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 and Special Marine 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 and Australian Bureau of Meteorology 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, and special marine 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.
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 289 different radars in the United States, Canada, Australia, Korea, Puerto Rico, Guam, or Okinawa. 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 recent 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 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. Spotter Network members can report their location and view the locations of other spotters.
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 a data interrogation tool to quickly determine data values for specific radar pixels and an optional dual-pane mode for viewing two 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, 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.

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.
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.
No radar app can hold a candle to this one
I have been a weather nerd since I was a little kid, and I’m a trained Skywarn Storm Spotter. I first downloaded this app in 2013 when a meteorologist mentioned it after I was complaining about how I struggled to find a decent one. Most radar apps have a smoothing algorithm that obliterates storm structure. This app does a beautiful job with with its radar display. I’ve struggled to find certain details like specific rotation data inside a supercell storm, the correlation coefficient to detect tornado debris, decent hurricane reflectivity to see structure of the rain bands as well as the rotation within (I live in Florida), or just basic resolution to see what part of the storm will hit my location. This app does it all and so much more that I could write a book on it. The features of data are endless. I’ve used it through Hurricane Matthew, Irma, and Dorian (and plenty of other tropical storms). The storm season here has me tracking several hundred storms over the years. I have it on my MacBook Pro and my iPhone. There’s a reason all the professionals, scientists, and storm chasers use this app. It’s the best $10 I’ve ever spent.
