7 English grammar learning apps to consider in 2026
1. LearnEnglish Grammar by the British Council
Best for: learners who want grammar practice rather than a general language-learning app.
LearnEnglish Grammar is built specifically around English grammar accuracy. The British Council currently describes practice from beginner through advanced levels, with more than 1,000 practice questions across multiple activity types and grammar topics. The app also includes practice and test modes, making it useful when you want to identify weak areas and repeat them.
Why choose it: It is one of the clearest options in this list if grammar itself is your main goal.
Availability: iPhone and iPad, with Android availability through the British Council’s current app listings.

2. Duolingo
Best for: building a daily learning habit while developing grammar, vocabulary, reading, listening and speaking skills.
Duolingo is broader than a grammar-only app. Its current English courses combine grammar and vocabulary with listening and speaking activities. Duolingo also provides personalised explanations for mistakes through its Explain My Answer feature, which it made available to all learners rather than keeping it only for subscribers. Its newer course design also uses shorter intermediate mini-units with more frequent opportunities to apply new grammar and vocabulary.
Why choose it: It works well when grammar is one part of a wider English-learning routine.
3. Busuu
Best for: students who want a more structured course with dedicated grammar review.
Busuu’s English course is aligned to CEFR levels from A1 through C1. Its Grammar Review area lets learners revisit grammar topics from the Complete English course and practise specific topics or use personalised practice. In 2026, Busuu also offers Mistake Repair on iOS for eligible English learners, turning previous mistakes into targeted grammar exercises.
Why choose it: The combination of structured lessons, grammar review and targeted practice makes it useful for learners who want more than isolated quizzes.

4. Babbel
Best for: learners who want grammar taught in the context of practical language use.
Babbel combines short lessons with vocabulary, grammar, listening and speaking practice. Its current app includes a Practice area with grammar activities, and Babbel provides a Grammar Guide with concise explanations and examples for supported beginner-level courses. Babbel also offers AI-supported conversation practice in its Babbel Speak feature for selected language combinations.
Why choose it: It is a stronger fit for students who want grammar connected to conversations and real-world communication rather than grammar drills alone.
5. Merriam-Webster Dictionary
Best for: checking how words are used while reading or writing.
A dictionary is not a substitute for a structured grammar course, but it can be an important companion. Merriam-Webster’s mobile experience provides definitions, example sentences, pronunciation and thesaurus-style reference features. Use it when you encounter an unfamiliar word, want to check usage, or need to compare related terms while writing.
Why choose it: It complements a grammar-learning app by helping you understand vocabulary and usage in context.
6. Cambridge Dictionary +Plus
Best for: grammar quizzes, vocabulary practice and reliable learner-dictionary reference.
Cambridge Dictionary +Plus provides free word lists and quizzes, including dedicated grammar quizzes. Cambridge’s learner dictionaries are also designed for English learners at different levels, making the service useful when you need both a grammar check and a better understanding of a word’s meaning or usage.
Why choose it: It is particularly useful as a reference and practice companion for students preparing for English-language study or exams.

7. Johnny Grammar’s Word Challenge
Best for: short, game-like grammar practice.
Johnny Grammar’s Word Challenge is a British Council quiz app covering grammar, vocabulary and spelling. It uses three difficulty levels and includes common grammar topics such as prepositions, irregular verbs and conjunctions. Each answer also provides feedback, which makes it more useful than simply guessing answers and moving on.
Why choose it: It is a good option when you have only a few minutes and want focused practice rather than a full lesson.

How to choose the right grammar app
- Need grammar drills? Start with LearnEnglish Grammar or Johnny Grammar’s Word Challenge.
- Need a complete learning routine? Consider Duolingo, Busuu or Babbel.
- Need help while writing? Keep a dictionary/reference app such as Merriam-Webster or Cambridge Dictionary +Plus available.
- Preparing for an exam? Look for CEFR-aligned material, practice tests and the exact exam syllabus rather than assuming any popular app covers every required topic.
- Learning on a budget? Check what is actually included in the free tier before choosing an app. Free downloads do not always mean that the full course is free.
- Using AI features? Treat generated explanations as learning support, not as an unquestionable authority. Verify confusing grammar rules with a trusted reference or teacher.
A simple way to use grammar apps effectively
- Choose one primary learning app instead of installing ten apps and using none consistently.
- Study one grammar topic at a time, such as verb tenses, articles, prepositions or conditionals.
- Write a few original sentences using the rule. Recognition exercises alone are not enough if you need to write or speak accurately.
- Review mistakes after a day or two instead of immediately moving to a new topic.
- Use a dictionary or grammar reference when you encounter an exception or an explanation you do not understand.
- Practise speaking and writing alongside app exercises. Grammar knowledge becomes useful when you can apply it in real communication.
Are grammar apps enough to learn English?
Usually, no. An app can make practice convenient and consistent, but strong English skills require more than answering multiple-choice questions. Combine grammar exercises with reading, listening, writing and speaking. If you are preparing for an exam or need English for academic or professional work, use the app as one part of a broader study plan.
Final recommendation
If grammar is your main weakness, LearnEnglish Grammar is a sensible starting point because it focuses directly on grammar practice. If you want a broader daily learning experience, compare Duolingo, Busuu and Babbel. Keep Cambridge Dictionary +Plus or Merriam-Webster as reference tools, and use Johnny Grammar’s Word Challenge when you want quick practice.
The best app is the one that matches your level, goal, budget and study habits. Check the current app-store listing and privacy information before installing, because features, pricing and platform support can change.
