Many cell phones come with a variety of pre-installed applications meant to enhance the mobile phone experience. Additionally, some mobile phone operating systems have access to online marketplaces where owners may download more applications. Installed applications utilize the phone's system resources to perform their tasks, and some applications are able to run in the background so other applications can be used. However, running applications usually slows down the phone and detracts from system performance. Closing any open applications may provide a solution for slow phone performance and improve the functionality of other applications.

- Android handles applications in a manner that might be unfamiliar to most computer users. Most Android applications don't have a native "Close" option. Once a program is exited, Android will place it in a "stopped" state where information is saved until the system resources are requested for a different application.
