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.

  • No sub across devices

    By AndyPu
    Apparently you do not share a sub for pro between iOS and MacOS. Too bad.
  • Awesome app but pricing is wack

    By weskarl
    This is a world class radar app with one big caveat. The good: if you are familiar with the iOS app, expect similar (at a much higher price), with the ability to scale to your resolution of choice. The bad: reoccurring subscriptions purchased on iOS do not transfer over to the Mac App, and initial buy in is @ 3x.
  • Excellent Program

    By gtdandy
    I've been using the iOS version of this software since the very beginning. I also use an app that shows a national radar map and temperatures and such, but when I want to examine what's happening at a local level, there is nothing that beats this program, in my opinion. I admit that a lot of the information presented is kind of technical, but as an weather fan it has been worth reading their help and learning about these things. I recently updated from the Pro1 tier ($10/yr) to the Pro2 tier ($100/yr) and have found it well worth it for all the new data and graphics to learn about.
  • Bad Subscription Policies

    By dohspc
    Pay for a subscription for the iOS versiona and it not carry over to this app on the mac. really a horrible business model.
  • Over priced and exploitative subscription pricing vs. iOS

    By resker
    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.
  • Best Mac radar app by a long ways!

    By JLJD
    Ive tried so many different radar apps for the mac and have always been disappointed. Not anymore. RadarScope is fantastic on the phone and now its even better on the Mac - especially with the very inexpensive Level 1 pro subscription. I dont understand anyone giving this app anytihng but 5 or 4 stars.
  • Outstanding App

    By KernelPanic15
    There is nothign else like this for the Mac. Whether you are a weather enthusiast or a die hard storm chaser, this is THE app to have. Its tightly focused on ONE radar at a time. Its not designed to provide mosaic views of multiple radars , a function some reviewers dont seem to understand. The developer provides outstanding support and is open to suggestions and bug reports. By far thi is the best app Ive ever purchaed!
  • Will not validate

    By PropFlier
    I subscribe to Tier 1 in itunes. I paid $29.99 for the Mac version and it will not restore my subscription. It is telling me that my "radarscope.app" is damaged; for me to delete and reinstall, which I did. Still broken and will not validate. All this during a severe weather event...
  • Works for me

    By Whisperkey
    Works for me
  • No radar any longer

    By Al32401
    This was a great app with current weather, weekly forecast, and local and US radar pictures. But the radar is no longer functional.
