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. 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.

Superb app and fantastic new upgrade

RadarScope is one of those apps where you are glad that went ahead and purchased it. With the new version (for the Mac), the UI has been changed but the new version has a much cleaner look. RadarScope is the best radar app you will ever find. I have both the Mac and iOS platforms. Resolution is outstanding!! I would recommend that you also purchase the Pro - an annual $9.99 which gives you Super resolution in the Velocity and Reflectivity and also has the Lightning. Please note with RadarScope, you are getting the radar feed that is rendered in it's original format. What you are viewing is not smoothed out (and why would you want it to smoothed out anyway). If you are certified spotter, RadarScope is integrated so that you can connect to the Spotter Network.

Technical support if you have a problem is exceptional. I would give the App and the tech support and the developers 14 out of 10's that impressive!!

Favorite app. Here's why...

Update: Here is my number 1 request: an easy way to toggle between reflectivity data and velocity data, the two products that I use 98% of the time.


This is my favorite app in the entire App Store. When I need to know if rain or severe weather threatens, this is my go-to app. The imagery is beautiful. Also, for $10/year, I help keep my family safe by knowing where lightning is striking.

I love the update and can't wait to use the feature of being able to step through, at my own pace, recent radar imagery. Also, that makes it easy to share the image from the loop that is of most interest.

The cost of this app is measly compared to the peace of mind knowing that I can track rain and storms while I'm on the go.

Yes, this app contains lots of stuff that the average user doesn't care about, but users can easily ignore those options from the menu. In fact, lay users probably won't even want to scroll through the menu of options---they'll simply choose one and be done with it.

However, for the curious, a simple google search of how to interpret the velocity data can help them begin to really explore one of the many merits of this app: finding rotations in storms that can lead to tornadoes.

Weather radar at home, at work, or on the go---awesome!

Best radar app

Hands down the best radar app. Only issue is the apple watch version. Just upgraded to pro to have it on the apple watch and it has a circular view on it (just like the previews in the App Store). It does not fill the screen properly. It seems like it was made for a circular smart phone and not made to fit the apple watch. Now on the other hand it looks fine in the glances view but it is not animated in glances. Just a thought for the next version.
