I love being able to go back and forth between different languages, having multiple games, and the audio function which allows you to listen to words and their translations while doing something else. Unfortunately, the apps current limitations make it largely useless for my purposes. The biggest problem is that you cannot select the words to be use in the games to review those you are learning (favorites) or even a single category of words. You just get random words that you probably have never seen before and may never see again (if you are a beginner). The audio function does allow this, which is great, but I can only get it to repeat 5 words over and over, rather than moving on to new words. You get one list of favorites, rather than being able to review your favorites within each category. Finally, less importantly , but still a small annoyance, the search function works well, but doesn’t allow you to add the word directly to favorites. The selection of words and phrases is quite good though, more useful than many more expensive apps for some languages (like Greek) plies the games add some nice variety, so I hope they add in a bit more flexibility so that it is more practical for language learners.
