For those who like to follow weather more closely, there are a fair number dedicated radar apps to fill the void. Three of the most popular are Radar In Motion, Weather Radar, and RadarScope.
As their US$1 price tags suggest, Radar In Motion and Weather Radar are aimed at the masses--interested amateurs. RadarScope, priced at $10, appears to be designed with "professionals" in mind--perhaps meteorologists, but also those who might need the most up-to-date and reliable information available for their vocations or avocations.
None of these apps provide general weather forecasts or videos or even simple information like the current temperature. So if you want the most complete weather information, in addition to one of the apps reviewed below you'll need to add at least one general weather app or mobile web site.
Radar In Motion is developed by , which makes a of the same name.
While Radar in Motion does an adequate job of pulling public domain National Weather Service information for a locality and smoothly displaying animated radar for that area, it's lacking in many features that seem desirable. Zooming, for example, results in a more heavily pixilated version of the same images, instead of more detail. Panning results in a black screen, a spinning wheel, and a fairly long wait time until a new map loads.
