Baby Date: a mobile application for teaching nursing care to newborns in primary care.

Objective: to develop and validate a mobile application for teaching undergraduates about the first nursing visit to a newborn in primary care.

Method: methodological study with an Instructional Design framework; content drawn up from scientific documents on caring for newborns and their families, supported by the results of an integrative review on the subject. The Integrated Development Environment Android Studio 4.0.1 tool and the IntelliJ IDEA platform were used to build the digital technology. Experts validated content and students evaluated navigability.

Results: the final version of the mobile application contains 67 screens grouped into 12 sections with random access. The device is presented on the introductory screen; this is followed by content on the physical examination, neonatal screening, nutrition, oral health, the vaccination calendar, growth, development, danger signs, and accident prevention; at the end, there is a fact sheet and references. Audiovisual resources (texts, images, and videos) complement the application; experts presented a Content Validity Index (CVI) = 1.00; for nursing students all the items had a CVI = 1.00; only the item "layout and presentation" had a CVI = 0.95.

Conclusion: the digital technology received a satisfactory evaluation from experts and students. It is innovative in child health care, with the potential to be used in the teaching-learning process of nursing students.
