Airlearn vs Duolingo (2026): Which App Teaches Better?

Pick Airlearn if you want short lessons that explain the rule before they test you, at a lower price. Pick Duolingo if you want the widest choice of languages, a real free plan and a course that goes further.

Airlearn is the new name people keep asking about. It comes from Unacademy, a large Indian education company, and it looks a lot like Duolingo: streaks, XP, weekly leagues and a friendly mascot, a blue cat. Its founder says learners now finish more than 11 million lessons a month, and that revenue grew ten times in a year [8].

So the real question is simple. Is Airlearn a better Duolingo, or just a cheaper copy? We used both apps side by side, on their paid plans, and looked at how lessons teach, how much you speak, and what you pay.

The short answer

How they score

We scored each app out of 10 on the things that matter most once the novelty wears off. Airlearn wins on explanations and value. Duolingo wins on habit, depth and language choice. Speaking is weak in both.

How we tested

We used Airlearn Pro and Duolingo Super on iPhone and Android over several weeks in 2026, and did the same things in both: the first lesson, a week of daily sessions, and the speaking and review features each app offers.

We also read recent App Store and Google Play reviews and checked each app's plans and prices in September 2026 [1][2][3]. Prices change by country, so treat the numbers below as a guide.

What Airlearn is like

Airlearn's idea is "learn first, practise next". Each lesson opens with a few short slides that explain a rule or a group of words, often with a small note about culture. Only then do the quizzes start. Many store reviewers say this is exactly why they switched from Duolingo [1].

It works. On day four of our Spanish course, in a lunch break, a slide explained ser and estar in three lines before the quiz asked us to pick between Soy cansada and Estoy cansada. We got it right because we knew why, not because we guessed. That felt good. It also took less than five minutes, and then the free lessons for the day were nearly gone.

The weak spots are depth and polish. One detailed review found that each lesson teaches only a couple of new words, that the exercises are easy, and that the voice audio is AI-made and sounds robotic, with Chinese tones that are not right [7]. Some reviewers also say speech checking got worse after an update [1]. The free plan stops after about five lessons a day, and Airlearn also has an AI tutor you can call, but reviewers say the calls sit behind a higher paid plan [1].

What Duolingo is like

Duolingo is the app most people start with, and for good reason. Lessons take three to five minutes. You match words, fill gaps and repeat short sentences. Streaks, leagues and a cheeky owl make it easy to come back tomorrow.

The course is also much longer. Duolingo has more than 40 languages, a web version, and units that keep going far past the level where Airlearn's courses start to feel thin. In 2026 it started moving Video Call, where you talk with the character Lily, into the cheaper Super plan, and it stopped selling Max to new subscribers [6].

The honest problem is that Duolingo teaches by guessing. On day twelve of our Spanish streak, on the bus, we built Quiero un café, por favor from tiles without a single mistake. Then a new sentence used quisiera, and there was no note on why. We tapped the tip page later that evening, but it was short. The free plan also has ads and an energy limit that many learners find annoying [3].

Lessons and grammar

This is where Airlearn earns its good ratings. You see the rule, you see an example, then you practise it. If you are the kind of learner who wants to know why a sentence works, Airlearn will feel kinder than Duolingo from day one.

Duolingo gives you more practice for each rule, and more rules overall. Its course is tested on millions of people and builds in small steps. But it leaves most of the explaining to you, and many learners end up looking up grammar on YouTube.

The catch with Airlearn is how much each lesson holds. Clear slides are nice, but if a lesson only adds two words, you need many lessons to get anywhere, and the free plan limits how many you get each day [7].

Speaking and listening

Neither app is a speaking app. Both ask you to repeat short sentences into the microphone, and both check mostly whether they heard the right words, not how you said them.

Our day nine test in Japanese showed the gap well. Sitting at home in the evening, we said Sumimasen, eki wa doko desu ka? to Airlearn twice and it marked us wrong both times, so we switched speaking off and tapped the answer instead. Store reviewers describe the same thing [1]. Duolingo heard the same sentence fine, but also let a clearly wrong vowel pass.

For real conversation, Duolingo's Video Call is the better first step today, since it is moving into Super [6]. Airlearn's AI calls exist, but you pay more for them [1]. Listening is also better on Duolingo, because Airlearn's AI voices do not sound natural yet [7].

Feature by feature

✓Yes◐Partly✕No

Duolingo is the wider app, with more languages, a free tier worth using and a web version. Airlearn does less, but explains more, and costs much less.

Price and plans

Prices are US App Store prices checked in September 2026 [1][3]. They vary by country and by offer, so check the price in your own store before you pay. Airlearn's AI calls need a higher plan than the basic Pro price shown here.

Who should pick which

Pick Airlearn if you are a beginner who wants to understand the rule before you practise it, you learn one of its main languages, and you want to pay as little as possible. It is also one of the few apps with Hindi and other Indian languages.

Pick Duolingo if you want a free plan you can really use, your language is not on Airlearn's list, or you plan to keep going past the beginner stage. It is still the best habit builder there is.

Conclusion

Airlearn is not just a cheap copy. It fixes Duolingo's biggest problem, the lack of explanations, and it costs about half as much. But it is young, its lessons are thin, and its AI audio still sounds like AI. Duolingo is bigger, deeper and better at keeping you coming back. If you are starting from zero and want to know why, try Airlearn. If you want a long course in almost any language, stay with Duolingo. Either way, add real speaking practice somewhere else.
