WordList for Android
The main idea is to help people to build their own dictionaries and then to learn the words by asking them.
Let's say, for example, that you are learning italian and spanish. You can create two lists, one for each language, and add the words you need to learn. You will be able to search for a word's meaning whenever you want or learning by playing the classical quiz game.
Easy to use. Just create your lists and memorize them wherever you want.
