The Leitner system is a powerful spaced repetition method that helps you memorize more effectively by reviewing difficult material more often and mastered items less frequently. Developed by Sebastian Leitner in 1972, it uses a simple box-based flashcard system to strengthen memory and boost long-term retention. This guide explains how the system works, why it’s so effective, and where you can use it online through platforms like Anki, Quizlet, Brainscape, Memrise, and LanGeek.
I discovered LanGeek last year and expected little from a relatively unknown platform, but it turned out to be one of the most impressive tools I have used for learning English. Its multilevel grammar system is the most detailed and well-categorized I have seen, and the huge vocabulary section is perfectly organized with CEFR levels, topics, functions, and test-prep lists. LanGeek also offers over 15,000 original illustrations, a free picture dictionary, a Leitner-style review system, quizzes, custom wordlists, a rich expressions library, and graded reading texts. It focuses on structured, practical learning rather than gamification, making it one of the most underrated English learning platforms of 2025.
I have been using Memrise for a while, and it is one of the best apps I have tried for building and retaining vocabulary. Its spaced repetition system, native speaker videos, and colorful design make learning engaging and effective. However, Memrise lacks grammar explanations, structured lessons, and speaking practice, so it cannot be relied on as a complete language learning solution. It works best as a supplement to other tools like textbooks, tutors, or immersion when aiming for fluency.
I’ve been using Duolingo on and off for years, and while it’s a great tool for building daily learning habits and picking up basic vocabulary, it has clear limits. The gamification kept me consistent, but I realized my speaking skills didn’t improve much despite long streaks. Recent changes, like the AI-driven features and the new linear path, have made the app feel even more restrictive. Duolingo is perfect for beginners or casual learners, but if you’re serious about fluency, you’ll need to combine it with other tools, conversation practice, and structured resources.
