This paper describes the development of a technological solution aimed at promoting under-digitized tourist destinations through a mobile application. The initiative arose from the need to raise the profile of tourist attractions that, despite their cultural and natural value, are not represented on global digital platforms. The proposal integrates a centralized repository based on georeferencing, developed with the Flutter framework and a client-server architecture under the MVVM design pattern, incorporating various APIs, mainly from Firebase and Google. To ensure the quality of the process, the agile Mobile-D methodology was used, allowing all phases to be executed in a period of four months. The validation of the solution included a software quality assessment according to the ISO 25010 standard, obtaining an average score of 3.9/5 in the applied usability sub-features. These results show that this model can significantly improve the visibility of emerging destinations and constitutes an adaptable basis for its implementation in different tourism contexts.
