Hyperlocal forecasting, who just ejected most of the world from their data collection pool.
IIRC they built the models with user data, but stopped collecting from phones because so many different sensors are used for rH and temp in phones plus being in pockets, battery temp, etc meant the data had too much variance. Even though I hate that they did this bc it's my favourite weather app, it actually would make sense to just use iphones if they were going to start collecting that data again since all the hard…
I work on a related app to do that barometer data on Android: https://play.google.com/store/apps/details?id=com.allclearwe... (US only for now).
