Objectives: to describe the construction and validation process for a mobile application for development of the nursing history and diagnosis.

Methods: methodological study conducted in 2018 in three stages: content creation, based on the Basic Human Needs categories and nursing diagnoses; content assessment by nine nursing judges, with calculation of the content validity index; and construction of the application, which included definition of the requirements, a conceptual map, implementation and prototyping options, tests and implementation.

Results: the application was organized by sections: Grouped Basic Human Needs, Cranial pair tests, Clinical assessment scales and Additional tests. Two section were adjusted according to the judges' suggestions.
