People in need of organizing their lives will soon have one less calendar app to choose from.

The team behind the popular Sunrise Calendar app, which is owned by Microsoft, said on Wednesday that it would shut down the service on August 31 and will no longer support the product. Additionally, Microsoft will remove the Sunrise app from app stores “in the next few days” and users will no longer be able to download it, the Sunrise team explained in a blog post.
