Best English Vocabulary Apps: 8 Apps Ranked for 2026

How to Choose the Right Vocabulary App

English vocabulary apps range from gamified daily lessons to hardcore spaced repetition systems. Some focus on authentic native speaker video, others on AI pronunciation feedback. The right choice depends on how much time you have, your budget, and whether you want a structured course or a flexible flashcard system.

We compared eight apps that cover the full spectrum. Duolingo and Memrise are great for building a daily habit. Anki and Quizlet give you complete control over custom content. Elsa Speak combines vocabulary with pronunciation coaching. Busuu embeds vocabulary in a full CEFR course. Preply connects you with a real tutor for personalised instruction. Drops focuses on quick visual sessions.

We compared them across six categories: price, learning method, vocabulary size, level range, free options, and best use case. Use the comparison table to see the full picture, then read the detailed reviews to find your best match.

Comparison Table

1. Memrise

Memrise combines spaced repetition with short video clips of native speakers using words in real contexts. This is one of the most effective ways to build vocabulary because you hear how words actually sound in conversation.

The free version gives you access to thousands of words across multiple levels. Pro costs $14.99 per month and adds grammar lessons, listening skills, and offline access. Memrise covers around 5,000 words across beginner to intermediate topics.

The main downside is limited advanced content. Upper-intermediate and advanced learners may need to supplement with another tool.

2. Duolingo

Duolingo is the most popular language app in the world. It uses gamified lessons with points, streaks, and leaderboards to keep you motivated. Vocabulary is introduced through themed units covering 3,000+ words.

The app is free with ads. Super Duolingo costs $6.99 per month and removes ads, gives unlimited hearts, and adds personalised review sessions. Duolingo is excellent for building a daily habit, but vocabulary depth is limited compared to dedicated tools like Anki.

Best for casual learners who want consistent, low-pressure vocabulary practice.

3. Anki

Anki is a powerful spaced repetition flashcard system. You create your own decks or download shared decks from thousands of categories. The customisation is unparalleled. You control review frequency, card format, media, and scheduling.

The desktop and Android app are free. The iOS app costs $24.99 one-time. Anki has a steep learning curve. You need to invest time in creating or finding good decks. But for serious learners, it is the most effective vocabulary tool available.

Best for advanced learners and students who want complete control over their vocabulary study.

4. Quizlet

Quizlet is a flashcard and study game platform. Users create and share millions of vocabulary sets for every topic. Study modes include flashcards, learn, test, match, and gravity game.

The free version covers basic study modes. Plus costs $35.99 per year and adds image uploading, offline access, and ad-free study. Quizlet is excellent for memorising specific word lists for exams or courses. It does not use true SRS scheduling like Anki.

Best for students who need to learn specific vocabulary sets for tests or courses.

5. Elsa Speak

Elsa Speak uses AI speech recognition to improve your pronunciation while teaching vocabulary. You practise saying words and the app gives instant feedback on accuracy, stress, and intonation.

The free version includes limited lessons. Pro costs $11.99 per month and unlocks the full library of 2,000+ vocabulary words and 200+ speaking topics. Elsa Speak is unique in combining vocabulary with pronunciation coaching. The vocabulary range is smaller than Memrise or Anki.

Best for learners who want to improve pronunciation while building vocabulary.

6. Busuu

Busuu teaches vocabulary as part of a full CEFR-structured English course. Each level introduces relevant vocabulary organised by theme and grammar topic. The app uses spaced repetition for review.

Premium costs $13.99 per month and gives access to all CEFR levels A1 to B2, around 3,500 vocabulary words. Busuu also connects you with native speakers for feedback on your speaking exercises. The vocabulary is embedded in a structured curriculum, so you progress naturally through levels.

Best for learners who want vocabulary within a structured, progress-tracking course. Try Busuu free.

7. Preply

Preply is not a vocabulary app. It is a tutoring marketplace where you can find 1-on-1 English tutors who focus on vocabulary building. Lessons cost $5 to $30 per hour depending on the tutor.

The advantage of Preply is personalisation. A tutor can target your weak areas, teach vocabulary relevant to your goals (business, travel, exam prep), and give real-time corrections. The downside is cost. It is more expensive than self-study apps.

Best for learners who want personalised vocabulary instruction from a human tutor. Find a Preply tutor.

8. Drops

Drops focuses exclusively on vocabulary through visual learning. Each word is paired with an illustration, and you tap, swipe, and match your way through 5-minute sessions. The time limit keeps sessions short and focused.

The free version gives 5 minutes per day. Premium costs $13 per month for unlimited sessions and full topic access. Drops covers around 2,500 words across 100+ categories. It is a good supplement for visual learners but lacks grammar, speaking, and listening practice.

Best for busy learners who want very short, visual vocabulary sessions.
