There is a new app for Android (AndroidZoom Preview
) by a Greek online bookstore, myeBooks.gr, and I think it might be interesting for you. Apart from integrating their own bookstore with Greek e-books, what is interesting from an international perspective is that the app has a menu in English and supports ebooks in ePUB or PDF format from any bookstore using Adobe DRM (apart from B&N that is), also ebooks of the same format without any DRM (e.g. a personal document). In-app purchase is possible only from their bookstore, but, apart from that, it is quite close to Aldiko 2.0 app. They were released the same day. The app is free.
I had the opportunity to use their app shortly before being officially released and a have taken some screenshots
. A iOS version awaits approval from Apple.
