WideBrowser

When you build a responsive website (RWD), your iPhone always shows it at smartphone size.

Wouldn't it be convenient if your iPhone could also display websites at tablet size or PC size?

WideBrowser is a browser that switches its viewport width, so you can check the smartphone, tablet, and PC layouts of your website on a single iPhone.

FEATURES

1. Switch the browser width with one tap: Phone (320px) / Tablet (768px) / PC (1024px). Each width is customizable.
2. NEW – Comparison Mode: display all three widths at the same time and check every breakpoint at a glance.
3. NEW – Zoom Fit: scale a wide layout down to fit your screen, so you can see the whole PC page without scrolling.
4. Set a different user agent for each width.
5. Save websites to bookmarks — now with custom titles.
6. Landscape orientation and Dark Mode supported.

The width indicators show exactly which range of the page you are viewing, in CSS pixels.

Version 2.0 is a complete rebuild for modern iOS (requires iOS 17.6 or later). Your saved widths, user agents, and bookmarks from the previous version carry over automatically.
