Methods and systems for launching applications on a computing device are disclosed. An exemplary method may include gathering data in connection with a launch of each of the applications that indicates one or more events occurring in connection with the launch of each application. When an indication of a particular event occurring is received, one or more out-of-memory values are modified based upon the data and the particular event. The out-of-memory values are indicative of a priority in which corresponding background applications are killed from running in the background of the computing device when memory runs low. When memory runs low on the computing device, one or more of the background applications are killed based upon the out-of-memory values to leave background applications running that a user is more likely to launch than the killed applications.
