Ultra-short-range weather on Apple devices uses what used to be called "Dark Sky", before Apple bought it. It's how you get those alerts that say things like "Light rain in 17 minutes".
Dark Sky was just the name of a weather app that included that feature earlier than Apple's weather app.
But things like "rain in X mins" is a feature multiple providers & apps have (including Apple once they bought Dark Sky), it's not specifically what Dark Sky was nor is it exclusive to them/Apple. (And actually, Dark Sky was probably the best weather app all round, yet Apple despite buying them and using some of their tech still produce one of the worst weather apps in my experience.)
Hi, if you miss the Dark Sky, I am running a privacy-conscious indie weather app that can be configured to look just like the Dark Sky app: https://weathergraph.app
