Chueca is one of the largest gay districts in Europe and the city goes out later than almost anywhere, so the map is busiest when other cities have gone home.
Map & Mingle shows you roughly where somebody is, never exactly. Coordinates shown to anyone else are snapped to a grid of about 500 feet, so you can judge whether meeting is realistic without anyone being locatable. Looking is free and needs no photo. Everyone is 18 or over.
We publish the real number of people on the map near Madrid on this page. If it is small, it says so. There are no invented profiles and no fake activity notifications on this service.
