RadarScope is a specialized display utility for weather enthusiasts and meteorologists that allows you view NEXRAD Level 3 and super resolution radar data along with Tornado, Severe Thunderstorm, Flash Flood Warnings, and predicted storm tracks issued by the US National Weather Service. It can display the latest reflectivity, velocity, dual-polarization, and other products from any NEXRAD or TDWR radar site in the United States, Guam and Puerto Rico, as well as reflectivity and velocity data from Environment Canada radars. These aren't smoothed PNG or GIF images, this is native radar data rendered in its original radial format for a high level of detail.

Whether you are scanning reflectivity for a mesocyclone's tell-tale hook echo, trying to pinpoint the landfall of a hurricane's eye wall, or looking for small features like velocity couplets in the storm relative radial velocity product, RadarScope gives you the power to view true radial NEXRAD weather radar on your iOS device.

When there are any Tornado Warnings (outlined in RED), Severe Thunderstorm Warnings (YELLOW polygons), or Flash Flood Warnings (GREEN polygons) in effect throughout the US, tap the warning button in the top right corner to browse the list of current warnings, view the details, and even zoom to the selected warning on the map.

Pinch or stretch to zoom in and out. Drag your finger around the map to scroll. Tap the radar sweep button in the toolbar to switch radars. Select one of the 156 different NEXRAD radar sites and 45 Terminal Doppler radars in the US and 30 other radar sites in Canada, with the rotating radar beam representing each radar's approximate coverage area. Plot your current location by tapping the location button and optionally report it to the Spotter Network. Tap the play button to download and animate over the last six images. Display the names of over 25,000 cities and towns on the map as you zoom and scroll. Tap and hold the color legend to see the data values.

Meanwhile, RadarScope will retrieve and display updated data automatically and intelligently (approximately every 3 to 10 minutes, depending on the radar scan strategy).

You can display data from NOAA's public access web site, our optional WDT feed (the default), or your AllisonHouse subscriber account. Spotter Network members can report their location and view the locations of other spotters.

The RadarScope Pro subscription is an optional add-on data set. It provides access to real lightning data that animates along with the radar loop and up to 20 frames of radar data, including *extended loops* of "Super Res" Level 2 data. Super Res Level 2 data is still available to all RadarScope users without purchasing a subscription.

RadarScope Pro subscribers can also access RadarScope for Apple Watch and a data interrogation tool to quickly determine data values for specific radar pixels.

Please visit our web site for more information.

Customer Reviews

Since it came out years ago...still smokes the competition

I have had this app since it came out. Consistently the updates have continued to impress. Hands down weather an amateur, enthusiast, chaser, or meteorologist this app is for you. Since they have offered the $9.99 a year Pro subscription it has left any other app in the dark ages. Ability to incorporate allisonhouse data too if you use that for GR products it is more data than you ever need! It makes me so happy to know if am not home with my weather lab all the robust stuff there...that I can have everything I need to make serious analysis and decisions between my iPhone and my iPad. If you buy it and don't see it as a 5 star aren't using it right!


This is still my favorite and most used app on my iPhone. I am not very knowledgeable in most of the products that this app offers to the pro/hobbiest, but that does not mean that the app is not very useful to someone that wants extremely accurate radar and other things such as how much rain fell with a current storm, etc. One day I will review the instructions provided at the developers web site, and at others, to use everything this app has to offer.

Updates come often and they add a lot of good stuff each time.


One of the better weather programs in Apple App Store

Definitely a comprehensive weather program contained in app/capsule form. After using this app for over two years now for year around weather monitoring, it is still VERY adequate. It should be one in a serious weather watcher's collection of weather tools.
