Developer renamed this app to 'RadarScope 4' from the originally named 'RadarScope', then released a new app with the same name as before. But yeah now you have to re-buy the app with no consideration of prior purchases of the same app as before. I have reported the developer to Apple for review of a store policy violation!

RadarScope is the perfect weather radar app. You can view many parameters in detail for one radar site. It is a great app for weather professionals. If you want to see the entire country's weather radar sites at one time, get a different app. That is not RadarScope's specialty. No other weather app I've seen will show as much detail as RadarScope.

I primarily use RadarScope on iOS (iPad and iPhone). I have used it for years, and use it to navigate around storms, predict arrival and duration of storms. Before, the annual pro subscription tier 2 for iOS worked on the Mac too. This no longer works, as others have reported. Canceled my pro subscription. This was a great app, but I understand it appears DTN, no longer has the staff to support the app. Oh well....

It used to, which is why I gave it the extra star. I am a Pro Tier Two subscriber but whenever I try to "restore" the purchase on my imac I get an error saying the application is damaged, delete it and restore from the apple store. - rinse repeat etc.

Apparently you do not share a sub for pro between iOS and MacOS. Too bad.

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.

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.

Pay for a subscription for the iOS versiona and it not carry over to this app on the mac. really a horrible business model.

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.

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.
