Join thousands of students and memorize words, sentences, expressions and grammar rules in a simple and intuitive way! Memhack is an app that uses a powerful SRS (spaced repetition system) algorithm to help you fix content: no more forgetting everything within days after you study! All the flashcards were created by teachers in order to guarantee the best learning experience possible in any language! It works in a very simple way: during your Fluency Academy classes, you will learn a lot of new words and expressions, and after class you’ll be able to practice them all by using Memhack! Reinforce the content seen in class through an algorithm that is personalized for you: the app learns with your answers and shows the cards you need to review at the right moment. Don’t waste hours and hours planning and creating cards or lists from scratch - our team of teachers has already done that for you! This way, you can focus on what really matters: learning. To make your learning even easier, we created an intuitive and user-friendly interface, all you have to do is open the app and study! All your progress is synced with the web app, which means you can study on both your computer or smartphone. So hey, let’s revolutionize your way of learning languages?
