This study developed an offline mobile application providing categorized, searchable access to essential electrical standards, including the Philippine Electrical Code (PEC 1) and selected international standards (ICC, NEMA, NETA, NECA). Designed for electrical engineering students and electrical engineers, the app allows offline access to important references. A developmental research design was used by creating a prototype, with usability assessed through a questionnaire on perceived usefulness and ease of use. The participants consisted of 30 licensed electrical engineers working in Pampanga. The study adopted the Input-Process-Output (IPO) model as the conceptual framework in the course of the study. The survey participants expressed high levels of satisfaction, most especially with regard to the accessibility and usability of the application. The study suggests that the work should be continued and updated in the future, and more technical standards should be added to subsequent editions.
