Tap Bar
Tap Bar is a bottom-bar navigation element that helps users move among top-level sections quickly, often used in mobile apps.

A tap bar (often called a bottom navigation bar) sits at the lower edge of a mobile interface, providing quick links to the app’s primary sections. With distinct icons or short labels, each tap bar button leads to a different high-level area—like Home, Explore, or Profile—preserving navigation consistency across screens.
Apps favor tap bars when top-level destinations all share importance. Users gain easy access to the app’s main parts without delving into menus, letting them pivot swiftly. The persistent presence of a tap bar ensures orientation, so users always know how to move to another major section in a single action.
