Automated modification of graphical user interfaces

Information that describes one or more touch events performed on a touchscreen display to interact with a graphical user interface (GUI) of a software application is received. A touch event density map based on a frequency of touch events on the touchscreen display as a function of touch event position on the touchscreen display is generated. One or more portions of the touchscreen display that received the highest density of touch events are identified. At least one of: dimension of the one or more graphical elements of the GUI associated with the one or more identified portions of the touchscreen display, a dimension of a touchscreen display area that corresponds to the one or more graphical elements, and a position relative to the one or more graphical elements of the touchscreen display area are modified.
