Did you know that the global foldable phone shipments were expected to reach 3.2 million units in 2019? According to Statista, that number is forecast to grow to 50.1 million units by 2022.

If you're planning to develop a mobile app for foldable smartphones, here are the factors you must consider.

Build for Both Folded And Unfolded Screen

You need to develop an app for both folded and unfolded screens. When unfolded, the phone screen should look like a tablet with a lot of space for displaying full-length content. When the screen is folded, the foldable device should look like a typical smartphone and it should display the content in micro-mode to deliver information in bits and pieces.

Create a Seamless Experience for Users

Needless to say, maintaining a consistent user experience across different screens should be a priority.

Switching the device from folded to the unfolded state or vice versa should be automatic and seamless for end-users. When unfolded the device will be bigger, and the user may hold it with both hands just as in the case of tablets. In a folded state, single-handed use can be expected.

On top of that, the on-screen content should resize and flexibly accommodate the same in-screen content and clickable elements as when the screen is folded or unfolded.

Multiple Windows

Obviously, the main purpose of foldable smartphones is to provide users with larger screen real estate and better multitasking. In some cases, users might interact with a few multi-window apps. Keep that in mind when designing and developing your foldable application.

Adjust the Screen Ratios

Since you have multiple screen sizes with the same device, you need to maintain the optimum aspect ratios for all screens. It is crucially important to test your app for various screen ratios. This will ensure that your app is compatible with as many devices as possible.
