What is a Cross-platform App?

Cross-platform mobile apps have the ability to run on various mobile platforms, such as iOS, Android, and Windows. Therefore, you do not require separate coding to build an app for each different platform. Also, you should know the complete difference between Native vs Cross Platform app development as well. Choosing the right app development type directly affects your cost as well.

Also, as the cross-platform is compatible with multiple platforms, it is easy to reach a broader audience.

With all the benefits, it is one of the most popular app development methods for startups and enterprises who are looking to resolve mobile application development challenges efficiently.

As we know about cross-platform apps, we will discuss all the benefits of cross-platform apps in detail. Let’s dive in to discover why a cross-platform is the right choice for your requirements.

What are the Advantages of Cross-platform Apps?

In this section, we are going to discuss the pros of cross-platform apps in detail, so you know how cross-platform mobile apps help your enterprise business grow.

  1. Wide Reach to Target Audience

    Building a cross-platform app means you can launch it on various mobile app development platforms, including the web. As Android and iOS hold a majority of the market share for operating systems, it is essential to build an app that targets both operating systems.

    So by developing a single app, you can target several platforms, such as iOS and Android. This helps you expand the reach of your products or services and increase revenue by making them available for both Android and iOS users.

  2. Lower App Development Costs

    The cross-platform app is developed based on the concept of ‘write once, run everywhere’. Additionally, when it comes to native app development for a specific platform, it is an expensive and difficult task to achieve. Therefore, it generally increases the cost of app development.

    However, this is not the case with cross-platform applications. This means you easily cut their development costs in half by developing cross-platform apps that run on various platforms. Hence, cross-platform app development is a more cost-effective approach to developing an app.

  3. Quick App Development Process

    Building a cross-platform app means you are able to launch the application in the market sooner. In addition, a similar codebase helps you to lower your efforts by 50 to 80%, helping you to be faster in the market.

    Suppose you are building an app for an Android device. Then you need to program in Java along with mastering mobile app development tools, such as Android SDK, Android NDK, and IntelliJ IDEA. This rule also applies to the iOS platform, where you need to program with Swift and other iOS app development software.

    But when you are developing a cross-platform app, you can use the same code for various platforms by using a “write once, use everywhere” approach. Therefore, it is possible for mobile app developers to deliver cross-platform applications within the estimated app development timeline.

  4. Reusable App Codes

    If you choose to build a cross-platform app, then you can use a similar code multiple times. This helps developers to save time as they can choose to avoid writing new codes for every platform.

    This saves time to develop an app as well as your resources by eliminating the repetition in the task of creating codes. Hence, with the cross-platform app, you can reuse the same code multiple times and save your app development time.

  5. Integration to Clouds

    The best part about developing cross-platform applications is that you are able to use a variety of plugins integrated with the cloud settings, as cross-platform apps are compatible with plugins.

    As you will be building a cross-platform app, you can infuse single source code with different plugins and extensions to improve the quality and performance of the application.

  6. Easy Maintenance and Deployment

    As a cross-platform app runs over several platforms, you only need to maintain a single application. This brings the benefit of maintaining and deploying code after the changes are made. Even, you can hire dedicated developer in case if you have complex mobile app to maintain.

    Whatever change you make will automatically be synced over all platforms and devices, helping you save time and money and maintain your app efficiently.

    Suppose you find a bug or defect in the codebase. Now, you are only required to fix it once, and it will get changed to all other places where the same code is used. This is how it is easy to maintain your cross-platform application by saving your time and money.

    We have discussed some of the advantages of a cross-platform app. However, just like every other app development approach, it also has its cons. In the next section, we are going to discuss the cons of a cross-platform app.

What are the Disadvantages of Cross-platform Apps?

Even though there are several advantages associated with cross-platform app development, it comes with various challenges. So let’s dive in to discuss the cons of the cross-platform app in detail.

  1. Poor UX/UI

    Building a cross-platform application means you run it over various platforms, including iOS and Android. So when you develop a cross-platform app, it isn’t easy to focus on the UX and UI design that fits every OS device.

    On the contrary, when you are building a native app, it is easier to focus on UX and UI design as you have to target only one operating system.

    Also, cross-platform apps use a single codebase for all the platforms; they can’t use all in-built features provided by mobile devices. Therefore, the UX/UI experience is poor in cross-platform apps compared to native apps.

  2. Lower App Performance

    You must be ready to face performance-related challenges if you are building a cross-platform app. It depends on multiple factors.

    However, in comparison with native apps, both having the same functionalities, the native app will perform better as native apps are specially designed for a specific platform, such as either Android or iOS.

    Even though cross-platform apps are easy to deploy, they may work slower than native apps as it is difficult for the developers to create mobile apps that perfectly align with native performance.

  3. Compliance

    Problems may arise when you try to integrate non-native components with native components to build a cross-platform app. This leads to creating inconsistencies in the app.

    Therefore, you will need to constantly readjust the design and functionalities of a cross-platform app to ensure that the app is running seamlessly on various types of platforms.

    It might create some challenges in the mobile app development process. However, you can hire experienced developers from a leading app development company to resolve such app development challenges.

  4. Low Security

    Apart from the lack of performance, cross-platform apps come with high-security risks, as cross-platform apps have lower update frequency. While in native apps, the software is less vulnerable to any security risks as there is a frequent update for native apps.

    However, whatever the app development approach is selected, the security threat is something that might occur at any time. Therefore, to address this issue, hire a top mobile app development company with experience building cross-platform apps for various industries.

  5. Poor Customization

    You might know that cross-platform apps support various native features. However, it is not always possible if development frameworks can’t support the required features of a cross-platform app.

    You may customize your cross-platform application. But on the other hand, it may limit you from integrating some of the essential features and hardware functionalities of an app, such as notifications, cameras, and GPS.

  6. Delay in Updates

    If any new update is added to the specific OS, it will take time for the cross-platform app to reflect the same updates.

    This is because the framework you will be using might not have been packed with the latest features of the latest version of the new release. This will result in late app updates.

    We discussed the major challenges you might encounter with cross-platform app development. However, you can streamline the cross-platform app development process with the following cross-platform frameworks. So let’s discuss them in detail.
