Here’s a page that lists all the features https://radarscope.zendesk.com/hc/en-us/articles/8991862852754-Upgrading-Your-RadarScope-Experience#Accordion-radarscope-pro-tier-two-2 It doesn’t mention it but I seem to recall that if you don’t have the subscription, you won’t get to use the inspector, distance, and drawing tools but maybe I’m mistaken.

Radarscope is well worth the $10 a year. There’s no fluff, or ads, or any extra crap to bog down the app. Even when I barely have cell service it’ll still work. I like the lightning data also. It’s pretty quick, and I can measure how far it is away. Pretty important to me, and the people around me, when we’re outside. Those are the first several big reasons I’ve been paying for it since it came out. I also like that’s there’s no “future animation” or forecasting. I have other apps for that, all I want is the rawest radar data I can get, plus there’s over 20 different products to look at from the radar. There’s so much data available it can be overwhelming learning them all, but once you get your feet wet you’ll be able to see in real time what’s coming. It’s saved our asses more than once. I’m on the south end of tornado alley, so the weather here can be insane. I’ve only got tier 1, but I pay for it on my phone which allows me to have it on my iPad, and I pay $30 a year for the Mac version as well. There’s a lot more people on the Facebook page. Look for “RadarScope Users Group.” The developers are very active on there, and you can get a lot more questions answered there. More on reddit.com
