Duolingo vs Pimsleur: one of them is free

I have not used either app, and everything below comes from what Duolingo and Pimsleur publish themselves. I read every page cited here on 21 September 2026 and I quote it with that date. I also sell a language app, so factor that in. The trade is that you can click each claim and check it, which is more than the pages ranking above me can offer.

All three of them agree on the verdict, by the way: Pimsleur wins on speaking, Duolingo wins on free and on habit. I think that verdict is basically right, so I am not going to pretend otherwise to be interesting. Where they fall down is money, and money is the entire reason you typed this search.

What each one costs, checked today

Start with the awkward part. Pimsleur publishes no price on its own subscriptions page. I fetched it and then opened it in a real browser to be sure, and both times it rendered the plan names, the "7-day Free Trial" button and "51 LANGUAGES -- ADD UP TO 4 USERS" with no dollar figure anywhere.

The one first-party number Pimsleur states lives on its own blog, in a post arguing the subscription is good value: "Both Pimsleur Premium and All Access subscriptions cost around $20 per month." The word "around" is Pimsleur's.

So where do the competing guides get $14.95? I could not find it on anything Pimsleur owns. One page has carried it since September 2024 and has not repriced since.

What I can show you is Apple, which lists in-app purchases by name and price. Here is the Pimsleur listing on 21 September 2026:

Now the caveat that makes this page different from the others. Apple attaches no billing term to any of those. The names carry "Annual" where Pimsleur chose to put it, and the rest are bare. Two separate annual All Access products at $131.99 and $164.99 sit on the same listing, which is a legacy-pricing artifact rather than a menu you choose from.

Duolingo has exactly the same shape, and I wrote it up the same way on Babbel vs Duolingo. Its US App Store listing on the same day showed Super Duolingo at $9.99, $12.99, $83.99, $95.99 and $119.99, with no term attached to any of them, plus "try Super Duolingo for 14 days free". Gem packs sit alongside those at $0.99 to $19.99.

Which means I cannot hand you a clean twelve-month total for either product, and neither can anybody else. A guide that prints "Pimsleur Premium, $14.95/mo" next to "Super Duolingo, $6.99/mo" has manufactured two numbers Apple does not show and the companies do not publish. Open both listings in your own store, where the term is attached and the currency is yours.

One more thing worth knowing before you budget. Duolingo Max, which one guide still presents as a live $30-a-month option, is reportedly no longer offered to new subscribers as Duolingo folds its AI features into Super. Duolingo has not published a page announcing that, so I will not state it flatly, and the Apple listing I read carries no Max product at all. Check the tier list in your own store before you plan around it.

The comparison everyone dodges: $0 against $240

Every guide ranking for this search frames the decision as roughly $13 a month against roughly $20 a month. That framing is wrong at the root, and the error flatters the expensive option.

Duolingo's core course is free. Permanently, ad-supported, and it is the full course rather than a sampler. The gate is Energy, a battery lessons consume and you refill by answering correctly, watching an ad, or spending gems. Super removes the ads and the cap.

So for most people the honest question is whether Pimsleur is worth roughly $240 a year more than a product that costs nothing. Framed that way, you evaluate Pimsleur against free rather than against a $7 difference, and the bar goes up a lot.

I think it clears that bar for a narrow group and misses it for most people, and section four is me trying to say which is which instead of splitting everyone into casual and serious.

The free tier does cost you something real, to be fair to Pimsleur. It costs attention, and it costs control over when your session ends, because the app decides rather than you. Some people find that unbearable and pay to remove it, which is a legitimate reason to buy Super and has nothing to do with Pimsleur.

Where the other guides disagree, and who is right

Three pages, three answers to simple factual questions. Sorting that out is more useful to you than a fourth opinion.

How long is a Pimsleur lesson? The guides say 45 to 60 minutes, roughly 30 minutes, and 10 to 30 minutes. Pimsleur's own homepage says 30 minutes, twice: "Listen & learn in 30 minutes" in its own description of how the product works, then "just 30 minutes a day" in the body copy. The 45-to-60 figure matches nothing Pimsleur publishes. The shorter figures probably come from the Bite-Sized Lessons and practice games Pimsleur sells around the core lesson, which are real products and are not the lesson.

How many languages does Duolingo have? The guides say 35+, 39 and 40+. All three are answering the wrong question, and the right one is on Duolingo's own blog. On 22 April 2026 Duolingo announced that nine courses teach through CEFR B2, and said what the ceiling used to be in its own words: "Previously, most of these learners could only complete content up to A2 (Duolingo Score 59)." The nine are English, Spanish, French, German, Italian, Portuguese, Japanese, Korean and Chinese.

Check your language against those nine first. Whether Duolingo offers 39 courses or 41 matters far less than whether yours stops at A2, which is the level where you can complete a transaction and not hold a conversation.

Do the star ratings mean anything? One guide compiles four sources, which is genuinely the best evidence move on any of these pages, and then quotes Trustpilot scores of 2.5 for Pimsleur and 1.6 for Duolingo as though they sat on the same scale as the app stores. Apple shows Pimsleur at 4.7 from 30K ratings and Duolingo at 4.7 from 5.5M, both read on 21 September 2026. A Trustpilot page for a consumer subscription collects the people who wanted to complain about a charge. Reading 1.6 as a product score, next to 4.7 from five and a half million, treats a self-selected sample as a rating.

Pick by your situation, not by "casual or serious"

That binary is doing all the work on all three pages, and it is a flattering way to sell the pricier option, since nobody types this search hoping to be told they are casual.

You commute and cannot look at a screen. Pimsleur, easily. This is the situation the product was designed around, it runs on CarPlay and Android Auto, and it is the one case where its audio-only design is the feature rather than the limitation.

You are learning a language with a non-Latin script. Duolingo, at least to start. It publishes writing-system tools and says it "has developed a series of tools to help you learn to read in languages that use other writing systems", naming Russian, Greek, Arabic, Hebrew, Hindi and others. An audio-only course leaves you unable to read a sign. This is the sharpest divergence between the two and no guide above me mentions it.

You need to read signage, menus or sit an exam. Duolingo, or a textbook. Pimsleur sells Reading Lessons as a separate activity, and reading is not what the core method is for.

You have quit three apps already because you stopped opening them. Duolingo, free tier, and do not overthink it. Its habit machinery is the best in the category, and the cheapest product is the one you will still be using in March.

You already have a tutor and you keep forgetting what they taught you. Neither of these, and that is the honest answer even though it is bad for my own commercial interests in a different direction. See the next section.

What both of them are bad at

Every comparison of these two treats it as a horse race with a winner. The more useful finding is what happens to you after six months of either one.

Pimsleur gives you speaking practice and a genuine spaced-repetition ancestry. Its method is built on Graduated Interval Recall, which reminds you of new words at growing intervals, and that idea predates every app in this comparison. What it reviews is its own course vocabulary, on its own schedule, and it will not review the phrase you fumbled on the phone yesterday.

Duolingo has the retention mechanics and the reading and writing, and it does have speaking exercises, more than its critics admit: repeating words, translating sentences out loud, spoken dialogues, and a microphone option on many written items. The catch is what sits on the screen while you speak. The target is generally shown or played first, so the hard part, dragging the words out of your own head with nothing to copy, is done for you.

Which leaves the same hole in both. Kang, Gollan and Pashler (2013) tested exactly this with 40 Hebrew nouns: one group heard each word and repeated it, another tried to produce it from memory before hearing it. Two days later the retrieval group was better at comprehending the words, better at producing them, and no worse at pronunciation. The test was picture-naming of single words, so do not stretch it to conversational speech, but the direction is clear enough.

So a learner on either product alone tends to plateau in the same place: understanding a lot, producing much less. We wrote up why that gap opens in input versus cards and what it feels like in the intermediate plateau.

That gap is the thing I built Verbamor for, and here is the honest version of the pitch. It records a real lesson or conversation, pulls out the words and phrases you personally got wrong, and turns those into cards scheduled by FSRS with audio and an image. It teaches you nothing new, it holds what somebody else taught you, and it costs $19.99 a month or $129.99 a year with a 7-day trial on the annual plan. Both are US prices, read off the app's own plan definitions on 21 September 2026; the App Store sets a different number in other countries. There is no free tier, so if the free-versus-paid argument above landed with you, that argument applies to me too. It also only covers Spanish, French, Italian, Portuguese and Russian, and only on iOS.

If you have no tutor and no conversations yet, Pimsleur or Duolingo is a better use of your next $20 than I am. You need material before you need a system for keeping it.
