A method and apparatus for dynamically composing applications is presented. A computer system identifies a set of parameters based on user input. The computer system then activates a portion of a plurality of capsules stored in a data storage to form a set of activated capsules based on the set of parameters. Further, the computer composes an application in real-time using a base capsule and the set of activated capsules in which the application is specifically tailored for a particular state. The application and the plurality of capsules take up a reduced amount of memory space.
