World Wide Hearing is a non-profit organization that provides youth in developing countries with access to
affordable hearing-aid devices [10]. Their requirement was an application that could capture hearing loss’ patient
data and hearing-aid device sales and follow-up visits by the hearing-aid technicians, map GPS location of the
patients visited and integrate monitoring and evaluation questions. Given our experience with Solar Ear and the
versatility of Magpi, we realized Magpi would be the optimal solution for World Wide Hearing needs.
