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.

Customer Reviews


I'm a professional meteorologist, former hurricane hunter and hurricane/typhoon forecaster. I also live in tornado alley. With 35+ years experience, including operating and teaching weather radars, I feel qualified to fully endorse this app. RadarScope is as good as it gets on any mobile device. The radar data is presented in its native form on black background that provides greater definition and fine-scale interpretation detail. I've used it several years now and the app refreshes data quickly and is always working when I needed it most. The developers are responsive and appear to care greatly about user experience. I hope they offer in-app subscriptions to alternative or higher resolution Level-II data sources in the future. What a great app for extreme weather enthusiasts! What a great app just to stay informed of threats when you are home or on the road. Buy it. It is worth it.

Apple Watch-unfriendly

This is an awesome app on iPhone. High resolution, high accuracy. I just got an Apple Watch, and RadarScope has decided to make me look for other radar apps with their idea that I will pay a monthly fee to see their product on my watch. Sorry, but I'll be paying someone else a one-time fee. I don't have a pro's need for advanced features. I'm not a tornado spotter. Requiring a monthly subscription just so I can see on my watch what I can see on my phone without a subscription is at the least not well though out and possibly just greedy. It was a good and reliable product.

RadarScope is great, but needs improvement.

Well, first of all, RadarScope is great! It has great radar functionality. Where it needs improvement in the Apple Watch app. As you need pro for simple functionality isnt smart. You could give it limited functionality like being able to save 1 radar without current location.
