Safari is the built-in browser software on the iPhone, and it offers features such as bookmark management, tabbed browsing, advanced browser settings, and the ability to automatically fill in usernames and passwords. As the web-browsing capabilities of Safari gradually became insufficient for users, more and more alternative browsers have emerged to address Safari's shortcomings. Especially on the limited screen space of an iPhone, every bit of space is extremely valuable.
