of both technologies? Let’s find out.
The number of smartphone users has been growing over the past years, covering half the population of the world in 2021 – 3.8 billion people. Where there’s demand, there will always be a need for supply to meet it, hence the mobile app revenues have skyrocketed in the recent years. It has gone from $97.7 billion in 2014 to an impressive $365 billion in 2018. Statista predicts continuous stable growth with $935.2 billion in 2023.
The numbers show the significance of mobile development. But why should you consider creating cross-platform apps? According to StatCounter Global Stats, as of January 2021, Android is dominating the market with a 71.93% share whereas iOS comes second with 27.47%. By building cross-platform apps, businesses cover two markets at the same time, thus, expand their target audience and end up reaching roughly 99.4% of smartphone users. Companies also save money from doing only half the work for the development process and the post-release maintenance.
No wonder specialists predict a further rise of cross-platform development and point out their multiple benefits. Developers and IT business owners name a few technologies that will become essential for the future development market, including Flutter vs Kotlin vs React Native.
But when should you consider building across platforms?
But when should you think twice before choosing to build a cross-platform app?
Why is cross-platform development becoming more relevant? What are the main benefits of this approach?
Earlier, people believed that iOS users are more willing to spend money on extra features than Android owners, and based their marketing decisions on this. Maybe this belief had a little of the truth, but now the situation looks different. It is clear that platform choice is mostly taste-induced and has less to do with social status. Deciding which market to choose is even more difficult, therefore, building cross-platform and targeting 99.4% of mobile users is the way to go.
Although you will still require some insights from developers about specifics of iOS and Android, especially UI, guidelines, and store publications, the united codebase significantly accelerates the development process.
Even though it is recommended to hire platform-specific developers who know the intricacies of iOS and Android regulations and standards, the majority of your team can consist of cross-platform coders. Reducing the number of workers will save a substantial sum of money and enable smoother and easier communication.
Not only will you reduce the duration of development by focusing on producing one piece of code, but you’ll also benefit from its reusability. Cross-platform development implies applying reusable chunks of code instead of writing new code from scratch. This accelerates the development process itself and also shortens the testing phase.
By requiring a single source code, cross-platform applications integrate easier with the cloud. Cloud-based technology is definitely the future of software development as it increases accessibility thus improves the user experience significantly.

On the other hand, if you write an Android app with React Native, you will need to hire a native app developer, at least as a part-time contractor. Although the React community has been growing and offering more open-source libraries to add native features, the integration of complex functions still requires input from native app programmers.
Originally based on the Mono project and acquired by Microsoft in 2016, Xamarin Forms has become one of the most well-known open-source frameworks for app development. It allows you to create reusable code and apply it across different platforms ensuring great performance and user experience. Xamarin Forms has the following advantages:
The main downside of this framework is its inability to offer complicated graphics and lightweight applications. On top of that, Xamarin Forms is losing its support and community, which makes it a poor choice for the future of app development.

What is Kotlin for Android development? What is the difference between the Kotlin programming language and Kotlin Multiplatform? Do Kotlin Android applications show better performance? You will find out in the next section of the article.
Kotlin is an open-source, statically typed programming language designed to interoperate with Java. As a standalone language, it provides excellent features over Java, but it also works well in conjunction with the older language. Kotlin’s multiplatform capabilities allow developers to share code, logic, and data across several platforms: IOS, Android, Web, and more.
In React Native vs Kotlin, the latter has much higher compatibility with the native Android platform and ensures better performance. In the Kotlin vs Dart match, Kotlin would be a better choice for Android developers since they don’t have to acquire new knowledge. However, if your team consists of iOS developers, the Dart vs Kotlin battle loses its advantage, as they will have to learn a new language either way. Let’s discuss this mobile coding language, Kotlin performance, and other benefits in our Kotlin review.
In this part, we will talk about the benefits of using Kotlin and compare Flutter vs Kotlin.
What about Kotlin’s disadvantages? Do they override the benefits? Let’s take a look at the most common limitations when it comes to developing with Kotlin.
But what is Kotlin Multiplatform? It is a software development kit prepared by the team of Google cross-platform mobile development. Kotlin Multiplatform is a new experimental feature that allows for building an iOS application as well as writing an Android app.
Android Kotlin based applications have been around for a while, as we will show you the best advantages in the next part, but now you have a chance of also deploying to the iOS platform without hiring extra workers who can work with Swift, Flutter, or React Native.
Does Kotlin Multiplatform open new doors for cross-platform development? What advantages does it have and will it make the process of code writing easier?
Kotlin has been utilized by many big players like Tinder or Trello. But why did these companies choose Kotlin, and how did it affect the result?
