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. 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 and 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.

Please visit our web site for more information.

Customer Reviews

Don't let $ put you off.

This is by far the most powerful radar app avaliable. It has all the all the reflectivity & velocity products, echo tops, VIL, surface rainfall, storm total rainfall, storm warnings, storm tracks to name a few that anyone from an amateur to a professional would need plus this update adds dual pol products as well.

For the first time RadarScope as add in app purchases which is $9.99 this adds real time lighting and up to 20 frames on super res reflectivity I wish this purchase could have been included but they have to pay to have real time lighting. I'm not sure but I think they could have included the up to 20 frames on super res with the update however to make the in app purchase seem more valuable it was put there but the $9.99 is for lighting detection fee they have to pay.

If you are an amateur or just interrested in learning more about weather I would highly suggest reading excellent FAQ on Radar Scopes page before purchasing it will get you more excited in something you are already interrested in and once you get the app you will already know what all the settings do, the tilts mean and what to look for in each product. If you are on the fence about this you are already interrested in weather or at least learning more I can't give Radar Scope enough praise for this after you read the FAQ play with the app it will get a spot on the first page of your device.

Continues to get better with each update!

RadarScope has always been my go to app for working in the field with severe storms and hurricanes the last several years. Worked amazingly as usual in Hurricane Arthur this past week. With this latest update, the new PRO option for lightning data and longer loops is very nice. I'd be willing to pay a little more annually for the pro version option if it could include surface plots / data. Not sure if it's possible, but it would be great having that option with radarscope on all my iOS devices and Mac. Keep up the updates! - Jeff Gammons

In-App Money Grab

This is an okay app - and is THE most expensive app I've purchased (at $9.99). But adding an in-app subscription for enhanced ("PRO") functionality as an upgrade to an already-expensive app really just stinks of a greedy money-grab. It'd be one thing if this app only cost a buck - but paying a premium price for an app shouldn't open the door for these in-app "pro" feature add-ons down the road. Way to stick it to your customers!

There are other (cheaper and frankly, just as good) radar apps out there. I encourage prospective buyers to really look at those before plunking down $10 for this app.
