Top Cross Platform App Development Tools and Frameworks in 2021

Having an amazing app idea is a huge achievement. But wait, don’t celebrate too early. Have you figured out on which platform do you want to launch? Relax! You do not necessarily have to figure out the best development platform. Just use any of the following cross platform app development tools and launch your app on multiple platforms.

The guidelines for iOS and Android app designs are distinct and require different development methods. In this scenario, if you choose to launch on both platforms, you have to develop the same app for both separately. It takes too much time, effort, and money. Thus to find the middle ground, we have listed these cross-platform app development tools in this blog.

What is a Cross-platform App Development?

Cross-platform development gives the flexibility of developing using a universal programming language like JavaScript that can be extended to platforms like Android and iOS. It eliminates the need of programming the same app differently for different platforms. In a nutshell, it is a ‘one-code fits all’ concept to mobile app building. Let’s have a quick look at the top platforms of 2021.

5. Apache Cordova

   Apache Cordova is a free-to-use open-source tool. This runs on Node.js and accesses various native device APIs, such as camera, compass, accelerometer, geolocation, messages, to name just a few.

   

   This tool allows developers to develop applications without any constraints. It has bagged hundreds of plugins for various functionalities. Apache Cordova has the best platform-specific workflow. It helps developers deal with various platforms, such as Android, iOS, Windows, and web apps easily.

   Some of the highly successful mobile applications that use it, such as JustWatch, Pacifica, and Gudog show how reliable this tool is.

6. Qt

   Qt is one of the best cross platform app development tools. Although this is a premium tool, developers can test a free trial version before buying the membership.

   

   It lets the developer code in the basic C++ language, and it converts the code seamlessly into various languages as per the guidelines of the native applications. And once the code is exported, the intuitive Qt interface lets you monitor on various platforms with respective devices.

   Relax! You do not have to own those devices, it has an in-built stimulator for all the devices like smartphones and tablets using the operating system. And if a function is not functioning as your vision, you can easily modify it through the Qt interface only.

   Facing a catch 22 situation?

   To pick out the perfect cross-platform mobile development framework, you need to compare them. Therefore, let’s compare the above-mentioned software development tools.

Cross-platform Mobile Development Comparison

On the basis of the G2 ratings and reviews, we have prepared a quick compassion table to simplify the selection of software development tools.

So, as per your most required features and needs, you can choose the mentioned cross-platform app development framework and start developing your own mobile app step by step that runs smoothly on various platforms.

If you are thinking about the benefits of cross-platform development, then continue reading our next section.

Benefits of Cross-platform Mobile App Development

1. Fewer App Development Efforts

   The development process is no joke, and it needs a lot of effort, and cross-platform development allows developers to go through that only once. By using a single code base, it saves a huge amount of effort which you can put in further enhancement of the app.

2. Less Application Development Cost

   Multi-platform app development cuts down the app development cost by a significant factor. Since you have to develop it only once, it cuts down the time and hence the cost. Check all the factors that impact the cost.

   

3. Easy to Implement on Multiple Platforms

   Cross-platform development not only makes it easy to create but also to maintain them. The various tools that we discussed above, can be proven a blessing when updating apps. The mobile app development tools let you modify it with simple languages and convert them to different platform-specific languages. This way, developers can update the app, not only on the single platform but all the platforms at once.

4. Cross Platform Uniformity

   Providing users with the best user experience is on the checklist of all mobile applications, and the cross-platform development exactly checks that. As it uses the same code base for all the platforms, apps achieve a uniform user experience across all the platforms. The mobile application will be intuitive to the user on any other platform as well.

5. Greater Reach

   Why restrict the user base to a particular single platform when you can launch your mobile application on all the different platforms and solve the problems of as many people as you can. You can target a broader issue and hence allow your business to grow wider.

Cross Platform vs Native Development

Before you know the prominent differences between cross-platform apps and native apps, you must understand what a native app is.

When an app is built specifically for a mobile app development platform, it is known as a native platform. This means, if you intend to build an app, particularly for an iOS platform, it will not run on the Android platform and vice-versa. It will also not compromise with data security as they are intended to build for a single platform.

On the other hand, cross-platform apps smoothly run on various platforms as they use a single line of code. Therefore, it takes less time and cost to build cross-platform apps and more time and cost to build native apps.

Let’s understand this better with the following image and the table:

Note: Cross-platform apps are also known as hybrid applications.
