The built in Apple app is fine for basic information. There are plenty of high-quality third-party apps. Weather Line (my fav) is $2. DarkSky is $4.
Instead people go for these weird free apps covered in ads with terrible UIs. The NOAA one isn’t made by the government, seems like using that name should be some kind of copyright infringement.
Of course WeatherBug on desktops was adware/malware for a very long time. Maybe it still is.
Then you get scareware stuff like the earthquake notification app. You better let us track everything you do otherwise you might die!
There are so many good apps on the store made by good developers. It’s amazing how much better your experience is if you just avoid free apps when possible.
Of course some of these apps, like the ones that you NEED to use for certain parking meters, are especially evil because there is an any choice. If you need that service, you’re giving up your privacy.
I wish Apple would crack down on this stuff. I imagine a lot of these apps are doing things that already violate the App Store guidelines. If they don’t, they probably SHOULD.
