How to Move Your App to Another Platform?

In case you have an app that is built for iOS or Android platform, but you are looking for an opportunity to make it cross-platform, this article is definitely for you.

How can you move an App?

You should keep in mind 4 points, if you’re going to move iOS app to Android or vice versa: requirements capture, development, design, and testing.

Requirement capture

This stage is obviously the fastest part when moving an app to a new OS. As we have an existing app, our team can use it as a guide. So there is no need to write new specifications one more time, schedule myriads of Skype calls, and answer loads of mails.


When it comes to moving an Android app to iOS platform, we should remember that we don’t need just to substitute Android code by iOS code. It doesn’t actually matter whether you want to move an Android app to iPhone or quite the reverse, you have to develop an app all over again.

During the process of building an app for different platforms, you should remember that every platform requires knowledge of its peculiar features. You cannot do this just by changing code in a different language. When we design an app for multiple platforms we need to bear in view the fact that we’ll work with various hardware configurations, operating system support, and customization.

Hardware Configurations

When building/moving an app, developers should keep in mind that depending on the type of device, hardware configurations will be changed. Well, in spite of the fact that Apple is producing all iOS devices, we have a fair amount of iPhones and iPads. When it comes to Android devices, there’s much more companies producing them. From the developer’s point of view, it implies that every device will deffer in, for example, screen resolution, layout, processor architecture, memory, buttons etc.

When our team is dealing with an iOS app, we make it compatible with the current and the previous versions of the iPhone. Speaking about Android, we use most in demand devices.

By the way, user-friendly interface no less important than hardware configurations. Appropriate sizes, fonts, screen resolutions etc. really make sense.

Our experience allows us to work seamless as we know all the pitfalls and we are able to handle with them.


Speaking about developing/moving an app, it’s impossible to make no reference to customization side. Are we really so free to choose how we are going to build an app? The fact is that iOS is a closed-source operating system and Android’s source code is released under open-source licenses.

Do we have any limitations? Let’s see.

You might have thought that when developing an app for Android you have more freedom, and you’re able to customize everything. Probably yes, but still you’re working with platform-specific issues and your possibilities will be somehow limited. For example, Slow Motion feature is really a challenge for Android devices. Android phones have poor hardware support for such kind of video recording.

But it comes without questions that we should develop a component both for iOS and Android. If we want to build a good app for iOS, we’ll definitely move it to Android and vice versa.


Hopefully, there is no need to say that if you want to move an app to another platform, you should be in the know of platform’s standards and common user behavior.

And one more time, when we move, for example, an iPhone app to iPad, or any other wearables, we take into account screen sizes and resolutions, and user interactions which can greatly vary across these devices.

In case when an existing app has some distinguishing features which have won users’ love, we need to save them but it’s better not to copy-paste all the code.

What is the best, but the most challenging way to create design of an app you’re going to move to another platform? Adhering to platform specifics while remaining true to a brand’s values can satisfy all design criteria.

Testing and support

During the process of moving an app for another platform you need to be sure it won’t fail all the time. That’s why make some effort to spend plenty of time on testing. You know, the more devices and OS’s we have, the higher chance to find some bugs is. There is only one way to build a bugless app – testing it at all the stages of development.

Softheme has a great number of QA engineers who can ensure high quality of applications, so our clients can be sure that all critical bugs will be detected and fixed instantly.
