Multiplatform Mobile App Development: An Ultimate Guide!

If you want to establish your mobile app business towards success, then your business can no longer afford to limit its mobile app presence to a single platform. This is where multiplatform mobile app development becomes relevant – a groundbreaking solution enabling you to build your app simultaneously and deploy it across all platforms.

Multiplatform development lets you create one app that works smoothly on various operating systems instead of having to manage two distinct codebases. This approach is efficient and cost-effective, saving time and money while simplifying maintenance—all without compromising performance or user experience.

Whether you are a startup or a well-established business, the ability to develop apps that integrate seamlessly across multiple platforms – including iOS, Android, web, and others – is revolutionary. This offers various opportunities, including expanding your customer base, enhancing user experience, and maintaining greater brand loyalty.  

Let’s investigate the way this state-of-the-art approach is changing our method for developing mobile apps.

What is Multiplatform Mobile App Development?

Think of a multiplatform app like a TV show that can be watched on different devices. This includes devices like phones, tablets, or even smart TVs. So, the content and experience will be the same regardless of your device.

An app is multiplatform if it functions across different operating systems, including iOS, Android, Windows, macOS, and web browsers. The app can be developed using various technologies tailored to each platform or a shared codebase. Still, the primary objective is to provide a seamless experience across all devices.  

Examples of Multiplatform mobile apps include Spotify, WhatsApp, Netflix, and Slack. 

Multiplatform Mobile App Vs. Cross-Platform App

While "multiplatform" and "cross-platform" are often used interchangeably, they have slightly different meanings in mobile app development. 

1. Multiplatform Mobile Development 

This is a broad approach where an app is built to run on multiple platforms (iOS, Android, etc). There are two ways to do this:

• Native Development: Separate apps are built for each platform using platform-specific languages (Swift for iOS, Kotlin for Android).

• Cross-Platform Development:  A single codebase is used for multiple platforms, like React Native or Flutter.

2. Cross-Platform App Development

These apps share some or all of their code across platforms. Instead of writing separate apps for iOS and Android, developers write one codebase that works on both.

• Example: If you build an app using Flutter, the same code runs on iOS and Android without needing to be rewritten it separately.
• Less effort, but sometimes small modifications are needed to match the platform’s design.

Key Differences:

Feature	Multiplatform Mobile App	Cross-Platform App
Development Approach	Can be developed separately for each platform (native) or using a hybrid approach.	Use a single codebase with frameworks like React Native, Flutter, or Xamarin.
Performance	Typically higher performance, especially if developed natively.	May have slightly lower performance than fully native apps, but it is optimized for efficiency.
Codebase	Can have multiple codebases (one for each platform) or a hybrid approach.	Uses a single codebase for all platforms.
Development Cost	Higher, since separate development efforts may be needed.	Lower, since a single codebase reduces development time & cost.
Examples	Microsoft Teams, Netflix, WhatsApp	Instagram, Facebook, Google Pay, Alibaba
Best For	Apps that need a full native experience or high performance.	Apps that require faster development and cost-effectiveness.

So, every cross-platform app is a multiplatform app, but not every one is cross-platform!

Advantages of Multiplatform App Development 

The appeal of multiplatform app development stems from a variety of compelling benefits that address key challenges in mobile application development:

1. Wider Reach and Market Expansion

An app available across various operating systems (iOS, Windows, Android, Web) can reach a broader audience rather than being confined to just one platform.

Companies can enhance their customer base without developing separate apps for each platform.

Example: Netflix operates on smartphones (iOS & Android), desktops (Windows & macOS), smart TVs, and even gaming consoles, making it available to millions of users globally. 

2. Faster Development & Deployment

Since developers can work with a single codebase (especially in cross-platform development), they don’t have to write and maintain separate code for iOS and Android.

This speeds up app creation, testing, and deployment, helping businesses launch products faster.

Example: Instagram uses React Native for parts of its app, allowing developers to build and update features simultaneously for iOS and Android.

3. Cost-Effectiveness

Cross-platform development is more cost-effective than building iOS and Android apps separately. In comparison to native applications, a cross-platform can be about 30% cheaper. 

Moreover, since developers can write a single codebase and deploy it across multiple platforms, it significantly reduces development time and effort.

Another major cost-saving factor is maintenance. With a unified codebase, updates and bug fixes can be implemented simultaneously for iOS and Android, ensuring consistency and reducing long-term expenses. 

This approach not only benefits startups looking for budget-friendly solutions but also enterprises aiming to optimize their mobile development strategy.

4. Faster Time to Market

Cross-platform development accelerates the app launch process by allowing developers to write a single codebase for multiple platforms. 

According to Statista, cross-platform frameworks like Flutter and React Native can reduce development time by up to 50% compared to native development.

Additionally, a Forrester report states that businesses using cross-platform development can launch apps 40% faster than those opting for native solutions. 

This speed advantage enables companies to respond quickly to market demands, gain a competitive edge, and generate revenue sooner.

5. Consistent User Experience

Cross-platform development ensures a uniform look and feel across different devices and operating systems. 

Businesses can maintain design consistency by using a single codebase, ensuring that UI components, animations, and interactions remain the same on iOS and Android.

According to a Gartner report, 75% of users expect a seamless experience across devices, making consistency a key factor in user retention. 

Cross-platform frameworks like Flutter and React Native provide pre-built UI components and adaptive design features, ensuring that the app delivers a native-like performance and cohesive experience, regardless of the platform.

6. Simplified Maintenance & Support

Cross-platform development simplifies app maintenance by allowing developers to manage a single codebase instead of maintaining separate versions for iOS and Android. 

This means bug fixes, feature updates, and security patches can be deployed simultaneously across all platforms, reducing downtime and ensuring a consistent user experience.

According to a Forrester report, businesses using cross-platform frameworks experience 30-40% lower maintenance costs than those with native app development. 

Additionally, streamlined updates help companies release new features 50% faster, enabling them to stay competitive and responsive to user feedback.

Challenges of Multiplatform Development

Let’s understand the challenges of multiplatform mobile app development are:

1. Performance Constraints

Cross-platform apps may not match the performance of native apps, particularly in scenarios requiring high processing power, such as gaming, real-time data processing, or AR/VR applications. 

Since they rely on intermediate frameworks like Flutter, React Native, or Xamarin, they may introduce slight delays compared to apps built directly with Swift (iOS) or Kotlin (Android).

2. Restricted Access to Native Features

Some platform-specific capabilities, including complex gesture detection, biometric identification, and complex operations, may not be fully supported by cross-platform frameworks. 

Developers usually have to write original native modules to bridge this gap, complicating and labor-intensively adding to the development process.

3. Platform-Specific Roadblocks

Despite the promise of "write once, run anywhere," each platform has its guidelines for design, UI behaviors, and system restrictions. 

It is challenging to build a consistent user experience without human adjustments because, for instance, Google's Material Design and Apple's Human Interface Guidelines differ in appearance, navigation, and interactions. 

4. Tooling & Development Environment Challenges

Cross-platform programming requires third-party frameworks and plugins, however, these may not always be fully optimized or updated with the latest operating system changes. 

Debugging can also be more difficult because developers may need to troubleshoot many sources, such as native components, the framework layer, or platform-specific APIs.  

5. Device & OS Fragmentation

Given the variations in screen sizes, resolutions, and hardware capabilities across iOS and Android devices, it may be difficult ensuring seamless performance and UI consistency. 

Furthermore, the incapacity of older OS versions to support more recent cross-platform updates may result in compatibility issues that call for additional testing and optimization. 

Choosing the Right Multiplatform Framework

Selecting the best multi-platform app development framework is a critical decision that significantly impacts the success of your mobile application project. 

It's not a one-size-fits-all situation; the ideal framework depends heavily on your project's specific needs, goals, and constraints. 

Here's a more detailed breakdown of the key factors to consider:

If your app demands high performance, especially for graphically intensive operations, complex animations, or real-time interactions, frameworks like React Native and Flutter are generally considered excellent choices. They offer closer-to-native performance compared to some other options, minimizing the performance overhead often associated with cross-platform development. Consider whether your app requires complex calculations, 3D graphics, or intensive data processing. If so, prioritize frameworks known for their performance characteristics.

2. UI/UX Considerations:

The user interface and user experience are paramount for app success. If your app has complex or unique design requirements, or if you need fine-grained control over the UI, Flutter's focus on UI customization and its widget-based architecture makes it a particularly strong contender. It allows for highly tailored and visually appealing interfaces. However, React Native also offers good UI capabilities, though it might sometimes require more effort to achieve the same level of customization. Think about the complexity of your UI, the need for custom animations, and the importance of a polished and unique user experience.

3. Development Team Expertise:

The skills and experience of your development team should be a major factor in your framework selection. If your team is already proficient in JavaScript and familiar with the React ecosystem, React Native might be a natural and efficient fit. This leverages their existing expertise and minimizes the learning curve. Similarly, if your team has a strong background in C# and .NET, Xamarin could be a more suitable option. Consider the existing skill set of your team, the availability of developers for a specific framework, and the time required to train the team on a new technology.

4. Project Budget and Timeline:

Budget and timeline constraints are often critical factors in project planning. If you have a limited budget or a tight deadline, frameworks like Ionic, which utilizes web technologies, can be a good choice. Ionic might allow for faster initial development and lower upfront costs. However, it's important to weigh this against potential performance trade-offs. Consider the project's overall budget, the desired launch timeline, and the potential cost of development, maintenance, and future updates.

5. Access to Native Features:

If your app requires extensive access to platform-specific features or APIs (e.g., specific sensors, Bluetooth functionalities, or advanced camera capabilities), you'll need to choose a framework that provides seamless access to these native functionalities. React Native and Xamarin generally offer good access to native features, often through native modules or plugins. Evaluate the specific native features your app requires and ensure that your chosen framework supports them or has readily available plugins or libraries.

6. Community Support and Ecosystem:

A strong and active community is invaluable for any development framework. A large community provides access to resources, libraries, documentation, and support when you encounter challenges. React Native and Flutter benefit from large and vibrant communities, making finding solutions to problems easier and staying up-to-date with best practices. Consider the size and activity of the community, the availability of documentation and learning resources, and the level of support you can expect.

7. App Complexity:

The overall complexity of your app should also influence your framework choice. A framework like Ionic might be sufficient for simpler apps with basic functionalities. However, for complex apps with intricate features, integrations, and performance requirements, React Native or Flutter are generally better suited. Consider the number of screens, the complexity of the data models, the need for offline functionality, and the overall architecture of your app.

By carefully considering these factors, you can make an informed decision and select the best multi-platform app development framework that aligns with your project's unique requirements and maximizes your chances of success.
