What are the key factors to consider while building apps for foldable devices?

We have come a long way in understanding the concept of foldable phones and their dynamic uses. Now we can come to the core part of this article where we can consider important key takeaways to consider while developing a mobile app for multi-screen devices. Here are the factors to consider while building a foldable version of your app.

Focusing on the quality of the app

Foldable smartphones are unique in nature, and most techies will buy them. These techies can belong to any level, like a business owner, a writer, a gamer, a tech enthusiast, and more. So, you have to focus on the quality of your app if you want to convert your targeted audience into regular users. Any point undermined in the quality will lack your app from being uninstalled from the phone. Your app should be smooth, adjustable to different screen sizes, and support flawless multitasking.

Test it more

An app working on 2 screen sizes requires heavy testing. Try to identify every flaw limiting a smooth experience for the user. Resolve as many issues as you can for a great multi-window configuration. Folded and unfolded, both versions of your app must be consistent in UI and performance with perfect rotational orientation.

Collect user feedback

Since foldable technology is new, there can be a number of errors and bugs that you might not be able to catch. In this regard, take extensive user feedback for foldable app development. Users can give you honest feedback about your app so that you can analyze them and take action to polish your app further.

How to build an app for Foldable devices?

With the understanding of factors to consider, it’s also crucial to understand how to build an app for foldable devices.

UI/UX design aspects to consider

Two states and screens for apps

In non-foldable devices, you have to focus only on standard screen sizes. Whereas in the foldable devices, you must consider two screens. And, with the two screens, you also have to consider two states of the app. In foldable devices like Samsung, you have to build three versions of UI/UX design– Unfolded, flat-opened, and half-opened.

For example, in texting apps, when the device is half opened, the keyboard comes to the half screen. You can use two classes while developing; STATE_FLAT and STATE_HALF_OPENED.

Multi Window support

Foldable phones are designed to boost productivity. With the multi-window support, the smartphone delivers a desktop-like experience to use multiple apps at once. Not only two apps, but a foldable phone also can run with 4 apps support at the same time, so you have to design your app according to that only. Drag and drop features are another important element to analyze so that your app delivers smooth and flawless multi-window support to your users.

Screen continuity feature

When we unfold a foldable device, it becomes a tablet. And the complete state of the app from standard screen size is transferred to the full tablet size screen. You must integrate the screen continuity feature excellently in your app. The complete flow of the screen should transform to the bigger screen flawlessly without any hick-ups.

You must set resizeableActivity = true to let your app automatically resize according to the user’s demand. Also, implement the right size, aspect ratio, and configuration to deliver an excellent user experience.

Technical preparations for folding app development

Add different screen ratios

You have to understand and analyze the market of foldable devices. Keep an eye on foldable devices like Oppo Find X, Samsung devices, and other smartphone manufacturer companies and study their aspect ratio. When you cover as many devices as possible, your app will universally work on every device.

Responsive and resizable technical components

Proper research and analysis will again play a key role here. From fonts to other design elements and technical elements, your app must excel in every department. Samsung provides a drag and drops feature for multi-window, and you must integrate android’s drag-and-drop framework. Apple is yet to step into the foldable market, so for now, Android is the only operating system you have to focus on.

What is the cost of building a Mobile app for foldable devices?

Foldable devices demand a unique feature set and development integrations, and this is why foldable smartphones are expensive. And so does the cost of building mobile apps for foldable devices. Your app’s complexity, features, functionality, and other elements will alter your app development cost. Yet on average, your app will cost you somewhere near $20,000 to $25000 or more, depending upon your requirements.

We advise you to consult your android app development company to understand the cost of your app development process for foldable devices.
