Yes! The ability to be outside, pull out your phone, and get an almost-to-the-minute awareness of when it was going to rain felt magical, right out of Back to the Future 2. I used this countless times.
So much of weather forecasting, at that time, was about trends and probabilities. DarkSky was about events, certainty, and action.
It was truly ahead of anything else and forced a new standard.

But iOS has this now. It's the same thing. They integrated it from Dark Sky.
