Project 2025 wants to disband NOAA and give its functions to Accuweather instead, directing taxpayer funding to a private company while also locking all weather data behind a paywall, so they get paid twice to provide the same info NOAA currently provides with a single payment (taxpayer funding). The Accuweather founder, Joel Myers, and his brother, Billy Lee Myers (unsuccessfully nominated by Trump to be the head of NOAA), are major Republican donors, but I’m sure that is completely coincidental.
I don’t know about apps, but they ultimately all get it from the National Weather Service. Since it’s a government service, the website is totally free of ads and other garbage. Just use that. Weather.gov. You can search for your home, and since it uses absolute URLs, you can then bookmark the results page and just go straight to that every time.
