How to Develop Cross-Platform Mobile Apps?
Table Of Content
Today, many businesses need to reach more clients through smartphones. This makes it important for apps to work on all smartphone operating systems.
Native apps are great because they work well and feel natural on any device. However, making two separate native apps can take time and money. That’s how the idea of making one app that works on different devices came about.
These kinds of apps, called cross-platform apps, are getting more popular. They let you use the same code to make an app for different devices. And because technology keeps improving, cross-platform apps can be just as good as native ones and cost less.
In this guide, we’ll talk about cross-platform app development. We’ll explain what it is, why it’s good, and give you tips on how to get started.
What is cross-platform app development?
Cross-platform app development means making apps that work well on different operating systems without being limited to one specific system.

Benefits of cross-platform app development
Here are examples of how various companies have benefited from cross-platform app development:
1. Code Reusability
React Native and Flutter are cross-platform frameworks that allow developers to write code once and deploy it across multiple platforms, such as iOS and Android. This saves time and effort writing separate codebases for each platform, reducing potential bugs and inconsistencies. An example is Airbnb, which used React Native to develop its app, enabling it to maintain a single codebase for iOS and Android platforms.
2. Faster Development
Walmart used React Native to speed up the development of its mobile app, resulting in quicker updates and new features across platforms. Cross-platform development typically offers faster development cycles compared to native app development. Developers can leverage shared code, libraries, and tools to expedite the development process.
With code reusability and faster development, cross-platform app development can be more cost-effective than building separate native apps for each platform. Delivery.com is an example of a company that saved costs by using React Native for its app, allowing it to reach both iOS and Android users without doubling their development expenses.
4. Consistent User Experience
Cross-platform frameworks enable developers to create consistent user interfaces and experiences across different platforms, ensuring a seamless experience for users. Bloomberg leveraged Xamarin to ensure a consistent user experience across iOS, Android, and Windows platforms for its news app.
5. Wider Reach
Cross-platform apps can reach a wider audience by targeting multiple platforms simultaneously. This broader reach can lead to increased user acquisition and engagement. Instagram is a prime example, using React Native to maintain a consistent user experience across iOS and Android, thus reaching a larger user base.
6. Easy Maintenance
Maintaining a single codebase for multiple platforms simplifies the maintenance process, as updates and bug fixes can be applied universally. Tesla used React Native to streamline maintenance for its app, allowing for quicker updates and bug fixes across iOS and Android versions.
7. Native Features
Cross-platform frameworks usually offer access to native device functions using plugins or modules. This lets developers use features specific to each platform. SoundCloud used React Native to access native features in its app, such as push notifications and background audio playback.
8. Rapid Prototyping
Cross-platform development facilitates rapid prototyping and iteration, as changes can be applied universally and tested across platforms simultaneously. Discord utilized React Native for rapid prototyping, enabling them to iterate quickly on new features and improvements.
Cross-platform apps can be more adaptable to future platform changes as they are less tied to specific platform technologies. Wix used React Native to future-proof its app, ensuring compatibility with upcoming platform updates and changes.
Step-by-step guide to developing a cross-platform mobile app
Now that we grasp the idea and advantages, let’s explore the practical actions for creating mobile apps that work on multiple platforms.

Choosing the right framework is important when you’re developing for multiple platforms. Options like React Native, Flutter, and Xamarin are great choices. Consider factors such as community support, ease of integration, and performance when choosing.
STEP 2: Define the App Architecture
Establish a clear architecture for your app. Determine how data will flow, how the UI will be structured, and how components will interact. A well-defined architecture sets the foundation for a scalable and maintainable application.
STEP 3: Optimize for Performance
While cross-platform development offers efficiency, optimizing performance is paramount. Pay attention to factors like rendering speed, app startup time, and overall responsiveness. This ensures a positive user experience.
STEP 4: Utilize Native Features Smartly
Make the most of native features on each platform to enhance user experience. While the codebase remains shared, incorporating platform-specific functionalities ensures your app feels native on each device.
STEP 5: Test Rigorously
Comprehensive testing is pivotal for cross-platform apps. Utilize testing frameworks compatible with your chosen development framework to identify and rectify issues across various platforms. This step ensures a seamless user experience, irrespective of the device.
STEP 6: Responsive Design
Craft a responsive design that adapts to different screen sizes and resolutions. This guarantees that your app maintains its visual appeal and functionality across a spectrum of devices, from smartphones to tablets.
STEP 7: Implement Continuous Integration and Deployment (CI/CD)
CI/CD pipelines streamline the development process, enabling automatic testing and deployment. Implementing CI/CD ensures that updates and improvements are efficiently integrated, maintaining a high standard of quality throughout the app’s lifecycle.
Challenges in Cross-Platform App Development
While cross-platform app development offers numerous advantages, it also comes with challenges you must navigate. Understanding these challenges is crucial for successful cross-platform app development. Here are some common hurdles:
- User Experience (UX) Consistency: Achieving consistent user experience across multiple platforms can be challenging due to differences in design guidelines, device capabilities, and user expectations. Developers need to carefully design and test their apps to ensure a seamless experience on each platform.
