Dark Sky augmented their data with user reports and sensor data inside of the phones. There was a time during the summer of 2019 where I was able to impress friends by accurately predicting when rain would start and stop down to the minute based on the rain notifications I would get. When Apple bought them and shut down the Android app they threw away all the data Android users were giving them and Dark Sky became almost exactly the same as every other weather API.
