Cross-platform App Development – Everything You Need to Know

Cross-platform App Development

Mobile App Development

Mobile app development for Android and iOS devices separately is expensive and time-consuming, especially if you’re a startup or small business. You’ll need specific skill sets or dedicated developers for each platform, which will manifold development costs. Luckily, there is an easy solution to this problem, called Cross-platform app development. Here is everything you need to know!

What Are Cross-platform Apps?

A cross-platform app is a mobile application compatible with several operating systems and runs flawlessly on multiple devices, including smartphones, tablets, desktops, wristwatches, and linked TV. These platform-independent applications offer several benefits:

  • 70–90% of the code is reusable
  • Easy maintenance and upgrades
  • Take less time to market
  • Increased visibility

What is Cross-platform Mobile App Development?

Simply put, cross-platform development is the process of developing a single mobile application that runs smoothly on multiple operating systems, in particular Android and iOS. The development is carried out in a single universal language that coders can easily export to any platform or operating system.

Since cross-platform development follows the “Write Once, Run Everywhere” (WORE) approach to build apps, developers have to write code only once. This eliminates the need for creating two separate apps for Android and iOS, which eventually saves time and money. Thus, being fast and cost-effective, cross-platform development is a go-to choice for everyone, specifically startups and small businesses.

What is the Difference Between Native and Cross-platform App Development?

The internet is flooded with the never-ending debate of native vs. cross-platform app development. However, both approaches have their pros and cons. Let’s analyze the differences in terms of:


Developers don’t need to write code multiple times in case of cross-platform development. On the other hand, native app development requires you to write different codebases for different platforms.

#Programming Languages Used

Cross-platform mobile apps are developed using the latest web development technologies such as HTML5, CSS3, and JavaScript. In contrast, native apps are built on top of native SDKs, IDEs, and programming languages such as Java, Kotlin, Objective-C, and Swift.


Native app development proves costly compared to cross-platform development. This happens due to multiple apps being developed for different operating systems.

#Turnaround Time

In native app development, the multiple versions of the app lead to increased turnaround time. On the other side, cross-platform app development allows you to build and then beta test your product rapidly.

How Do Cross-platform Apps Work?

Cross-platform applications are written in a single programming language, ranging from HTML and JavaScript to Python and Objective-C. Once the code is deployed, it’s forwarded to the so-called middleware. The middleware then converts the markup into the native APIs of platforms, such as Android and iOS.

How to Make Cross-platform Apps?

To build a cross-platform mobile app, you must be proficient in various programming languages and frameworks, such as HTML5, CSS3, JavaScript, Xamarin, React Native, Flutter, etc. Alternatively, you can hire mobile app development experts to build a custom cross-platform mobile app as per your specific requirements.

What Are the Challenges Faced in Cross-platform App Development?

With benefits come demerits as well! Some challenges that hinder the process of cross-platform app development are:

  • Limited tools and technologies available
  • Performance-based issues due to sluggish code
  • Difficult third-party App Integration
  • Finding problems in the entire code takes time

However, the advantages still outweigh the challenges of cross-platform mobile app development.
