Developed in partnership with NASA astronomers, APOD for iOS is the official companion app for NASA's Astronomy Picture of the Day project. With over 12 billion daily page views, APOD is one of NASA's most popular websites. The project features the world’s largest collection of astronomy photos.

Since its initial release in 2009, we've ported the app to Android, Windows, Apple TV and the Apple Watch. The apps have been downloaded over 5 million times and have been featured by Apple on several occasions.
