The impending shutdown was first announced when Apple acquired the company in March of this year. Despite the end of support for the world's most popular mobile operating system, Dark Sky's developers wrote in a blog post announcing the acquisition that joining Apple means they could "reach far more people, with far more impact, than we ever could alone".
The Dark Sky Android app is not the only popular service on the chopping block as a result of the acquisition. Several app developers on both iOS and Android have used Dark Sky's API for weather data for a while now, but like Android support, that's going away.
There's a little more time in that case, though: developers have until the end of next year to find and implement alternative data sources. When the acquisition was first announced, Dark Sky was slated to stop working on Android on July 1. That deadline was extended by one month, but it went into effect as planned on over the weekend.
The Web version of Dark Sky was scheduled to end today, but Apple has extended that deadline, though embeds have been disabled. A new date for the Web shutdown has not been specified. That version will remain an option for Android users for now until it, too, stops working.
