> And sometimes it’s bizarrely off, like saying the UV index is 1 on a cloudless June afternoon. There’s no sanity checking to speak off.

That sounds like weather data that hasn't updated for hours because you have a bad connection or something.

It does drive me nuts that all weather apps I've ever used always show you the previously loaded data, even if it's 5 days stale. I absolutely despise this "optimistic" UX model where it assumes that the most recent data is "good enough" until new data is fetched. Especially since it never even tells you how stale the data is.

Like, if weather data is more than two hours old, I'd rather you show me nothing, because then at least I know to go outside and check, rather than be deceived by the app lying to me.




It happens after multiple refreshes, and it’s just a specific example I chose out of many cases… though it may be possible that the backend server just ignores all that and sends me old data anyways…
