This is an excellent quick reference guide. It is definitely worth the money to buy this app, and upgrade from the free dictionary version.
I would also be willing to pay more for additional features, such as more audio examples, and some lessons to work through with audio examples. People pay hundreds of dollars for language learning software ( Rosetta
Stone ) so why not spend some time and so something similar for the iPhone and iPad ? I would buy it.
