Almost all weather apps and channels in the US get their raw data from a single government agency called the NOAA. But all of those entities interpret that data and present it to the end user differently. So I can't say how many the average country has, but the US doesn't really have as many as it seems.
I also used Joey, and this is the first time during this whole debacle that I've seen someone else mention Joey in the wild. I was starting to think I was the only one not using Apollo or Sync or RiF.
