No room for fluff and sunshine here! Base Velocity's RadarScope is geared toward serious weather hobbyists and storm trackers who thrive on data, number-crunching and attributing precise metrics to the unpredictability of nature.
The data comes from NEXRAD (Next-Generation Radar) weather reporting sites in the United States, Puerto Rico and Guam. One of the most revered features of the data is that it is unrendered (meaning, it's not smoothed out for the purposes of making it faster to transmit and load, and easier for your screen to process and display). At $29.99, this program isn't exactly an impulse download, but RadarScope's information is a lot more specific than simpler, less expensive apps.
Browse current tornado, hurricane and flash-flood warnings, or view summarized storm reports and lightning data. Use a touchscreen or trackpad to scroll around the weather map, zoom in on points of interest and even animate the radar on a selected area. RadarScope continues to update the map even as the program's in use.
It's available for the iPhone and iPad, and can also tag along with you on a Mac laptop. Users report that the interface is easy to use and the data stream is reliable.
Don't make any download decisions just yet, though. Keep reading for our last mobile weather app pick.
