Cross-platform app development has revolutionized the mobile app industry. Thanks to this technology, developers can create native-like apps for both Android and iOS devices at the same time. This translates into lower costs, shorter time to market and, therefore, maximized profits.

React Native

React Native is an open-source JavaScript cross-platform mobile app development framework that uses ReactJS to create user interfaces for iOS and Android devices. It was developed by Facebook and released in 2013. Facebook not only used it to develop its flagship app, but also others such as Instagram.


As stated on its website, Flutter is “Google’s portable UI toolkit for building beautiful, natively-compiled applications for mobileweb, and desktop from a single codebase”. Flutter helps you swiftly craft high-quality interfaces for both iOS and Android.


Xamarin is owned by Microsoft, is also open-source, and works on the “write once, run anywhere” (WORA) model. It uses C# as a single language (which means you don’t have to learn Swift or Java) and harnesses the power of the .NET platform to build native and performant apps for Android, iOS and Windows. 


With constant changes happening in the digital world, it is vital to stay on top of developing technologies.

What are Cross-Platform apps?

Cross-platform apps are not necessarily created with the language of choice of a certain operating system. In fact, they can be developed with a variety of frameworks that use the same language and codebase to make the app compatible with multiple operating systems.


What are native apps?

A native app is one that is developed using the language of choice of a given operating system. It’s the traditional way to build apps where Android apps are built using Java and iOS apps are developed using Swift or Objective-C.


What are the most popular cross-platform frameworks?

According to Stack Overflow’s 2020 Developer Survey, these are FlutterReact Native and Xamarin.


What are the different development technologies?

When it comes to development methodologies, there are plenty to choose from. However, the most popular ones are agile, waterfall and rapid. Agile methodologies are based on close collaboration between developers and stakeholders, early and frequent deliveries, continuous improvement, and great adaptability. The waterfall model is the most traditional method; it is quite rigid, extremely structured and requires plenty of documentation. Finally, rapid application development presents quite a stark contrast to the waterfall methodology by putting an emphasis on rapid prototyping and iterations.


Why are so many tech companies in San Francisco?

The San Francisco Bay Area is known for its tech environment, with Silicon Valley as the main tech hub for innovative technology companies around the world. Hundreds of companies choose San Francisco as their headquarters and many tech events take place in the city. Some of the reasons why tech companies chose San Francisco are the access to capital and an excellent business ecosystem, its cultural diversity and the various top-tier universities available in the area that provide an endless supply of talent.

Our San Francisco cross-platform app development company definitely followed their lead!


How do I choose a software company for my project?

Choosing the right software company can be challenging, but there are plenty of factors that can help you make the right choice when planning to develop a web or mobile app. For example, it’s important to check the app development company’s portfolio, focusing on their past projects. But it’s not just about making sure they can get the job done, you should also look for a company that is interested in your project and can give you honest input. Moreover, keep in mind that price and coding aren’t everything; a successful project trumps a cheap one, and design and user experience are just as important, so you should find a proper balance. You should also make sure the cross-platform app development company you choose has fluid communication, keeping you up-to-date with what’s going on with your project and giving you the opportunity to shape the expected product.

At the end of the day, choosing the right software company is not just about finding a competent software developer, but also about having a confident and trustworthy business partner.


Is Mobile Development harder than Web Development?

Both web and mobile app development have their benefits and their challenges. They also often use different programming languages and frameworks which can vary in difficulty and complexity depending on what your desired product will look like.

For that reason, we can’t really say that one is harder than the other. It is a matter of assessing your product requirements, finding the best fit and the right team to materialize your mobile or web app.
