WeatherKit uses high-quality weather data providers like DarkSky, AccuWeather, The Weather Channel and Wunderground alongside a network of other independent weather stations and these providers are sending us monthly invoices for the weather data they provide.
Whenever someone opens WeatherKit on their phone, they get up-to-date weather data from our providers - which we're billed for.
"If it's free, you're the product"
Other companies prefer to violate your privacy and sell your data for advertising purposes, instead of charging for their product, turning yourself into their product. AccuWeather was caught doing it recently and so do others.
The subscription business model allows us to keep working on WeatherKit, turning it better from update to update without compromising your privacy or the product's quality.
