It was expected that Japanese developers Librica would release the Bookstore Anywhere app for the 3DS this month, but unfortunately it has been delayed for improvements.
The free app known as Bookstore Anywhere will allow users to read manga and Japanese manga magazines on their Nintendo 3DS. The service is expected to grow to novels and other magazines in the future.
Siliconera reports that the Japanese firm Librica, has announced that the service has been delayed to work on necessary improvements. The app was expected to launch this month, but the company has said a firm release date will be announced "sometime in the future."
At this stage the Bookstore Anywhere app will be for Japan only. A Western release, or a service similar coming to the West remains unknown.
