Carrot Weather vs the native app?

Hello,
I love weather! 18 years ago, for my birthday, I went to my local news station & got to predict the weather for that particular night.
You know what? My predictions were 100% accurate & they were purely guesses.
I'm writing to you today, to ask if anyone here can give a good comparison of the native weather app & Carrot weather.
At one point, I was subscribed to Carrot weather premium, but had to cancel for various reasons, a few years ago.
In the time that has passed, the app has dramatically changed. So much so, that I no longer know how to use the iPad version. I didn’t realize how much information CARROT Weather had. I clicked on something that included the abbreviation MB, and it started telling me about pressure. I copied that entire message to my clipboard, for later review.
Any assistance you fantastic people can provide, is greatly appreciated.
