RadarScope is a specialized display utility for weather enthusiasts and meteorologists that allows you view NEXRAD Level 3 and Level 2 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 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, select a warning to view the details, and even zoom to the selected warning on the map.
Use the mouse or trackpad to zoom and scroll the map. Click the radar selection button in the toolbar to switch radars. Select one of the 289 different radars in the United States, Canada, Australia, Germany, Korea, Puerto Rico, Guam, or Okinawa. Plot your current location by clicking the location button. Click 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 values.
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 animated lightning data and up to 30 frames of radar data, including extended loops of super-resolution data. Tier One subscribers can also access a data interrogation tool to quickly determine data values for specific radar pixels and an optional multi-pane mode for viewing up to four 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 50-frame loops, SPC outlooks, special weather statements, 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, a 2-year archive of NEXRAD Level 3 radar products, a full historical archive of NEXRAD Level 2 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.

Ratings and Reviews
Fantastic, except for Apple Watch version
The iPad version of RadarScope is unsurpassed for this weather geek; haven’t seen anything better. However the Apple Watch app version is very disappointing. I have removed it. It does not know what it wants to be. I need an untethered Watch radar app to use when out on a run, walking the dog, or on a ride. Although it is intended to work while untethered, with my usage and Verizon etc, it loads a radar image less than 10% of the time I try to use it untethered. 90% of the time it loads nothing or occasionally returns a “failure to to connect to parent app” error. I have gotten caught in downbursts that I could have avoided if the app would have shown me local radar and/or lightning when I needed the info. In addition, I do not need to see, on my tiny watch screen, the myriad different products available from my local radar station (KLIX); that is what my iPad/phone version is for. Finally, I do not find the watch app to be useful in tethered mode either; I inevitably would rather have a look at the radar on my phone instead. Please redesign the watch app to be reliable in untethered mode even if it means losing many of the specialist radar products.
The other reviewers are right-- this is the best radar and well worth the cost. I had purchased several others and put off this one because of the price. The other apps disappointed-- they have been inaccurate or slow to update. This one is precise and quick--so far is has never been more than a minute or two before it updates and most often it is up to the moment. And the accuracy has been brilliant. It has many features that I have not yet used, but i hope to learn them soon. I'm a weather novice, but I definitely want to know where the storms are, where they're going, and how much rain we'll get. This is the best radar by far!
Update: the developer keeps refining an already brilliant application. This is THE radar application, far superior to any other out there. Absolutely one of the best purchases I've ever made for my iOS devices—beautiful on the iPad, crucial app on the phone, and a very informative glance at the radar on the watch.
I bought the upgraded pro version and like the additional features: longer loops and lightening info. As with the basic version of this app, the cost is there but well worth it: this radar and all the features are the some of the best things on my phone. One of the top apps of any kind and one I will subscribe to without hesitation every year.
Needs a couple more features
I love this radar app and it’s by far the best on the market. I have nothing to complain about, however I do wish there was one added feature that would greatly improve it. I enjoy watching the radar and looking at storms even when they’re not near me, especially tornado warned storms. The only problem is when I see the storms, I can only see the general location of the storm with respect to cities. I wish there was a feature that allowed me to see the precise location of where certain storms are. Even if it was just something where I pressed my finger and it pulled up the latitude and longitude coordinates so I could search them. It would make it a lot more enjoyable for me and would help me to know exactly what houses or businesses are being affected rather than general locations.
Another feature I would like to see is the ability to change the four quick select radars. I would love to have the choice of what four radars I can choose from when holding down on it. I would especially like to see the super res of reflectivity, velocity, specific differential phase, and correlation coefficient. As of right now, unfortunately I am forced to quick select the ones given and have to scroll a lot for the ones I want to see.
