Cross-platform development: The benefits and services for startups to build apps compatible with multiple operating systems and devices

Cover representing a single app on different devices as a result of cross-platform development

The pursuit for seamless user experience resulted in increased time-to-market and led to the birth of cross-platform development, a concept that allows developers to build applications compatible with different platforms utilizing a single codebase and let entrepreneurs save money on making apps for every type of device. But why is this concept important, and what else makes it so attractive and efficient for startups? In this article, we will explore the significance of cross-platform development, its inherent advantages, and a few startup services designed to help you build apps that provide users with a seamless experience.

Understanding cross-platform development

Cross-platform development involves designing software applications that are compatible with numerous devices and operating systems (OSs) like Windows, macOS, Android, and iOS. Unlike native app development, which entails writing unique code for each OS, cross-platform development centers on a more unified approach. Let’s dig deeper into the functionality and relevance of this technology in today’s digital ecosystem.


At the core of multiplatform app development lies the idea of ”write once, run anywhere”, which aims to simplify the development process and make it more cost-effective for businesses and developers. This is achieved by using frameworks and programming languages that translate the code into native components for each targeted platform. Some popular tools include React Native, Xamarin, and Flutter.

The cross-platform development frameworks help engineers to create apps with a single codebase, sharing most of the logic and functionalities, and minimizing redundant coding efforts. Moreover, these frameworks offer components and libraries that help to mimic native UI elements, ensuring that the application’s design and user experience align closely with what users are accustomed to on their specific devices.

Multiplatform development is gaining prominence with the rise of diverse user preferences, an expanding array of devices, and the increasing need for businesses to remain competitive. Today, users frequently switch between smartphones, tablets, and desktops, and expect a smooth experience across all their devices, meaning that apps have to accommodate varying screen sizes and resolutions while maintaining user-friendliness. Cross-platform development assists businesses and developers in devising apps that function on multiple platforms, enabling users to enjoy an equally seamless experience regardless of their device.

And with a continually growing collection of devices, cross-platform development proves to be more than a fleeting trend — it’s an essential means for businesses and developers to stay abreast of rapid changes in the digital landscape. As user preferences change and more devices flood the market, development for multiple platforms will remain vital for remaining up-to-date and satisfying user expectations.

Benefits of cross-platform development

Now that we’ve discussed some of the reasons behind this shift, let’s dive into the specific advantages of embracing multiplatform development:

Lower development costs. By creating a single codebase for multiple platforms, businesses can save on development time and resources, effectively reducing the overall expenses associated with creating separate applications for each platform. These cost savings enable startups with limited budgets to venture into the app market and potentially compete with more established players.

Reusable code. With cross-platform development, programmers create a single codebase that can be utilized across different platforms, reducing the time and effort spent on writing platform-specific code. This not only streamlines the development process but also minimizes the risk of introducing errors or inconsistencies across platforms.

Consistent user experience. A major advantage of the technology is that it delivers a uniform and consistent user experience, regardless of the device or operating system being used. By leveraging cross-platform tools, developers can ensure that their app’s design, UI elements, and overall feel remain consistent across platforms, thus promoting brand recognition and increased user satisfaction.

Time efficiency. Since cross-platform development requires writing a single codebase for multiple platforms, it allows developers to release apps simultaneously on different platforms. This ultimately speeds up the app development process and helps businesses get their products to market faster, which can be crucial in getting ahead of competitors.

Easy maintenance. Cross-platform apps are relatively easier to maintain and update compared to their native counterparts. Any changes, bug fixes, or updates applied to the codebase are automatically reflected across all platforms, eliminating the need to modify each platform-specific code separately. This simplification of maintenance and updating procedures ultimately saves time and resources for businesses.

From lower development costs to a consistent user experience, these advantages enable startups and established businesses to meet the diverse and ever-growing needs of the digital ecosystem more efficiently. In the next section, we will explore some startup services that can guide and support you in venturing into the world of cross-platform engineering for your applications.
