Why grammar-focused learners outgrow Duolingo
Let’s be fair first: Duolingo is genuinely good at what it was designed to do. It gets people to open a language app every single day — which is more than most textbooks ever achieved — and its bite-size, game-like lessons are an excellent on-ramp for beginners and a solid way to build vocabulary. If it got you from zero to “I can read a menu,” it did its job.
The trouble starts when your goal shifts from exposure to fixing specific grammar mistakes. Four design choices work against you at that point:
- Grammar is taught implicitly. Duolingo’s core method is pattern absorption: translate enough sentences and the rules should seep in. That works for word order intuition — but when you get an answer wrong, the app rarely explains why in any depth. You see the correct sentence, tap continue, and move on without knowing which rule you broke.
- The grammar notes exist, but they’re buried. Many courses include short “tips” or guidebook sections. They’re brief, easy to miss entirely, and their depth varies a lot from course to course. Nobody’s daily five minutes naturally routes through them.
- Progression is course-linear. The path decides what you practise next. If your one persistent weakness is prepositions or make vs do, you can’t isolate that rule and hammer it for a week — you get whatever mix the unit serves, with your weak rule appearing occasionally among things you already know.
- Streaks optimise for showing up, not for improving. The streak, the leagues, the reminder owl — all of it is engineered to make you open the app daily. That’s great for habit, but the metric being maximised is attendance. Ten minutes of streak maintenance in a unit you find easy counts the same as ten minutes attacking your worst confusion. Your recurring mistakes can survive a 500-day streak untouched.
The real alternatives, compared honestly
Search results for “apps like Duolingo for grammar” are mostly listicles written by whichever app publishes the blog. Here’s the shorter, more honest version — including where our own app fits and where it doesn’t.
| App | Best for | Grammar explanations | Main catch |
|---|---|---|---|
| Duolingo | Beginners, daily habit, vocabulary | Brief notes, easy to miss | Can’t isolate and drill one rule; streak pressure |
| British Council LearnEnglish Grammar | Free, large question bank | None — right/wrong only | Third-party ads (paid removal); no feedback on why |
| Clozemaster | Post-beginner vocab in context, reading volume | Not its focus | Grammar is absorbed, not explained |
| Promova | Broad structured courses incl. grammar lessons | Yes, lesson-style | Subscription; general course, not a rule-drill tool |
| Engsy | Isolating one rule and drilling it to automatic | Every answer explained | iOS & Android; English only |
British Council LearnEnglish Grammar
Free, from a very credible institution, with a big bank of practice questions sorted by level. The two documented complaints: feedback is strictly right or wrong — you never learn why your answer failed — and the free version shows third-party ads, with a paid option to remove them. If you already know the rules cold and just want volume, it’s a fine free question bank.
Clozemaster
Thousands of fill-in-the-blank sentences that teach vocabulary in context — arguably the best “what next after Duolingo” app for reading volume and post-beginner vocab. But it’s the same implicit philosophy as Duolingo: you absorb grammar from massed sentences. Explaining rules is explicitly not what it’s for.
Promova
A broad course app — vocabulary, speaking practice, and structured grammar lessons — on a subscription. Think of it as a general English course that includes grammar, rather than a grammar tool. If you want one app for everything and don’t mind paying, it’s a reasonable Duolingo-style replacement with more explicit teaching.
What about English Grammar in Use?
Raymond Murphy’s blue book is still the gold standard for explanations, but if you’re looking for its official app: it’s gone. Cambridge removed it from Google Play in October 2022 and it has disappeared from the App Store too. We wrote up what happened and what to use instead.
Engsy — and yes, this is our app
Full disclosure: Engsy is made by us, so read this section knowing that. We built it precisely for the gap described at the top of this page — the learner who has done the courses, knows the rules in theory, and still says “I have been living here since three years” under pressure.
- Organised by rule, not by course level. 60+ short drills across five categories: Common Confusions (in/on/at, make vs do, say vs tell and friends), Grammar, Prepositions, Vocabulary and Phrasal Verbs. You open the exact rule you keep fumbling and drill only that.
- Every answer is explained. Right or wrong, you see the reason immediately — the piece Duolingo and British Council both leave out.
- Three modes take a rule from “understood” to “automatic.” Study mode teaches, Assist mode nudges, Timer mode adds speed pressure so the correct form comes out even when you’re not thinking.
- No guilt mechanics. No streaks, no leagues, no passive-aggressive owl. Practise when you want; nothing resets if you skip a day.
It’s free to start on iPhone and iPad. It is not a full course, doesn’t teach speaking, and won’t replace Duolingo for a total beginner — it’s the drill layer that most course apps are missing.
Which should you pick?
Different problems, different apps:
- You’re a beginner building a daily habit → stay on Duolingo. It’s the best in the world at getting you to show up, and at your stage exposure matters more than rule precision.
- You want reading volume and vocab in context → Clozemaster, especially post-beginner.
- You want a free question bank and don’t need explanations → British Council LearnEnglish Grammar.
- You know the rules but keep making the same mistakes → Engsy. That specific frustration — understanding grammar in theory and fumbling it in speech — is its whole reason to exist. We’ve written about why known rules still come out wrong and what fixes it.
- You’re preparing for an exam → grammar accuracy is scored directly in IELTS writing and speaking; see our guide to grammar practice apps for IELTS.
Quick answers
Does Duolingo actually teach grammar?
Partly. It teaches grammar implicitly through pattern repetition, and most courses have short grammar notes. But feedback rarely explains errors in depth, the notes are easy to miss, and the linear path won’t let you isolate a weak rule. Good for intuition; weak for fixing a specific recurring mistake.
What’s the best app to drill one specific grammar rule?
One organised by rule rather than by course level. Engsy’s drills are sorted by exactly the confusions learners search for — in/on/at, make vs do, say vs tell, gerund vs infinitive — with an explanation on every answer, so you can hammer one rule until it’s automatic.
Is there a grammar app without streaks?
Yes. Engsy deliberately has no streaks or leagues — practice is there when you want it, and skipping a day costs you nothing. British Council LearnEnglish Grammar is also streak-free, but gives no explanations with its answers.
Should I quit Duolingo entirely?
Only if it’s stopped serving you. For habit and vocabulary it remains excellent; the honest move for most grammar-focused learners is to keep it for exposure and add a dedicated drill tool for the mistakes it doesn’t fix.
