See how your website looks on the new iPhone Duo in folded and unfolded views. Try the interactive preview, test your layout, and spot responsive design issues before your visitors do.
Foldable phones are changing the way people experience websites. A page that looks perfect on a traditional phone may feel very different when the screen opens into a wider layout.
To make this easier to understand, Finepher created a simple interactive tool that lets you preview any website on the new iPhone Duo.
Check your website NowWhat is the iPhone Duo website preview?
The iPhone Duo website preview tool lets you enter a website URL and see the site inside a realistic folded-and-unfolded phone frame.
You can interact with the preview and swipe to fold or unfold the phone. This gives you a quick visual idea of how your website may look across both screen states.
Why should you test your website on a foldable phone?
Responsive design is no longer only about desktop, tablet, and a single mobile screen. New device formats can introduce different screen sizes, aspect ratios, and interaction patterns.
Testing a website on a foldable device can help you identify issues such as:
Content that does not adapt well when the screen becomes wider
Navigation that feels awkward across different screen states
Images or banners that have unexpected proportions
Buttons and forms that need better spacing
Layouts that look good on a normal phone but feel unbalanced when unfolded
A quick way to preview your website
You do not need to rebuild your website just to get a first impression. Open the tool, enter your website URL, and the website will be displayed inside the iPhone Duo frame.
Then swipe the phone to move between the folded and unfolded views. It is useful for website owners, designers, developers, agencies, and anyone preparing a new website.
It is a preview, not a replacement for real-device testing
The tool is designed to make visual testing easier and faster. It should not replace testing on a real device, because browser behavior, touch interactions, performance, viewport handling, and device-specific features can differ.
Think of it as a quick first check: before spending time on detailed device testing, you can use the preview to see whether your layout makes sense in both folded and unfolded states.
Try it with your website
