Aptraka WeatherTrak is an easy to use Apple Watch app that displays weather radar images of United States locations. Aptraka WeatherTrak utilizes realtime NOAA weather map data to display radar images for a number of large US cities as well as regions of the country. Cities or regions are selected by deep-pressing the map image and selecting the desired choice from the list thats shown. To refresh the radar map, double-tap the screen to display an updated image. Because of performance limitations, weather radar maps are display as fixed images and cant be pinch-zoomed or scrolled.
