Systems and related methods for controlling delivery of a stimulus to a pinna of a subject with a stimulator worn on the pinna are described. A wearable stimulation device includes a mechanical, electrical, or other type of stimulator secured to a pinna of a subject. A personal computing device in communication with the wearable stimulation device controls delivery of stimuli and other aspects of operation of the device. The personal computing device presents various types of information relating to operation and control of the device to a user of the wearable stimulation device. In some aspects recommendations regarding neural stimuli and other stimuli or experiences to be delivered in association with the neural stimuli are provided via a computing system in communication with the personal computing device or the wearable stimulation device.
