Babbel vs Duolingo: Languages offered

Babbel prioritizes depth over breadth, focusing on 14 popular and in-demand languages like English, Spanish, French, German, and Italian. Its courses are meticulously crafted by language experts, ensuring a strong foundation in each language.

Duolingo, on the other hand, boasts a vast and ever-expanding list of languages (40 languages, as of writing), including some less common options like Hawaiian and Navajo and conlangs like Klingon and High Valyrian (Game of Thrones fans rejoice!). This variety is great for those with a more niche interest and those who want to switch between languages quickly. But not all of its courses are created equal, with some more developed than others.   

Ultimately, the choice depends on your goals. If you’re serious about achieving fluency in a popular language, Babbel’s focused selection might be ideal. But if you’re curious about a more unique language or simply want to dabble in a few different tongues, Duolingo’s diverse offerings could be more appealing.

Babbel’s learning methods and course structure

Babbel takes a structured approach to language learning, designed to build a strong foundation in all core skills: grammar, vocabulary, listening, and speaking. The main goal, however, is to help you become conversational as quickly as possible.

Babbel achieves this by focusing on real-world scenarios and practical dialogues. The courses break down complex concepts into manageable bite-sized chunks. New vocabulary and grammar structures are introduced in small groups of words or phrases, accompanied by native-speaker pronunciations and clear illustrations.

Because the goal is to get you speaking, Babbel forces you to actually speak. With its speech recognition software, you get real-time feedback on your pronunciation and become familiar with accents.

Babbel lessons also incorporate cultural tidbits that make the course more engaging. For example, you’ll find notes on the country’s traditional foods, customs, etiquette, situations where you might use particular phrases, and more.

To help you form a habit and solidify your memory, Babbel emphasizes spaced repetition techniques, revisiting learned material at strategic intervals. You’re expected to do regular review sessions on top of your daily lessons. While this can feel repetitive, there’s a sense of accomplishment after committing phrases to long-term memory. Some languages also have podcasts that provide more insights into the local culture.

Duolingo’s learning methods and course structure

Duolingo is best known for its quick lessons that take about three to five minutes to finish, making it ideal for busy learners. These short bursts focus on specific skills like vocabulary translation, sentence construction, and listening comprehension.

Duolingo’s magic lies in its gamified approach. Points are awarded for correct answers, streaks are celebrated, and leagues and leaderboards provide a healthy dose of competition.

This gamification keeps users motivated and coming back for more, making language learning feel less like a chore and more like a fun activity. I have to admit, this is the reason why I’ve stuck to the app for years.

Duolingo lessons aren’t the best for learning practical vocabulary. But its more developed courses (Spanish, French, Italian, etc.) include Stories, Radio, and Adventures built into the learning path. There are also Duolingo podcasts that offer more cultural knowledge.

The focus on short lessons and games does come with a trade-off. While there are short grammar guidebooks within units, in-depth grammar explanations are lacking. Apart from the short speaking drills, you won’t find substantial conversational practice. If you’re seeking a more comprehensive understanding of a language’s complexities, you’ll need to supplement your studies with additional resources.

Babbel vs Duolingo: Pricing and free features

Costs can be a huge factor when picking an app. Babbel takes a paid approach with limited free features, while Duolingo offers a completely free option.

Babbel has tiered subscriptions of different lengths (1 month, 3 months, 6 months, 12 months) and prices. Subscriptions start at $13.95 per month but the price decreases the longer you commit (as low as $6.95 per month for a year) and often goes on sale. It also offers lifetime access to all languages.

A Babbel subscription gives you full access to your chosen language, which you can access from your desktop and your mobile device. You get an official Babbel certificate every time you complete a level.

Subscription to the app is available in four tiers too. You can also try Babbel risk-free with its 20-day money-back guarantee. If you’re not quite sold, you can test the first lesson of each course for free.

Duolingo, on the other hand, allows you to access its gamified lessons for free. However, you get limited “hearts” (which limits the number of possible mistakes to five) and no access to the Review section. You’ll also get bombarded with ads from time to time.

To get unlimited hearts and personalized practice sessions, and do away with ads, you can subscribe to Super Duolingo for $12.99/month or $83.99/year ($6.99/month). Super Family, which allows you to share your Super Duolingo subscription with five other users, is available for $9.99/month or $119.99/year. Duolingo Max offers all the benefits of Super Duolingo plus AI-powered features for $29.99/month.

Babbel: Pros and cons

Babbel is one of my favorite language-learning apps for three reasons: lesson quality, speech recognition, and spaced recognition.

Despite being bite-sized and easy to digest, Babbel’s lessons are well-organized, substantial, and practical. The platform focuses on practical conversation skills right from the get-go but you learn phrases holistically through reading, writing (typing), listening, and speaking exercises.

Unlike other apps, Babbel doesn’t shy away from grammar. Grammar tips often show up between exercises, giving more depth to the lessons. I also appreciate that cultural tidbits are woven into the lessons. These don’t just add context but can also be informative and entertaining at times.

My favorite thing about Babbel though is its speech recognition software. It’s one of the most accurate ones out there, requiring you to nail down the pronunciation before letting you move on to the next question. Sure, sometimes I got frustrated about saying the same phrase repeatedly, but this proved useful in developing my speaking skills.

That said, all of these would have been a waste without good memory techniques. Babbel uses spaced recognition to ensure that your learned items stick to your memory. Many apps have some variation of SRS but I found Babbel’s usage effective.

The app features review lessons between regular ones and you also get “Practice” sessions where you’ll need to review a minimum of 10 words daily. It feels satisfying to see a word or phrase get “promoted” to higher levels, indicating that it’s becoming part of your long-term memory.

There are no perfect language learning apps though, and Babbel certainly isn’t.

One limitation is the inconsistency in course content across languages. Some languages, like German, offer advanced lessons, while others, like Russian, only go up to beginner levels. This means you might outgrow Babbel faster depending on the language you’re learning.

Babbel also offers fewer languages compared to Duolingo and other apps. Asian languages are particularly lacking.

Finally, if you’re a fan of gamified courses, you might find Babbel a bit boring. While the lessons can be engaging, they’re not really gamified in the sense that Duolingo is. There are no challenging quests, gems to earn, players to beat, or badges to unlock.

Duolingo: Pros and cons

Let’s start with the obvious: Duolingo is free to use, making it accessible to anyone regardless of budget. Yes, there’s a premium version (which has awesome benefits) but if you’re not too bothered by ads and don’t mind waiting for your “hearts” to be replenished, the free app will suffice.

Another obvious point is that Duolingo is the best at gamifying language learning. It’s what sets it apart. By incorporating points, gems, streaks, and leaderboards into the lessons, Duolingo has kept users engaged and motivated for over a decade now.

Gamification kept the app popular but it also encouraged me to be consistent. Duolingo’s bite-sized lessons take just a few minutes, making it easy to keep the habit of learning. And with the insistent (if not pesky) Duo the Owl and the rest of the gang reminding you to take your lesson, you can’t help but form the habit.

Although not as visible, Duolingo has its iteration of SRS too. You encounter personalized practice sessions throughout the learning path. If you’re using Super Duolingo, there’s a separate review section.

As a Korean learner, I appreciate that Duolingo helps build foundations in non-Latin writing systems. In the Korean course, for instance, the Hangeul characters are included in the earlier units and also available as a separate section.

However, Duolingo focuses heavily on vocabulary and translating between your native and target language. Apart from the few grammar guides, there aren’t in-depth grammar lessons, so you’ll have to learn grammar rules and sentence structure from context.

Additionally, conversation practice is fairly limited. While there are listening and speaking exercises, they’re not within the context of conversations. And more often than not (and this is my biggest complaint), you are learning sentences that aren’t useful in real-life scenarios.

Another drawback is that Duolingo caters more to beginners. The app struggles to challenge advanced learners, and the content can become repetitive.

Finally, the emphasis on gamification can be a double-edged sword. There is an emphasis on maintaining a streak and if you’re not mindful, you can end up prioritizing it over truly understanding the language.

Babbel vs Duolingo: Which is better?

And now, onto the verdict. After pitting Babbel and Duolingo against each other, which one’s the winner?

Besides your target language, you should consider your learning style, goals, and budget when choosing between Babbel and Duolingo.

The truth is, neither Babbel nor Duolingo can get you to fluency. You’ll need more immersive methods such as intensive courses and conversing with locals to achieve this.

But between the two, I’d say Babbel comes closer. It has well-structured lessons focusing on grammar, helping you build strong foundations. It also teaches practical vocabulary. If you crave structure and a deeper understanding of the language, pick Babbel.

Both apps have voice recognition but Babbel’s is more accurate. Duolingo only requires you to articulate over half of the phrase or sentence so you can move on to the next question. Choose Babbel if improving your speaking skills is a priority.

When it comes to gamification and engagement, Duolingo shines. If you prefer a gamified experience and don’t mind focusing on translation rather than in-depth lessons, go for Duolingo.

If you’re a serious learner and willing to pay, Babbel’s comprehensive courses can be a good investment. But Duolingo is a great starting point if you’re new to language learning and prefer to keep things light and fun.

For a more well-rounded learning experience, I recommend combining either of these apps with more resources such as textbooks, online courses on Cudoo, Coursera, and Skillshare, audio-based apps like Pimsleur and Rocket Languages, and language tutors on Preply or italki.

Remember that no single tool can make you fluent. Find the blend of resources and approaches that work for you, keep a realistic routine, enjoy the process, and you’ll get there!

Babbel vs Duolingo: FAQ

Is Babbel better than Duolingo?

There’s no clear winner between Babbel and Duolingo — it depends on your goals. If you’re a beginner seeking a fun and free introduction, Duolingo’s gamification is a good fit. But for serious learners who prioritize grammar, speaking, and a structured path, Babbel’s holistic lessons are better.

Can you try Babbel for free?

Babbel doesn’t offer a completely free version. But it gives you access to the first lesson of each course, so you can see if the format and learning style suit you before committing to a paid subscription.

Can you become fluent on Babbel?

Babbel alone won’t make you fluent in a language. It’s a great tool for building vocabulary and grammar, but fluency requires more. You’ll need real-world practice like conversations, listening to native speakers, and immersing yourself in the language.

Can Duolingo make me fluent?

Fluency on Duolingo alone is unlikely. While it builds vocabulary and introduces a bit of grammar through context, it lacks advanced practice in speaking, listening, and nuanced understanding. Consider Duolingo a springboard to ignite your language journey, but pair it with other methods for fluency.

Can you actually learn a language with Duolingo?

Yes! Duolingo is a great tool to kickstart your language-learning journey. It builds vocabulary and grammar fundamentals through bite-sized exercises. However, it won’t make you fluent. Consider Duolingo a stepping stone and pair it with other resources.

What is the best language-learning app?

There isn’t a single “best” language learning app. But you can consider your goals and learning style to pick the best fit for you. To improve your conversational skills, go for apps like Pimsleur and Glossika. For a strong foundation in grammar, vocabulary, and culture, choose Babbel and Rocket Languages. For gamified exercises, Mondly and uTalk are good choices.
