GD is a simple and very useful app to help you remember and learn the words of a foreign language, it allows you to save the words you want to learn and review them when you have some free time for example when you are waiting for a bus or you are on the train so as to memorize them quickly and you are the one who decides which words are most important for you, for example specific words for your job. In addition it also allows you to check your horoscope which in general gives you a simple negative or positive result, obviously the horoscope is not based on scientific data so it should not be taken as a reference for making decisions in your life but look at it as a simple game.
