Is Super Duolingo Worth It? The £120 Green Owl

Is Super Duolingo worth it? The standard answer from review sites is a shrug and a "depends how much you use it". That misses the more interesting question, which is what the money is actually buying. On Duolingo, paying subscribers and free users learn from exactly the same lessons. What changed over the last few years is how unpleasant the free version became, and that is a decision the company made, not an accident.

So this is less a review than a receipt. Here is what language learning apps cost in the UK in 2026, why the free tier got worse on purpose, and what the same money buys if you spend it somewhere else.

What Super Duolingo and Duolingo Max cost in the UK

At the time of writing, Super Duolingo costs about £60 a year in the UK on an annual plan, and Duolingo Max, the tier with AI role-play and "explain my answer" features, costs about £120 a year. Prices move with promotions and app store region, so check the in-app price before you pay.

Babbel sits in a similar range for its standard plans, and periodically pushes a lifetime subscription that is advertised at a couple of hundred pounds and frequently promoted at a discount to its list price. That is a separate trap, and we will come to it.

None of this is ruinous on its own. Sixty quid a year is a takeaway a month. The problem is that most people never ask what is on the other side of the line item. A budget that lists "Duolingo £60" tells you the price, never the value.

How the free tier got worse on purpose

When Duolingo launched its first paid plan in 2017, the pitch was explicit. The subscription removed ads and let you download lessons offline, and the company told TechCrunch that its learning content would always be free. Paying was a convenience, not a key to the good stuff.

The content is still free. The access to it is not. From mid-2025 Duolingo started replacing its old hearts system, which only cost you when you made a mistake, with energy, which drains on every exercise you do. Free users start with 25 energy. Get answers right in a row and some trickles back, but even a perfect learner eventually hits the wall and has to wait, watch an ad or pay. Android Authority's write-up of the change cited a Duolingo community poll in which nearly half of more than 11,000 users actively disliked it.

So a Super Duolingo subscription is mostly a fee to remove friction that the same company put there. You are not paying for better French. You are paying to stop being interrupted while you learn the same French.

And it works, commercially. Duolingo's 2025 annual report shows revenue up 39% to $1.04 billion, subscription revenue up 44% to $873 million, and 12.2 million paid subscribers by the end of the year.

Even Duolingo thinks it overdid it

Here is the twist. On the May 2026 earnings call, chief executive Luis von Ahn told analysts: "We are at the same time undermonetized and overmonetized. It is a weird thing." The friction tactics were pushing some people into paying and pushing others off the app altogether, which is a problem for a business whose growth runs on word of mouth.

So the company is easing off. It has started testing longer free trials, and in the spring it added features such as flashcards and speaking practice to both free and paid tiers. Fair play to them. But notice the order of events: the free tier was squeezed until the squeeze started showing up in user numbers, and only then loosened.

That pattern is worth recognising wherever it turns up. A free product builds a huge audience, the company floats or takes big money, and the free tier is slowly made worse until enough people pay to make it stop. It is the same logic as the subscription trap, just with a cartoon owl on the front.

The AI upsell is the same trick, priced double

Duolingo Max roughly doubles the price of Super for conversational AI: role-play scenarios, a video-call character, and explanations of why your answer was wrong. Those are genuinely useful things for a learner. They are also things a general-purpose chatbot will do on a free plan if you ask it to, say, play a grumpy waiter in Madrid and correct your Spanish afterwards.

You lose the structure and the streak, and the free chatbots have their own usage caps. But be clear about what the £60 premium is for. The AI itself is available elsewhere, so what you are buying is the AI packaged inside the app you already have the habit of opening. That might be worth £60 a year to you. Just make the choice knowingly, rather than because the upgrade screen appeared after your third lesson.

What £360 buys instead

Three years of Duolingo Max is roughly £360. Three years of Super is about £180. Here is the alternative most app users never price up.

Community tutors on marketplaces such as italki commonly charge somewhere around $8 to $15 an hour, so call it £6 to £12. Pair the free version of any app (or free flashcard software such as Anki on desktop and Android) with a tutor, and £360 buys roughly 30 to 40 hours of one-to-one conversation with an actual speaker.

That matters because conversation is precisely what apps are worst at. An app can drill vocabulary forever. It cannot make you stumble through ordering a train ticket while a real person waits, which is the bit that turns knowledge into speaking. If your goal is to talk to people, the tutor hours are the higher-return spend. If your goal is a fun ten minutes on the bus, the free tier is fine and the subscription is a luxury, which is allowed, as long as you call it that. Small comforts hardening into fixed monthly costs is how lifestyle inflation works, one reasonable-looking line at a time.

Independent Duolingo alternatives are taking a different bet

Duolingo's scale is also its constraint. A business valued on daily active users needs you opening the app every day, which is why the streak, the leaderboard and the energy bar all point the same way: back into the app. When a company that size squeezes its free users, raises its tiers and then admits it overdid it, it leaves a gap. Learners who wanted a course rather than an energy bar start shopping around.

That gap is exactly the sort that small independent publishers can fill, and learners are the winners when they do. An independent course does not answer to Wall Street's DAU metric, so it can teach differently and charge less.

Kilo Lingo is one of them. It puts a few ideas at the centre of the course rather than the edges:

• Frequency first. Courses start with the most common words in the language, on the premise that the top 1,000 or so words make up roughly 80% of everyday conversation. You learn "because" and "yesterday" before "elephant".
• Comprehensible input. Every story uses only words you have already met, so you can read it without a dictionary, which is how most people actually absorb a language.
• Grammar drills are built into the course itself, with short example-led guides to the rule and where it trips people up.
• Every lesson, story and grammar topic comes with a printable worksheet, and daily lessons can land straight in your email inbox. Both deliberately get you learning outside the app.

That last point is the money-relevant one. An app that hands you a worksheet and emails you the lesson is choosing not to monetise your attention, which is the opposite of an energy bar that rations it. It is also, give or take the pen, the pocket-notebook method in digital form.

On price, the first two chapters of every course are free and the full course costs $5 a month at the time of writing. That is about $60 a year, under Super Duolingo's £60 at current exchange rates and well under half of Max. As with any subscription, prove the habit on the free chapters before you pay.

The lifetime deal and the gym membership problem

Lifetime language subscriptions look like the sensible, grown-up option. Pay once, never think about it again. For the provider, that is the whole point: the cash arrives upfront, and the cost of serving you falls the moment you stop opening the app.

The honest test is the gym test. If you would not pay a year of gym fees upfront in January on the strength of how motivated you feel in January, do not pay for a lifetime of Babbel on the same feeling. A lifetime deal only beats monthly billing if you are still using it years from now, and the people most tempted by it are usually the ones least sure they will be.

The cheapest structure is the boring one. Start on the free tier. If you hit the wall every day for a month, you have proved the habit is real, and a monthly or annual plan is a reasonable choice. Put it in the diary to review at renewal, or better, get someone else to ask you whether you still use it. An external check beats willpower for subscriptions in exactly the way it does for language practice, and it slots neatly into the spending step of the UK personal finance flowchart.

Frequently Asked Questions

Is Super Duolingo worth it?

It is worth it if you use the app daily and the energy limit or ads genuinely stop you learning. It does not unlock a better course, as free and paid users get the same lessons. If you only do a lesson or two a day, the free tier covers most of what you need.

How much does Duolingo Max cost in the UK?

Duolingo Max costs about £120 a year in the UK at the time of writing, roughly double Super Duolingo at about £60 a year. Prices vary with promotions and app store region, so check the in-app price before subscribing.

Can you learn a language on Duolingo for free?

Yes. Duolingo's core lessons are available on the free tier, with the AI extras reserved for Max. The limits are on how much you can do in one sitting, through the energy system and ads, not on what you can learn.

Is a Babbel lifetime subscription worth it?

Only if you are confident you will still be using it in several years' time. In my view, lifetime deals work commercially for the provider partly because plenty of buyers stop using them long before the maths would favour them. Prove the habit on a free or monthly plan before paying upfront.

What is the cheapest way to learn a language properly?

A free app or free flashcard software for vocabulary, plus regular paid conversation with a tutor. Community tutors on online marketplaces often charge around £6 to £12 an hour, and speaking practice with a real person is the part apps cannot replace.
