In a simple way, you will create your own sets of flashcards. The sets will be tailored to your needs, allowing you to learn only the useful words and phrases from your surroundings or industry. You create the flashcards yourself, so you will only learn the words that are helpful to you, and you will not waste time on unnecessary words that you will never use. You will have the option to listen to every word with a narrator, which will help you learn the correct pronunciation. You can create flashcards vocally using the built-in translator, allowing you to learn while playing games, watching shows, or going for a walk.
