DarkSky

Dark Sky was a weather data company and consumer app known for its hyperlocal forecasts and a widely used developer API. The service offered a mobile app that delivered precise, minute-by-minute precipitation forecasts and weather alerts, along with a web API that allowed developers to fetch current conditions, hourly forecasts, daily forecasts, and specialized data such as rain probability and precipitation intensity. The API supported integration into apps, widgets, and websites, enabling high-resolution weather information to be embedded in third-party products.

In addition to the API, Dark Sky provided data and forecasting features designed to deliver down-to-the-minute insight for a given location, as well as tools for developers to customize how weather information was presented in their applications. The emphasis on hyperlocal, timely data helped it gain widespread adoption among both consumers and developers.

Dark Sky was acquired by Apple, and its technology and data were integrated into Apple’s weather offerings. Apple announced the discontinuation of the Dark Sky API and the retirement of the standalone Dark Sky app, with ongoing access and branding transitioning to Apple’s own Weather services. As a result, the Dark Sky API and related consumer apps are no longer offered as independent products, and the underlying data and technology have been folded into Apple’s broader weather platform.

Today, the Dark Sky legacy is remembered for popularizing precise, location-based weather forecasting and for providing a widely used API that influenced subsequent weather-data services.
