A small application, often denoted by a movable icon or window, runs atop other applications on the Android operating system. These applications offer quick access to specific functions or information without requiring the user to switch between full-screen applications. For example, a note-taking utility might reside as a semi-transparent icon on the screen, allowing for immediate jotting of information regardless of the currently active app.
The utility of such software lies in its ability to enhance multitasking and improve user workflow. Historically, the need for these applications arose from the inherent limitations of early mobile operating systems in handling multiple tasks simultaneously. Their existence addresses the requirement for readily available functions or data, contributing to increased productivity and a more streamlined mobile experience. Furthermore, they offer customizable interfaces, enabling users to tailor their accessibility options.
