One star.
Dictionary with nice feature
I'm deducting one star because 1) It would be helpful to automatically open the user guide when the app first opens. 2) For Greek, having the article when you learn the word is critical so you know what gender the noun is, and tho the part of speech is given the gender of nouns is not, and that is more important to me. 3) the interface is urilitarian, but not but not outstanding that would rate a 5 for me.
