What is The Best Framework for Mobile App Development in 2019?

Frameworks speed up the development, but there are too many of them today. Our developers shared their thoughts on the most popular ones to help you pick the one that fits your needs best.

April 1, 2019

Back in the early days of mobile app development, it was a very challenging field – a coder had to write in a language corresponding to a specific operating system. As a result, developers often ended up developing in languages they were not familiar with. That is, until frameworks entered the app development market.

Basically, a mobile app development framework allows a developer to create an app using the language they are comfortable with, and then the framework renders the code so that it can function across multiple platforms.

Despite the ease of developing for cross-platform use, some software engineers are still held back from using frameworks for app development due to not knowing which frameworks to choose.

If you haven’t made your mind up yet, here’s the ranking of top frameworks for mobile application development.

1. Xamarin

Thanks to its high code reusability and the option to create shared interfaces, Xamarin is often considered as one of the best frameworks for mobile app development among developers. One of its main advantages is that Xamarin offers high code reusability – up to 90%. However, it’s not the framework’s only benefit.



Despite of having quite a large development team, the mobile application framework is sometimes delayed in its updates and can be incompatible with the latest versions of iOS and Android. However, theses update delays normally don’t take long – the engineers on Xamarin’s team try to be as quick as possible about issuing new updates.

Apps developed with Xamarin

Being one of the most customizable and flexible frameworks for development, it’s no surprise that Xamarin is used by so many top corporations for app development.

Fox Sports

A Xamarin-backed app for Fox Sports created by Microsoft allows fans to keep up to date on stats from the latest game. With the use of Xamarin Visual Tools, developers managed to create a personalized experience and analyze thousands of data sources in a matter of seconds. Thanks to Xamarin Test Tools, the app was tested on thousands of types of devices, which led to its high-level mobile performance.


UPS used Xamarin to write a new version of its mobile app. Thanks to a shared codebase framework, the team was able to communicate faster and feel the differences in the efficiency of development. Moreover, it wasn’t too challenging to hire developers for the job seeing that C++ is a common programming language actively taught at most colleges.


Xamarin was used by Siemens as an empowerment of its mobile sketchpad tool. Thanks to the framework, developers were able to run the same interface on three different platforms (Android, iOS, Windows Phone).

Xamarin provided Siemens with the possibility to expand the experience of mobile sketches on different mobile platforms without having to write a native app for each one. The system was also a comfortable environment to work with seeing that the team was used to dealing with C++.

2. React Native

React Native is a technology stack for mobile app development created by the team of Facebook engineers that had previously developed ReactJS. It combines native development with JS interface development.

Unlike most other frameworks, React Native doesn’t use WebView to wrap code. The framework gives developers access to native mobile controllers to ensure apps look as native as possible.

Let’s explore the pros and cons of React Native.



Apps developed using React Native


The development team for the online tech magazine used React Native to develop its app. In one of their blog posts, the team remarked that the framework is “the first tool that truly delivers on the promise of cross-platform native app development.”

Facebook iOS and Ad Manager

The company initially created the hybrid mobile app development framework in order to help establish iOS support for the Facebook app. After seeing the improvement of the performance (mainly the speed), the development team used the framework to develop the Ad Manager app as well.


Another famous company that built an app using React Native is Walmart. The framework allowed the retailer to improve performance, create an interface that’s close to that of a native app, and ensure for smooth animations.

3. Cordova

Cordova is one of the most easy-to-use frameworks. It allows developers to create hybrid apps without writing a single line of native code. Still, among everything else, Cordova raises a lot of skepticism in the IT community.

Is there merit to this hesitation? To find out, we’ve broken down the pros and the cons of the framework.



Famous apps built using Cordova


The famous streaming search engine app used Apache Cordova to develop its mobile app. The framework supports an advanced database of titles as well as a broad range of filters. Despite the simplicity of the framework, JustWatch ended up being a very functional app.


Instabug is an app that allows developers to test their apps, detect and report apps, and collect feedback from beta testers. The application was developed using Cordova and is well-functioning considering what a large array of features the development team mapped out.

4. Flutter

Flutter is a framework dedicated to cross-platform app development. Developed by Google, it quickly gained popularity. Big brands like Alibaba or Google itself are actively using Flutter to develop their tools. Why has the framework become such a popular choice? Let’s break down its pros and cons.

Google Ads

The Google Ads app allows users to monitor their campaigns via Android. It showcases all the campaign details, sends real-time notifications, allows users to call a Google expert, and offers smart suggestions on how to improve a campaign.


Alibaba’s app is a mobile marketplace for wholesale trade. It incorporates Flutter to increase the speed and the performance of the app on different devices. It’s amazing how Flutter handles such a high-traffic app – millions of shoppers and sellers visit Alibaba on a daily basis.


Cryptograph is a finance app that provides users with the latest data on over 1,600 cryptocurrencies. It presents exchange rate charts, allows coin tracking, bookmarking currencies as favorites, and more. The interface of Cryptograph is lightweight and easy-to-use thanks to Flutter.


The introduction of frameworks has certainly made mobile app development faster and more comfortable. However, there are many choices of frameworks on the market and settling with just one might seem challenging.

In our experience, Xamarin proves to be the most agile and customizable framework for hybrid apps. The framework is just rich enough to write an entire app from scratch, it’s easy to share between team members, and your company can reuse entire chunks of code.
