Monitoring children's health is of fundamental importance. With the widespread use of Android phones, applications to improve health services have become an option. This study aimed to comprehensively describe the development phase of an Android application (app) for healthy children in Indonesia, conducted in March-October 2021. The DEPA app was developed in the Indonesian Language (Bahasa) and is an acronym for Desain Aplikasi Pertumbuhan dan Perkembangan Anak or children’s growth and development app. The DEPA app uses 4D theory which includes defining, designing, developing, and disseminating. Focus group discussions were conducted with stakeholders to determine the needs assessment, find concepts, and develop content, features, and functions. The eligibility score for the assessment by media and material experts was 4.12, while the usability testing
using PSSUQ was 1.8. Results showed the DEPA app was successfully created and available on the Play Store. The analyses showed that the media and content scores were 4.5 and 4.3, respectively, while the PPSUQ was 1.8, which means it has good usability. The DEPA app is a new approach to health
children monitoring which has the potential to be implemented by mothers, cadres, early childhood teachers and health programs.
