You’re trying to decide between two language learning apps, and you’ve probably already read three comparison articles that didn’t actually help you choose. They listed features, compared prices, and somehow concluded that “both are great options.”
Not helpful.
Chances are, you’ve already heard of Busuu and Clozemaster, but may not know which one fits your needs best.
What you actually need to know is this:
Busuu and Clozemaster are built for different learners at different stages. Busuu is a structured course designed to guide beginners through grammar, vocabulary, and speaking practice. Clozemaster is a high-volume sentence-based tool designed to rapidly expand vocabulary once you already have basic foundations.
The core difference: Busuu teaches a language step by step. Clozemaster trains vocabulary through massive sentence exposure.
If you know which problem you’re trying to solve, the choice becomes obvious.
Quick Answer: Which Language Learning App Should You Choose?
Choose Busuu if:
- You’re a beginner (A0–A1)
- You want structured lessons and grammar explanations
- You want speaking or writing corrected by native speakers
- You prefer a guided, course-style path
Choose Clozemaster if:
- You already have basic foundations (A2+)
- Vocabulary is your main bottleneck
- You’re learning a less common language
- You’re maintaining or reviving a language you already studied
- You want practice across different levels, as Clozemaster is best for advanced beginners to advanced learners
Can you use both? Yes — and they complement each other well. Busuu provides structure and output practice; Clozemaster provides vocabulary volume.
What Is the Difference Between Clozemaster and Busuu?
The real difference isn’t features — it’s learning philosophy.
Busuu’s Approach
Busuu works like a traditional language course. You progress through lessons aligned with the CEFR framework (A1 to B2), covering grammar, vocabulary, dialogues, and short exercises.
Its standout feature is human feedback. You can submit writing or speaking exercises and receive corrections from native speakers. Busuu also offers a community feature where users can connect with native speakers for practice, making it easy to interact and learn within a supportive community. This is genuinely valuable, especially for learners who want to speak accurately and naturally.
Busuu shines when:
- You want clear structure
- You don’t want to design your own study plan
- You benefit from explanations before practice
You always know what to study next. The app decides for you.
Clozemaster’s Approach
Clozemaster is a retro-themed app that focuses on vocabulary and grammar through cloze tests.
Clozemaster uses cloze deletion — sentences with one word removed that you must fill in. This forces active recall, which research consistently shows leads to stronger long-term retention than passive recognition. Clozemaster uses a cloze test format to help learners fill in missing words in sentences, which aids in vocabulary retention.
In practice, you see a sentence, hear it spoken, and choose or type the missing word. Sentences are organized by word frequency, so you encounter the most common words first and gradually move toward rarer vocabulary. Clozemaster uses sentences sourced from Tatoeba, an open collection of sentences and translations.
Clozemaster offers:
- 50+ different languages and foreign languages
- Thousands of sentences per language
- Frequency lists covering up to 50,000+ words in major languages
Clozemaster offers various modes such as cloze tests, text input, multiple choice, listening exercises, and translation activities. These modes help with learning words, new vocabulary, and new words through fill-in-the-blank exercises, reading comprehension, and translation practice. Using multiple choice questions can provide a less challenging way to learn, while text input requires active production and is more beneficial for retention.
Clozemaster allows users to create custom collections of sentences, known as cloze collections, for targeted practice. Creating custom collections enables learners to focus on specific vocabulary or grammar points. Clozemaster also provides Grammar Challenges to help master difficult grammatical concepts.
Clozemaster is free to use, but offers a premium subscription for additional features. It gamifies language learning by rewarding users with points and fun graphics for completing exercises.
Clozemaster is a high-volume, sentence-based, SRS-driven tool best for intermediate level learners. It is excellent for rapidly building vocabulary, learning in context, and SRS-based review. Language learning apps that incorporate spaced repetition can improve vocabulary retention by reinforcing learned material over time.
Clozemaster focuses on vocabulary and grammar through fill-in-the-blank exercises, and supports reading comprehension, flashcards, examples, and translation exercises to help learners practice vocabulary in context. It is especially useful for learners at the intermediate level who want to expand their vocabulary and grammar knowledge efficiently.
This matters because fluency depends on vocabulary size, and most course-based apps simply don’t provide enough volume.
The trade-off: Clozemaster does not explain grammar up front. You learn patterns by exposure. Some learners love this. Others find it frustrating.
Is Busuu or Clozemaster Better for Beginners?
Busuu is better for complete beginners.
If you don’t yet know how to:
- Conjugate common verbs
- Recognize sentence structure
- Understand basic word order
…then jumping straight into sentence practice will feel overwhelming.
Busuu’s course structure builds foundations gradually and explicitly, which beginners need.
Clozemaster works best after you’ve reached roughly A2 level or completed an introductory course. At that point, grammar is no longer the main problem — vocabulary is. That’s when high-volume sentence practice becomes powerful.
Clozemaster does offer Grammar Challenges, which can help motivated learners target specific structures, but it’s not a full beginner course.
Who Each App Is Actually Built For
Busuu Makes Sense If You:
- Are starting from zero. You need structure before immersion works.
- Want speaking practice with feedback. Busuu’s native-speaker corrections are rare among apps and genuinely useful. Busuu also incorporates videos of native speakers and provides personalized feedback.
- Prefer being guided. You want to open the app, complete today’s lesson, and be done.
- Are learning a major language. Busuu supports about 14 languages, with strong coverage for Spanish, French, German, Japanese, and others.
Busuu is built for learners who value structure and output practice early. The platform has a large community of over 50 million users who practice their languages daily, making it one of the most active language learning communities.
Clozemaster Makes Sense If You:
- Already have basics and want speed
You understand grammar, but vocabulary is slowing you down. - Learn through pattern recognition
You prefer learning by exposure rather than explanations. - Are learning a less common language
Clozemaster supports 50+ languages, including Welsh, Catalan, Latin, Esperanto, and Indonesian. - Are maintaining a language
Perfect for keeping a language active without restarting a beginner course. - Want measurable vocabulary progress
You can track mastery of the most common 1,000, 5,000, or 10,000 words — something courses rarely show clearly.
Language Coverage: Clozemaster vs. Busuu
| Feature | Busuu | Clozemaster |
|---|---|---|
| Total languages | ~14 | 50+ |
| Course structure | CEFR-aligned (A1–B2) | Sentence-based, frequency-driven |
| Less common languages | Limited | Strong |
| Grammar instruction | Explicit lessons | Implicit + optional challenges |
| Vocabulary organization | By lesson/topic | By word frequency |
If you’re learning a less common language, Clozemaster is usually the better option by default. Clozemaster supports a wide variety of different languages and foreign languages—over 50 in total—including many less common options, making it ideal for learners interested in exploring languages beyond the mainstream choices.
Benefits of Learning Languages
Learning a new language is more than just memorizing words and grammar rules—it’s a gateway to new experiences, cultures, and opportunities. For language learners, the journey can sharpen cognitive skills, boost memory, and even delay age-related cognitive decline. In today’s globalized world, being able to communicate in a new language like Spanish, French, or Chinese can open doors to international careers, travel, and friendships.
Thanks to the best language learning apps, it’s never been easier to start learning languages from anywhere. These apps provide instant access to lessons, interactive exercises, and practice opportunities with native speakers. Features like voice recognition help learners perfect their pronunciation, while engaging lessons keep motivation high. Whether you’re interested in learning for personal growth, career advancement, or simply to connect with people from different backgrounds, language learning apps offer a flexible and effective way to build your skills.
By using these tools, learners can practice real-life conversations, expand their vocabulary, and gain the confidence to communicate in their target language. The ability to learn languages online means you can fit practice into your daily routine, making steady progress toward fluency. Ultimately, learning a new language enriches your life, broadens your perspective, and helps you connect with the world.
Using Learning Apps: What to Expect
When you start using language learning apps, you’ll find a variety of features designed to help you build your language skills step by step. Most learning apps offer interactive lessons that cover vocabulary, grammar, and pronunciation, often using short quizzes and exercises to reinforce what you’ve learned. Many apps, such as Duolingo and Babbel, use gamification and repetition to keep you engaged and help you remember new material.
Some apps, like Rosetta Stone and Clozemaster, focus on immersive learning, using real-world scenarios and conversations to teach you how the language is actually used. You’ll often find features like speech recognition, which lets you practice speaking and get instant feedback on your pronunciation. Translation tools and opportunities to interact with native speakers are also common, giving you a chance to practice your target language in a supportive environment.
As you use these apps, you can track your progress, see which areas need more practice, and set goals to keep yourself motivated. Whether you’re working on vocabulary, grammar, or listening skills, language learning apps provide a flexible and effective way to improve. With regular practice, you’ll notice your confidence and comprehension grow, helping you move closer to fluency in your chosen language.
Limitations (Honestly)
Where Busuu Falls Short
- There’s a ceiling
Content ends around B2. Advanced learners will outgrow it. - It can feel slow
If you already know the basics, lessons may feel repetitive. - Smaller language selection
If your language isn’t supported, that’s a hard stop.
Where Clozemaster Falls Short
- No speaking feedback
You need to supplement with conversation or tutoring. - Not beginner-friendly
Some foundation is required. - Self-motivation required
No “course complete” dopamine loop. - Grammar is implicit
You’ll internalize patterns, but explanations are minimal.
Multiple Choice Exercises: A Closer Look
Multiple choice exercises are a staple in many language learning apps, offering a quick and accessible way for learners to check their understanding of vocabulary, grammar, and common phrases. These exercises present a question or sentence with several possible answers, and you select the correct answer from the options provided. This format is great for reinforcing knowledge and building confidence, especially when you’re just starting out.
However, while multiple choice questions are useful, they don’t always challenge you to produce language actively or think deeply about context. That’s why some learning apps, like Clozemaster, go a step further by including cloze exercises—where you fill in the blank with the correct word. This approach encourages you to recall vocabulary and grammar in context, making your practice more meaningful and effective.
Combining multiple choice with text input and context-based questions gives learners a more well-rounded experience. You get the benefit of quick checks for understanding, as well as opportunities to apply your knowledge in more realistic situations. Ultimately, the best language learning apps offer a mix of exercise types, helping you build a deeper, more flexible command of your new language. Whether you’re practicing phrases, grammar, or vocabulary, variety in your practice leads to stronger skills and greater confidence.
Pricing: Clozemaster vs. Busuu
