What is Cross-Platform App Development?

Cross-platform app development refers to developing mobile applications that can be used on multiple platforms. This means cross-platform applications can be used in multiple operating systems such as Android and iOS.

Cross-Platform vs Native Mobile App Development

There are two ways of building apps for an operating system. One is native development, and another is cross-platform development.

Native apps are applications built for a specific platform, using a particular programming language. For building iOS apps Objective-C or Swift is used and for developing native Android applications Java and Kotlin is used.

Native development lets us create an app for a single platform. This means apps built for iOS devices won’t work on Android smartphones.

On the other hand, cross-platform app development allows developers to create mobile applications compatible with more than one OS. For instance, if someone wants to develop a game for Android and iOS, they won’t have to write the code twice for the platforms if they opt for a cross-platform framework.

The cost of developing a cross-platform app is lower as compared to native apps. But cross-platform applications will have hardware compatibility issues, whereas native apps can seamlessly integrate with the OS for which they are built.

There is another type of applications called hybrid apps that combine the elements of both web and native apps. Simply put, they are web applications placed inside a native shell.

Advantages of Cross Platform Development

1. Time and Cost-Effective

Since the application code can be reused for multiple platforms, you don’t have to worry about hiring separate developers. This will make the mobile app development process more cost-effective and also will reduce the time of development.

2. Reach a Wider Audience

Being able to publish an across multiple platforms at once also means that you can reach multiple groups of target audience with ease.

3. Easy to Maintain

Since only a single app runs on multiple platforms, making changes and deploying it will be a lot easier. If a component of the mobile app design needs to be changed, it can be modified once in the common codebase and reflected to all platforms.

4. Uniform Design and User Experience

Since the same app runs on multiple platforms, users will have an uninterrupted user experience if they plan to migrate from a device to another. UI elements will also be similar and recognisable throughout every platform.

Challenges of Cross-Platform App Development

1. Limitations in Accessing Native Components

Both Android and iOS smartphones have numerous components like battery optimization, location management, security features, and memory optimization that adds to their user experience. While developing cross-platform apps, these features may not be easily accessible as compared to native apps.

2. Not Suitable for Novice Developers

Developers who are new to app development may have a hard time learning the trade of cross-platform mobile app development. We recommend you to try out no-code app builders if you’re just starting out.

3. Performance-Related Glitches

Cross-platform apps are often known to experience performance-related glitches due to their inability to fully integrate with the operating system and device. Depending on the recurrence and nature of such glitches, they may tamper the user experience of the app.

What are Cross-Platform App Development Tools?

Now that you know what cross-platform app development is, we discuss this. Cross-platform development tools allow you to create apps for different platforms. There are various cross-platform tools on the market, and you choose one depending on the required features, programming language, and the price.

The Best Cross-Platform App Development Tools in 2020

Here are the most popular Cross-Platform App Development Tools you can use to create mobile applications in 2020:

1. Adobe Phonegap

Xamarin is from Microsoft Visual Studio. Similar to Adobe Phonegap, you can use it to create apps for Android, IOS, and Windows.

Xamarin uses C# and Ruby for coding. With its ease of usage and compatibility, it is no wonder that big companies like Foursquare, IBM, and Microsoft itself use this tool for coding. Moreover, it has a large community, and as you can share your code on the go, it helps group development and learning.

The apps that use Xamarin look like native apps because the tool uses native interfaces. Despite that, no matter what platform you are building your app, the code will be about 80% the same for all.

The downside is that even if the tool is free for individuals and startups, established enterprises need to pay for it. Other than that, developers strongly recommend using native app development for applications rather than Xamarin if they make extensive use of graphics.

3. React Native
