Trendsmap is worth noting here, but this is a web app not a mobile app. It provides real-time social media trends around the world based on hashtagging culled primarily from Twitter, but has sourced from YouTube, Foursquare and other major social media platforms to provide a survey of what's happening around the globe on social media at a local level. I recall first learning about Cairo's Arab Spring the night before it began by checking out a tag cloud over the Egyptian capital with many references to #Tahrir. Visit Trendsmap for round-the-clock social media trends around the world and zoom in and out of the map to get a pulse on what's trending in your city or community.
