It’s an equivalent app to make a comparison with, one from an OS company.

But yeah, I still remember when a weather app would take 10 MB and I was complaining (1999)

My entire kde "plasmashell" which includes my wallpaper and the various widgets installed (including a weather widget) uses 560MB for a screen with 5120x1440 pixels.

Thank you. And it is a shame I had to scroll down this far in the comments for someone to point out the obvious. Even a weather app that uses "only" 250MB of RAM should never have been delivered by a semi professional software shop - 250MB is enough to store whatever they can display in full screen on a 5k display as a bitmap - 5 times.

I built a weather app for myself fetching ECMWF ensemble forecasts for my home location. Running the service is 60mb plus data 39mb and another 2mb for the spaghetti charts showing temperature, clouds, precip, wind over 10 days. What do I need to do to fill the other 900mb?

The article now says for me "By comparison, Apple's native Weather app on macOS uses roughly five times less memory under similar conditions."... which is not exactly the same wording.

Edit: I see the "250MB" line later in the article. This article is itself bloated for repeating nearly the same thing again.

It is using 122.7 MB at present.

The most lightweight solution I can think of is:
