So, I havent written many reviews on iOS apps, but feel this one is deserving of it. As I study and teach languages Ive found this application to be my constant companion. I love that it can be used on both iPhone, iPod and iPad with the same license and wish there was more integration with the MacOS version. Please bring the MacOS flash card feature to the iOS version and sync the two would be all I can imagine as possible improvements. I feel this is the dictionary standard on which all will be compared and judged. Keep up the great work. I also want to mention the Bookshelf app that unites their various dictionaries is brilliant and something that others can only dream of.
