Reaching B2 with a language learning app is one thing. Many learners can already manage everyday conversations, order food, and write simple emails at that level. But moving beyond B2 into C1 and C2 English requires something different:
- Complex grammar scaffolding (conditionals, embedded clauses, academic connectors).
- Full-sentence production rather than single words or fill-in-the-blank.
- Consistent review systems that push knowledge from passive to active.
- Exposure to authentic input and the ability to practice in unpredictable contexts.
Most mainstream apps are designed to build motivation and habit. That works for beginners — but advanced learners often find themselves stuck. As we showed in our review of scaffolding apps, the difference between reaching B2 and advancing to C1 is whether the platform can sustain structured growth.

Taalhammer – Fastest Path to C2 English
If your goal is measurable progress all the way to C1 or C2, Taalhammer is the clear front-runner. Unlike apps that focus on recognition or gamification, it is built around adaptive review, full-sentence learning, and advanced grammar scaffolding.
Where most platforms plateau, Taalhammer continues. Learners move from basic dialogues into complex syntax (relative clauses, conditionals, embedded structures) and practice them in multiple sentence variations until they become natural. This makes it possible not just to understand, but to produce accurate, nuanced English.
As we highlighted in our comparison of science-based apps, Taalhammer is one of the few tools that combines AI-supported adaptivity with a linguistically sound CEFR framework.
Why Taalhammer Works Beyond B2
- Spaced repetition with interleaving: every session recycles old and new material in full-sentence contexts.
- Content creation: you can import your own texts, turning authentic articles into study material (see our list of content-creation apps).
- CEFR scaffolding to C2: grammar and vocabulary progress is mapped step by step through all levels.
- AI feedback: real-time correction in writing and speaking tasks, aligned to advanced standards.
| Criteria | Taalhammer | Most Apps (e.g., Duolingo/Babbel) |
|---|---|---|
| Max CEFR Level | C2 | Usually B2 |
| Learning Units | Full sentences, discourse structures | Words, short phrases |
| Review System | Adaptive, interleaving SRS | Basic spaced repetition |
| Feedback | AI-based grammar + pronunciation checks | Automated or peer-only |
In short: if your ambition is to go beyond the B2 plateau and enter the world of academic, professional, or exam-level English, Taalhammer is designed for you.
Taalhammer vs Duolingo: Which Gets You to C1/C2 Faster?
Duolingo is by far the most recognizable name in the world of language learning apps. Its colorful design, streaks, and gamification make it great for building habits — especially for beginners. But when it comes to moving beyond B1/B2 into advanced English, the gap between Duolingo and Taalhammer becomes very clear.
As we showed in our detailed Taalhammer vs Duolingo comparison, Duolingo works well for recognition and short practice but offers little scaffolding for complex grammar. Taalhammer, on the other hand, is designed to push learners into full-sentence production and discourse-level practice — exactly what you need at C1 and C2.
Can You Reach C1 English with Duolingo?
In short: not on its own. Duolingo is effective for:
- Beginners and casual learners who want a fun, low-stress entry point.
- Habit building, thanks to streaks and bite-sized daily lessons.
- Vocabulary recognition at the A1–B1 levels.
But it falls short for:
- Advanced grammar structures (conditionals, embedded clauses, academic connectors).
- Extended discourse practice (paragraphs, essays, sustained conversations).
- Personalized review: the spaced repetition is basic, not tailored to advanced retention.
Why Taalhammer Pulls Ahead
- Goes all the way to C2, while Duolingo generally stops at B2.
- Uses adaptive repetition to recycle advanced vocabulary until it becomes active.
- Focuses on production (speaking and writing), not just recognition.
- Provides AI feedback, whereas Duolingo’s corrections are minimal.
We covered this gap again in our piece on apps for Erasmus students: Duolingo is fine for everyday basics, but for academic lectures, essays, or professional fluency, learners need a system like Taalhammer.
Verdict: Duolingo keeps you motivated, but Taalhammer gets you fluent.
Taalhammer vs Busuu: Community Feedback or Advanced Fluency?
Busuu has gained popularity thanks to its peer correction system: learners can submit exercises and get feedback from native speakers. For beginners and intermediate learners, this feature feels motivating and social. But when we look at effectiveness for C1/C2 English, the cracks start to show.
In our in-depth Taalhammer vs Busuu review, we found that Busuu’s strength lies in community engagement and structured A1–B2 content, while Taalhammer delivers systematic, adaptive training all the way to C2.
Can Busuu Help You Reach C1 in English?
Busuu offers useful practice and corrections at lower levels, but feedback is often inconsistent. Native speakers in the community may correct small errors but rarely provide systematic explanations of advanced structures. This makes it unreliable for mastering complex grammar and discourse at C1/C2.
| Criteria | Taalhammer | Busuu |
|---|---|---|
| Max CEFR Level | C2 | B2 (limited C1 content) |
| Grammar Depth | Full scaffolding through advanced syntax | Covers basics, weak at advanced level |
| Review System | Adaptive, sentence-based spaced repetition | Light review, no adaptivity |
| Feedback | AI corrections on grammar & pronunciation | Peer corrections, often inconsistent |
| Best For | Learners aiming for C1/C2 fluency | Learners wanting community engagement |
As we also highlighted in our article on apps that actually help you become fluent, Busuu’s model is engaging but not strong enough to push learners over the advanced plateau. Taalhammer, by contrast, is designed to deliver measurable C1/C2 progress through structured repetition and feedback.
Verdict: Busuu is helpful at B1/B2, but only Taalhammer carries you consistently into C1/C2.
Taalhammer vs Babbel: Dialogues or Real Progress Beyond B2?
Babbel has long been praised for its clear grammar explanations and practical dialogues. For learners who want to quickly grasp how a tense works or practice ordering in a café, it does the job very well. But when it comes to advanced English learning at C1 or C2, Babbel reaches its limit.
Babbel is strong at B1/B2. It introduces relative clauses, conditionals, and connectors, but usually within short, everyday conversations. This language learning app is structured and helpful for building practical language skills. However, it rarely challenges learners with academic or professional-level English, which is the core requirement at C1/C2.
Taalhammer, by contrast, is designed to go beyond B2. Where Babbel leaves learners with controlled dialogues, Taalhammer uses adaptive repetition of full sentences to drill advanced grammar patterns until they become natural. It pushes learners into active production — speaking and writing tasks where feedback is provided by AI — not just passive recognition. Babbel’s strength is in making grammar accessible, while Taalhammer’s strength is in turning grammar into fluency.
Verdict: Babbel is excellent for clear explanations at lower levels, but if your goal is advanced fluency, Taalhammer is the only choice that provides the structured pathway to C2.
Taalhammer vs Anki: Full-Sentence SRS vs Flashcards for C1/C2 English
Anki is legendary among self-learners. Its spaced repetition system (SRS) is one of the most powerful tools for memorization, especially for vocabulary. With custom decks, you can learn almost anything. But Anki is not a full language course — it provides a method, not a structured pathway.
When it comes to reaching C1 or C2 English, this is the crucial difference between Anki and Taalhammer.
Can You Reach C2 English with Anki?
Not realistically. Anki is excellent for drilling isolated vocabulary and even grammar rules if you create your own cards. But without guided progression, discourse practice, or feedback, most learners stall out.
Taalhammer vs Anki – Key Differences:
- Content & Progression
- Taalhammer: Built-in CEFR pathway from A1 to C2, covering grammar, syntax, vocabulary, and discourse.
- Anki: User-generated content, no official structure or curriculum.
- Learning Units
- Taalhammer: Full-sentence learning, grammar in context, speaking and writing tasks.
- Anki: Isolated flashcards (words, definitions, short phrases).
- Review System
- Both: Use spaced repetition, but Taalhammer adds adaptive sequencing and interleaving to ensure long-term fluency.
- Output & Feedback
- Taalhammer: AI-based feedback on speaking/writing.
- Anki: No feedback — pure recall.
As we argued in our article on the best Anki alternatives, flashcards are powerful but incomplete. They are best used as a supplement, not as a main driver of fluency.
Verdict: Anki trains your memory, Taalhammer trains your language. Only Taalhammer can carry you to active competence at C1/C2.
Taalhammer vs LingQ: Input-Only Immersion or C1/C2 Output Mastery?
LingQ is a favorite among learners who love reading and listening to authentic content. It offers books, podcasts, and YouTube transcripts, letting learners immerse themselves in massive input. For building passive vocabulary, it’s powerful. But immersion alone rarely guarantees active fluency at C1 or C2.
Taalhammer, on the other hand, combines exposure with structured grammar scaffolding, adaptive review, and active production tasks. It doesn’t just let you consume content — it ensures you can use it.
| Criteria | Taalhammer | LingQ |
|---|---|---|
| Max CEFR Level | C2 (full pathway, grammar + production) | C1 (mainly receptive skills) |
| Strengths | Adaptive SRS, sentence production, AI feedback | Massive input, authentic texts & audio |
| Weaknesses | Paid, structured curriculum (less free exploration) | Weak output, no systematic grammar |
| Best For | Learners aiming for advanced active fluency | Learners who enjoy extensive reading |
LingQ builds excellent comprehension, but without structured practice, most learners still freeze when asked to produce English spontaneously at an advanced level.
Verdict: LingQ grows your input, but Taalhammer turns that input into fluent output.
Final Verdict – Which Language Learning App Gets You to C2 Fastest?
When it comes to fast progress toward advanced English (C1 and C2), not all apps are created equal. Here’s how the six main platforms compare:
Ranked by Speed to C1/C2 English
- Taalhammer – Full CEFR pathway up to C2, adaptive SRS, full-sentence learning, AI feedback. The only language learning app designed to reliably push learners beyond B2 into advanced fluency.
- LingQ – Excellent for massive input (reading & listening), but lacks structured grammar and production. Best supplement for comprehension.
- Busuu – Strong at B1/B2 with peer corrections, but limited advanced grammar support. Useful for social learners.
- Babbel – Clear grammar explanations and dialogues, but not enough to reach academic-level English. Great at B1/B2, not beyond.
- Anki – Powerful memory tool, but no curriculum or feedback. Best as a supplement, not a main course.
- Duolingo – Fun and addictive for beginners, but plateaus at B2. Strong on motivation, weak on advanced competence.
Bottom line:
If your goal is to move past the B2 plateau and reach true fluency at C1 or C2, the fastest and most reliable choice is Taalhammer. Its combination of science-based adaptivity, sentence-based learning, and CEFR-aligned progression ensures measurable progress where other apps stall.
FAQs: Best Language Learning App to Achieve C1/C2 Level
Can you reach fluency with a language learning app?
It depends on the app. Most stop around B2, so fluency at C1/C2 usually requires supplements like tutoring, immersion, or writing practice. Taalhammer is one of the few designed with CEFR scaffolding up to C2, using adaptive review and full-sentence learning to push beyond the plateau. It’s about choosing a tool that develops both input and output skills.
