You might find the Apple weather app is often incorrect. Plenty of other options. Personally I’ve been using carrot weather.
Apple
A place for Apple news, rumors, and discussions.
I've been using Carrot too, mostly because of the snarky comments and the ability to pick your weather source. I've pretty much just accepted at this point that every weather app is going to be extremely wrong at some point lol
Keep in mind that you are not locked into the apple ecosystem for a lot of things. So if you’re used to working with Google drive or Dropbox, there are apps for that on iOS as well. Personally I’m using Instapaper instead of Safari’s “reading list” feature because it works across multiple devices and operating systems.
There’s also an iCloud app for Windows and a web-based interface for iCloud if you ever need to access your stuff there on a non-Apple device.
I like copilot for finance tracking.
Carrot is a solid weather app, flighty for flight tracking. I heard Halide is nice for photography.
Grab the shortcuts app for some awesome automation things.
Shortcut seems really, really interesting
