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, special marine and snow squall warnings, and predicted storm tracks issued by the U.S. 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, Puerto Rico, Korea, and Okinawa, as well as data from Environment Canada, Australian Bureau of Meteorology, Finnish Meteorological Institute, and German Weather Service 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 weather radar data.

RadarScope displays tornado, severe thunderstorm, flash flood, special marine, and snow squall warnings issued by the U.S. National Weather Service. You can browse the list of active warnings in the information sidebar, select a warning to view the details, and even zoom to the selected warning on the map.

Zoom in and out on the map using the mouse or pinch gestures on multi-touch trackpads. Click and drag to scroll around the map. Select one of the 307 different radars in the United States, Canada, Australia, Germany, Korea, Puerto Rico, Guam, or Okinawa. Tap the play button to download and animate over recent images. Display the names of over 25,000 cities and towns on the map as you zoom and scroll. Move the cursor over the color legend to see the data value associated with each color. You can also export the currently displayed map to several common image formats.

Meanwhile, RadarScope will retrieve and display updated data automatically and intelligently (approximately every 2 to 10 minutes, depending on the radar scan strategy).

You can display radar data from our servers, NOAA's public access web site, or your Allison House subscriber account.

RadarScope Pro is an optional auto-renewing subscription with two different tiers to choose from.

RadarScope Pro Tier One is an annual subscription that provides access to real-time lightning data in the U.S. and Canada that animates along with the radar loop and up to 30 frames of radar data, including extended loops of super-resolution data. Tier One subscribers can also access optional dual-pane and quad-pane modes for viewing multiple radar products side-by-side.

RadarScope Pro Tier Two is an annual or monthly subscription that combines all the features in Tier One with more advanced features, including SPC outlooks, mesoscale discussions, local storm reports, hail size and probability contours, and azimuthal shear contours in the U.S., a 30-day archive of all radar products, and the ability to use subscription features across multiple platforms.

If you choose to buy the RadarScope Pro subscription, it will charged to your iTunes account. The subscription will be auto-renewed within 24 hours prior to the end of the current period at the same price you originally paid. Subscriptions may be managed and auto-renewal disabled via your iTunes Account Settings after the purchase. Once purchased, the subscription cannot be cancelled during the active subscription period.

Well done....but a couple fixes...

I have used this weather app for a very long time. The new Apple TV version is nearly perfect (thank you for offering it), but it needs to retain what tilt you have he radar set at when selecting the source like it's brothers versions, it always defaults to 1, in Tampa Bay we have alot of "fuzz", and normally use tilt 3, please fix this or offfer a option to save it (which I cannot find). On a side note.... I know radar people do not like 'smoothing', but at this point would be a nice option with level 3 radar for general use folks.

Well done as far as it goes...

PROs: Superb for looking at any one radar site and all the different kinds of data that site outputs in full resolutionl. If you're interest in radar goes no further than one radar site, this is the app for you.

CONs: No composite view of all sites. Come on RadarScope, this is entry level stuff that is freely available elsewhere. If you're interested in exploring radar here and there, it will be tiresome. Next, loops are only 5 images, about 5 minutes worth. That's a big limitation for me and for anyone who is interested in the big picture. Finally, the base map is just just county lines. If its not your local area, you may find it hard to tell where things are at.

Overall, what you get is done superb. It's what you don't get, that's disappointing for a paid app in this price range. Of course they offer more features, that will fix what they have crippled in this software, for a monthly or yearly fee. For me it feels like I'm being squeezed for more dough a little too much.

Over priced and exploitative subscription pricing vs. iOS

I've been a long time RadarScope user on iOS and Pro subscriber... I went ahead and purchased RadarScope for MacOS as a convenience factor despite it not offering any difference in functionality and the frankly exorbitant price in comparison to the iOS version. I soon discovered that despite my having a pro subscription (that works across iOS, iPadOS, and tvOS devices) I was not able to restore my subscription on the MacOS version. The RadarScope policy evidently requies yet another subscripton to work on the MacOS version and will not share my existing one (again despite offering no difference in functionality... and working across multiple other platforms). The app itself is good... the pricing and company policy are extremely dissappointing and feel exploitative. I'll be looking to replace RadarScope with other alternatives sadly.
