Released ahead of the property's cinematic debut, the app includes access to more than 200 digital comics, the latest trailers for the film, and other promo materials.
Other featured sections include a beginner's guide to the character, a comic store locator, and previews of Green Lantern releases in other media, such as the video game Rise Of The Manhunters and the animated feature Emerald Knights.
Like DC's official iOS app, which was launched in conjunction with comiXology last year, the programme features guided view technology for panel-to-panel browsing.
Directed by Martin Campbell, Green Lantern stars Ryan Reynolds, Blake Lively, Mark Strong, Michael Clarke Duncan, Peter Sarsgaard and Angela Bassett. The film arrives in theatres on June 17.
The Green Lantern app is compatible with iPhone and iPad devices. It is available to download through the App Store.
