Mobile app development for iOS and Android devices separately is a time-and-money-consuming choice. That’s where cross-platform development comes into play. This definitive guide will tell you everything you need to know about cross-platform mobile application development. Read on till the end!

In today’s fast-paced world, the mobile app market is expanding by leaps and bounds. Apps companies are getting introduced to new trends, technologies, and approaches now and then. Today, deciding to build a mobile application is easy but determining the right approach isn’t. The development approach (depending on your app’s requirements) can make or break your app. Therefore, picking the right app development approach becomes critical for businesses to succeed.

That said, the cross-platform app development approach has emerged as the unrivaled choice for businesses that want to develop Android and iOS apps within less budget. In fact, per Statista, around one-third of developers use cross-platform technologies or frameworks.
Businesses can create app solutions (for Android and iOS) quickly and cost-efficiently by leveraging the cross-platform mobile development approach.

What Is Cross-Platform App Development?

Cross-platform app development is about developing a single app that can run smoothly on multiple OS (mainly Android and iOS). In other words, the cross-platform approach allows developers to build mobile applications that are finely compatible with more than one operating system.

All in all, the cross-platform mobile development approach follows the “Write Once, Run Everywhere” (WORE) ideology to build mobile apps and eliminates the development of app versions for Android and iOS individually. It is one of the reasons why startups should go for cross-platform app development.

Popular Companies Invested in Cross-Platform Approach:

Companies are highly adopting this approach because it helps them save time, money, and effort. Some big giants, including Instagram, Wix, Walmart, Bloomberg, SoundCloud Pulse, and Google Ads, have already leveraged cross-platform development approaches and reaped its benefits. Consequently, you should also seek a reliable cross-platform app development company to develop a high-performing hybrid app and increase your ROI.

The Difference Between Native vs Cross-Platform App Development

The internet is flooded with the never-ending native vs cross-platform app development debate. Native vs cross-platform applications have always been a prevailing debate point for experts. Some find the native app development approach the best, and some experts prefer the cross-platform app development method.

Both native and cross-platform app development have their pros and cons. Native app developers write codes for iOS and Android apps separately to give users the top-notch experience; however, the cross-platform development follows the “writing code once and running it on multiple OS” approach.

You can’t declare a definitive winner in this competition. You can’t declare one as the “globally best” app development approach. Depending on the requirements, businesses can (and should) choose either of them to stand out in the crowd.

Top 7 Business Benefits of Cross-Platform Mobile App Development

Wider Audience Reach

A cross-platform mobile development approach allows you to build an app and deploy it over various platforms, including the web. It means, with a single app, businesses can target iOS and Android platforms and widen their audience reach and attract audiences from all over the world. Maximum audience exposure means more users, which will ultimately result in more profit indeed.

Code Reusability

For developers, writing good, reusable code is a good practice, but it’s a real bonus when this only has to be done once.

With the advanced tech and tools, hybrid apps can also match the performance of native apps if used the right way.

Cost-Effective Development

Native apps are expensive. Why? Businesses require to hire two different developers to build Android and iOS apps separately. However, with a cross-platform app development approach, one code is enough to work on multiple OS. That means businesses need to hire only one developer that will write a single code and run it everywhere. By doing this, developers can save time, and companies can save a lot of money, resulting in better ROI.
