Systems and methods for estimating relevant functionalities are disclosed. Example embodiments include a system for estimating relevant functionalities. The system may include a receiver adapted to receive incoming signals and a transmitter adapted to send outgoing signals. Additionally, the system may include circuitry coupled to the transmitter and receiver. The system may cause the circuitry to use the receiver to obtain information gathered from one or more applications supported by the electronic device. The system may cause the circuitry to remove a subset of personally identifying information from the information obtained. The system may determine an estimated user preference for a functionality of a set of functionalities using the information obtained. The functionality may correspond to an icon in an array of icons presentable on a display of the electronic device. The system may use the transmitter to communicate the estimated user preference for the functionality to the electronic device.
