5 Best Cross-platform Mobile App Development Tools To Use In 2021

In the current mobile-driven world, having a web presence is not enough anymore. You have to be where your audience is. The multiplying smartphone users signify where you should be operating your business; it's on their smartphone. Now, to be on their smartphones, you are required to develop a mobile app. Moreover, there are multiple mobile operating systems, and each requires specific technologies and tools for building mobile applications.

Developing different apps for different OSs will require an abundant amount of time, effort, and money. Furthermore, you have to write and maintain separate codebases, work twice to fix bugs or add new features. Seemingly, it is very challenging for a startup business with a tight budget. Thanks to Cross-Platform Mobile App Development Tools that enable enterprises to build mobile apps for multiple OSs using the same codebase.


Using these mobile application development tools, you can create and launch native-like apps and target a wider audience. In this blog, we will elaborate on 5 Popular Mobile App Development Tools that let you build native-like cross-platform mobile apps. Before that, let's check out some benefits of cross-platform mobile app development.

Single codebase

Unlike Native app development, in cross-platform app development, you only have to write an efficient and reusable codebase once and use it to create apps for multiple platforms. 


Since the codebase is reusable, it saves a lot of time and effort and lets you focus on the project's primary goal. 

Development speed

Cross-platform development accelerates the time to market and helps to meet deadlines by enabling you to develop multiple apps simultaneously. 

Cost-effective maintenance

App maintenance is inevitable and it comes into the picture once you launch the app for users. As you develop multiple apps from a single codebase in cross-platform development, you must maintain that single codebase only. It makes the process easier and faster.


When it comes to design, a codebase that compiles to different platforms helps keep a consistent look, feel, and user experience on all the targeted platforms.
