From Helma Dik via the Digital Classicist List:
I'm delighted to announce the release of an iPad app for introductory and intermediate Greek readers. Its name is Attikos and it includes a selection of familiar texts, including morphological information. The author is Josh Day, himself recently an intermediate Greek student.

Writing the app would not have been nearly as feasible without the Perseus Project's generous policies of making its data available to third parties. It includes links to logeion.uchicago.edu, which is an interface for dictionaries and reference works, including Liddell and Scott. Again, that website is based for the most part on resources from the Perseus Project at Tufts. When not connected to the internet, the app itself offers short definitions, as familiar from Perseus.
Texts include the Iliad, some Lysias and Plato, and the Antigone. Some texts have been parsed completely; no translations are included, however. Bonus features allow the user to look up morphological parses of words they type in, or figure them out with the included morphological charts.
