tl:DR To use this program you need to buy an Aeris developer licence for $45 a month. The "free developer key" in the description is for 2 months free service, after that you pay. I'm not happy to leave a review like this. The radar feature was invaluable over last summer to warn us of a storm bearing down on us. But this was when "Weather Underground" still offered free developer keys. They phased those out recently. The only other option is "Aeris", and they charge a LOT of money to use their service. $45 a month if I read it correctly. I have a phone app that does this for free. The convinence is outweighed by the cost, so I have to unhappily delete the app from my devices. It sucks, because I really, REALLY liked this one. If someday, down the road, WU or Aeris gets it together and allows us to access radar maps for free or a minimal cost, I'm back on board. But for right now, I can't justify the external cost and I have to give it 1 star for usefulness. Sorry dev, this isn't on you, it's on the service you have us use to use your app. You made a great app, it just sucks that it relies on a 3rd party who tightened the screws.
I understand the frustration with the third parties. With Aeris Weather, it is possible to renew the developer key when it expires at the end of 2 months with your same account and the link in the description. I agree that it is a pain but it does avoid the $45/month cost. I am continuing to look into alternatives but so far, the removal of WU has been a big hit, as i now have to remove it from the app entirely. Leaving me with only the option of Aeris Weather and their 2 month expiring key.
I'm giving it a one Star because it doesn't tell you that it's a paid subscription. It might work but not for 25 dollars a month
If you read the full description, I described how to get the free keys and not require a monthly subscription.
