BrowserX3 is available for free on Google Play and the AppStore, which allows you to open three browser windows at the same time. When you start it, the horizontal orientation is automatically turned on and the display is divided into three equal parts.
In each such window, you can open any site. In the header, in addition to the search bar, there are buttons for moving to the next and previous pages, as well as a button that allows you to expand one of the browsers to full screen.
The expanded view also displays buttons for bookmarks and standard link exchange through other applications and communication modules.
Using BrowserX3 on a smartphone, even with a large screen, will be inconvenient, but just right for a tablet. Such an application can be useful for comparing text on different sites or, for example, watching YouTube videos while working in parallel on other resources.
The standard price of BrowserX3 for Android is 1 rubles, but now you can download it for free. Likewise with the iOS version.
