How to make an app for both iPhone and Android?

Today, Android is the leading operating system on the market taking up almost 73% of the market share, while iOS occupies only 26,4%. Thus, these platforms are widely used to build apps and get potential customers satisfied. To enhance and leverage your business, the app can be designed for both Android and iOS and there are two types of apps to consider – a cross-platform one and a Native app. See also tips for successful app development.

Cross-platform application development

Cross-platform applications are the applications that are specifically developed to run on a few mobile device platforms. For example, so as not to develop the app for the two platforms separately and adjust to Android and iOS requirements and possibilities, which takes more time and is 100% costlier, it is a good solution to deploy one app that adjusts to any platform it is intended for.

There are a number of ways to build cross-platform Android and iOS applications. For example,


With the help of Flutter

It is a mobile UI framework offered by Google that makes it possible to build iOS & Android native apps on both platforms, using a single codebase in a fast and expressive way.

Flutter development is carried out using the Dart – a programming language proposed by Google as well. Dart compiles Flutter into a native code, while Flutter uses Skia, the graphics engine, to draw UI components from scratch. With Skia the most complex animation will work fast.

Dart has features of both static and dynamic languages. And for those, who know Java, Swift, and C#, it will be easier to switch to Flutter. Introduction to Dart for Java Developers might help Java engineers learn Dart.

With the help of React Native

It is a successful cross-platform solution released by Facebook. It allows writing code in JavaScript which feels close to “native”. React Native is not only used for building cross-platform mobile applications with client-centric UI/UX but also allows AR and VR capabilities.

React Native uses JavaScript as its programming language and it is designed to deploy not only Android & iOS applications but also web ones. It offers platform-specific UI that feels like a native, has a reusable code and interchangeable adjustable modular architecture, has a simple and seamless UX, allows cross-platform apps to run on the web too, requires optimal performance, has a hive and hot reload function, is cost and time-efficient, has a well-developed ecosystem and a large, mature community.

Native application development

Native applications are developed for a specific operating system or device. Thus, software development differentiates Native Android from Native iOS applications. Native Android developers will use Java and Kotlin as the core of their app. iOS engineers will use Swift and Objective-C.

Native app development will offer high performance and 100% access to Android and iOS hardware. So, HD games, complex animation apps are better to be native as they will get access to local files and hardware and will perform faster and smoother. It takes more time to build a native app but you’ll never have to worry about the quality and user experience. See our custom Android apps development service!

How to make an app for both iPhone and Android?

Before making a decision about the technology to build a cross-platform app for both Android and iOS platforms, take into account the following factors:

  1. Effort – creating a cross-platform application will take less software engineering efforts than creating a native app for each platform.
  2. Price – creating one app for two platforms is cheaper than making two native ones. However, it will still depend on your app’s features, therefore, it would be best to consult with an expert.
  3. Features – if you don’t need to use native features of Android or iOS platforms, a cross-platform solution is the best option. However, if you want and need these features in development you should consider creating a native app for each of the platforms.
  4. Updates – a cross-platform app has a complex testing and updating process as the app has to be maintained to work accordingly on several platforms. However, you have to maintain one app. Frequent updates will be a bit easier in Native apps, but here you have to update two apps simultaneously to enhance the user experience.
