Some of us plan to learn a new language whenever we want because, for them, it is such an advantage especially if they are fond of traveling. If they want to try learning German, they might want to try this app and learn without any hassle.
The German English Dictionary app provides vocabulary quizzes to test if you really learned something. It has 20 categories for Phrasebook so you can choose which one you want to focus on first, whether it is Conversation, Asking Directions, and Making Friends.
One of the best features of this app is that you can use it whenever and wherever because this can still be accessed even if you are offline.
