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 use Dashlane, but I don’t see anyone else mentioning it. Why do you want to change? Is there something wrong with it?
