MyRadar is a free application for the iPad with one single purpose: to provide you with the most up-to-the-minute radar information for the United States. There are a ton of weather apps out there, but many times all you need to see is the radar.
Upon opening the app, you're presented with a map of your local area with animated radar displaying light to heavy precipitation. You can pinch to zoom in or out, and pan around the map. The date and time are displayed, and the radar animates in ten-minute increments. You can control the speed of the animation, and choose to view the road map or satellite image.
The radar is just as accurate as any other radar I've used, but the image is a bit rough compared with others. It's just not as smooth or refined as the radar at sites such as weather.com. Other radars use a five-minute interval for each radar image, while MyRadar uses a ten-minute interval. Obviously, the shorter the interval, the smoother the animation will look.
Being a free application, you can't complain too much about lack of features. However, it would be nice if you could save multiple locations, and choose which ones to zoom in on. It also would be beneficial to clean up the animation itself, just to make it look more refined.
Overall, it's a basic app that sometimes gives you just what you need, instead of all the extra weather information you don't really care about. It's definitely worth checking out.
