The application will be equipped with an alert system on all its pages.
The system will gradually check if a displacement of n meters has occurred from the last position by subsequently making an API request requesting all the markers within the set radius.
The API will have to return only the markers within the search radius.
Once the data is obtained, the distance between the user's position and the markers will be checked. If at least one marker is close to the user, the application will launch an alert.
