Here is a guide that will set you on the path to App development mastery.

What is cross platform app development?

Cross platform app development is a process of developing mobile applications that are compatible with several operating systems at the same time. By using this method, developers can come up with applications that can run on a single codebase. This helps to reduce app development costs. Traditionally, most app developers used to create native apps that could only operate in the mobile OS for which it was made. However, these apps were more expensive and took more time to create. Cross platform apps do not have these problems as they are made from the same basic code which saves a lot of time and effort.

Why opt for cross platform development solutions?

Developing mobile apps has always been a complex process. In native app development, developers working on back-end development have the added pressure of staying consistent and functional across multiple platforms. On the other hand, building native applications was easier even though it was expensive and time-consuming. With native app development, developers could not use the same code for a particular operating system. 

The good thing about cross platform development is that it offers some effective solutions to these common challenges. Through cross platform app development, it is possible to share a part of or the whole source code across multiple platforms. This means that developers only need to code the mobile assets once. 

Moreover, cross platform apps ensure greater adaptability and more stability for the developers and the end users. They also provide improved functionality and optimum user experience. The process followed in cross platform app development is very different from native development.

What does cross platform App do?

These applications have gained immense popularity in recent years due to the ever-expanding landscape of devices and operating systems, including smartphones, tablets, desktop computers, and web browsers. Here’s a closer look at what cross-platform apps do:

• Universal Accessibility: Cross-platform programs are designed to run fluidly across several platforms such as iOS, Android, Windows, and others. This universal accessibility ensures that users may access the app regardless of the device they are using, hence increasing the app’s user base.
• Faster Development and Updates: Cross-platform development frequently leads to speedier app development and upgrades. Developers may make changes to the codebase and apply updates across all platforms at the same time, ensuring that users receive the most recent features and bug fixes as soon as possible.
• Cost Efficiency: Creating apps for each platform separately can be costly and time-consuming. Cross-platform development frameworks, such as React Native and Flutter, allow developers to create code once and deliver it across several platforms, lowering development costs dramatically.
• Consistent User Experience: Cross-platform apps strive to provide a consistent user experience across all platforms. Users can anticipate comparable functionality, features, and design aspects, making it easy to adapt to the app across platforms.
• Wider Reach: Cross-platform apps can reach a bigger audience by targeting various platforms, which can be very beneficial for organizations trying to grow their customer base or improve brand visibility.

Benefits of cross platform app development

Let’s have a look at the distinct advantages of investing in cross platform app development solutions.  

1. Reusable code

One of the best reasons for choosing cross platform app development is that the same code can be repeatedly used for multiple OS versions of the same app. Unlike native app development, cross platform development does not require developers to write fresh codes for every OS. This can help to save time and resources as developers do not need to repeat the tasks associated with creating new codes.

2. Better exposure to the target audience

When you have a business app that has been developed with the cross platform approach, it can make it easier for you to target both iOS and Android users. Your app can also be accessed through the web. This means that you can readily reach out to the maximum number of potential customers through your app. 

3. Easier deployment and maintenance 

When you use a cross-platform app, you get to have a single app that is universally compatible with all the platforms. Therefore, maintaining the functionality of the app becomes a lot easier in such cases. You can also deploy code changes as and when you prefer. You can also sync any new updates that you launch on the app over multiple devices and platforms.  

4. Faster development process

Compared to native apps, cross-platform apps can be developed much more quickly. Since such apps only require a single source code, it can reduce overall developmental efforts by about 50% to 80%. Therefore, investing in a cross-platform app development project is a good idea as it can help to come up with a business app loaded with great features in less time. 

5. Reduced development costs

The developmental costs for the cross platform apps are lower than that of the native apps. The reason for this is that they are written by a single code, which means that less time and resources are used for developing these apps. The reusable codes can simplify the development process and this can bring down the costs required for developing these apps.  

6. Easier customization and faster time-to-market 

The cross-platform apps come with the added advantage of faster time-to-market (TTM) along with quicker deployment. This is because less time is devoted to writing the code for the app. Developers can also customize the app or tweak it easily to cater to the needs of their clients. 

7. Quicker integration with cloud settings 

The cross-platform mobile applications are readily compatible with the cloud settings and they can be integrated with different types of plug-ins. Developers can coordinate a single source code with different types of extensions and plug-ins so that the app becomes functional and flexible.
