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 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, Puerto Rico, Korea, and Okinawa, as well as reflectivity and velocity data from Environment Canada 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 NEXRAD weather radar on your iOS device and Apple Watch. When there are any Tornado Warnings (outlined in RED), Severe Thunderstorm Warnings (YELLOW polygons), Flash Flood Warnings (GREEN polygons), or Special Marine Warnings (ORANGE 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, 30 other radar sites in Canada, and 2 in the Republic of Korea. 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 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 auto-renewing subscription with two different tiers to choose from. Super-res products are still available to all RadarScope users without purchasing a subscription. RadarScope Pro Tier 1 is an annual subscription that provides access to real-time lightning data that animates along with the radar loop and up to 30 frames of radar data, including *extended loops* of Super-Res Level 2 data. Tier 1 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 2 is an annual or monthly subscription that combines all the features in Tier 1 with more advanced features, including SPC outlooks, local storm reports, a 30-day archive of all radar products, estimated hail size contours, rotation (azimuthal shear) contours, and the ability to use subscription features across multiple platforms. RadarScope Pro subscriptions are charged to your App Store account. It 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.

  • Wonderful

    By Flexoffset
    Excellent. Only tiny gripe is that the map is too simplistic. Would love an option to increase detail on the map.
  • 4.5 Really

    By Mesocyclone
    I would really like to see watch boxes, a composite view of the U. S. And the ability to to toggle the information to make it 5 stars for $100
  • Please add CarPlay ‼️

    By Suddenrush
    It would be awesome to display the data from the nearest radar in CarPlay. Great for solo storm chasers and people that want to avoid a storm along their route. Now you can!
  • Best app for pro and amateur weather enthusiasts. Hand down.

    By Breakbeatman1234589
    Five stars is not enough! RadarScope is not only my absolute favorite weather-related app but is solidly one of my top-five overall favorite apps of all time—one of those rare “It’s so good it’s worth buying an iPad just to use it” apps. I found out about RadarScope from watching livestreams of professional storm chasers using it. I figured if it’s good enough for the folks who rely on it to navigate life-or-death situations where small errors could have catastrophic consequences, then it must be one amazing app. Boy, was I right. Yes, this one has a steep learning curve if you’re an untrained, amateur meteorology enthusiast such as myself (I assume if you had a a solid meteorology background, this app would be a piece of cake to use). However, it’s totally worth the investment if you’re looking to step up your weather game. To get full use of it as a non-professional make sure you throughly read the “Radar Products” section in the user guide (and perhaps even outside sources to flesh out the details) to make sure you understand what your looking at (and in that sense, this app also is hands-down the best meteorology education tool on the market). The warnings from the other raters bear repeating here: if you don’t have the knowledge to get the most out of this and aren’t willing to take the time to learn, or if you’re just looking for a basic weather summary to know whether to take a jacket or if your tee time will get rained out, or even if you’re just looking for a basic weather radar, then this app is most definitely NOT the app for you. Also, note that data is provided mainly for the United States.
  • Great app but unethical

    By Landy Family
    I was surprised to read an article to where this app sells our information and all of the phones info to data monetization companies. It’s alarming that Apple allows this to be done.
  • Unavailable

    Says radar is unavailable...for the past week. Can I have a refund?
  • Perfect in Almost Every Way

    By A320Freak
    I bought this app long ago, back before the 2013 Moore EF-5. It has served me so well since then. And new features keep getting added, making this app basically a portable AWIPS workstation, minus WarnGen. There’s one thing that I’d love to see added, though, and that’s the ability to set our own storm motion vectors and have velocity products calibrated to that. For people who use RadarScope for chasing, that would make it so much easier. Other than that, this app does wonders for storm chasers who are looking for quick and easy access to site specific radar products. Oh, and the app will snap to the closest radar if you enable location. Even without custom SRV, this app gets five stars for its simplicity to use and the tools that can be had with the subscriptions.
  • Best weather app, period.

    By roadwarrior775226
    The accuracy is amazing. The refresh rate is much better than any other app. Even just going to the beach you can tell down to a few feet if you are going to get rained on or not. Saved the day today!
  • Awesome professional app

    By Ole Blue Express (Mark)
    First saw this app being used on a Birmingham Alabama TV station during the super outbreak of tornadoes a few years ago. I was hooked and purchased it the same day. Each update is pure thought and usefulness. RS is my first go to app in the event of any weather event. The ability to control the radar's tilt and product is spectacular. 100% recommend well worth the money!
  • Professional grade radar and storm tracking! 💯

    By NateDawg1123
    This is the de facto standard app for radar and storm tracking data. Ask any storm chaser. Yes it costs money, but is so worth the cost for the features you get. I subscribe to the Level 2 data and it is perfect for my needs. High resolution reflectivity and lightning data is great to have. Refresh rates are nice and disable auto lock is handy when a huge storm is passing over. Forget the haters, probably people that don’t really understand what they are getting. This app is the real deal! 👍🏻
