Individuals’ main interest nowadays became to post pictures on their social media accounts of places they visited with their loved ones on special occasions or for tourism. However, finding measures that can improve the tourist attractiveness of a city is the main difficulty and an area of research. In this paper, we propose a multiplatform AI-powered mobile application that provides people with a guide to various events. The application uses collaborative geo-tagging and visualization of touristic and social activities through heat maps and images. The proposed application mainly consists of two features; uploading pictures of an attraction and visualizing the most visited locations through a heat map. Our results show that the proposed method is low-cost, user-friendly, and reliable and can be used to improve tourism and tourist attractiveness of a city.
