POIViewer is a POI management tool with a lot of features. POIViewer can load, manage and display POIs (Points of Interest) on maps. Places, waypoints, placemarks can be imported and exported, show as pin or configurable icon on maps. This universal app is very fast even with thousands points, making it the perfect complement to existing apps for navigation or route planning. And if you really have a lot (>10000), you can selectively show/hide groups of POI on the map.
