"504 Essential Words" is an application that aims to teach English in a fun and interesting way. This app is developed by a team of professional educators who have many years of experience in teaching English to adults and children.

We have divided the lessons into three parts: Vocabulary, Grammar, and Conversations.

In the Vocabulary section, we aim to teach you the vocabulary that is needed in order to learn the basics of the language. This is the most important part, because it is the foundation for all the other parts. We use a very efficient method to learn vocabulary, which is one of the most effective methods for learning any language.

In the Grammar section, we aim to teach you the structure of the English language, in order to understand how it works and how to use it properly.
