The Best Free Language Learning Apps, and the Honest Point Where Free Stops
Free gets you a long way. For a genuinely free full course, Duolingo is the one to beat: it states every course is free to use with ads. For free speaking practice, exchange apps like Tandem and HelloTalk let you talk with native speakers at no cost. And Mondly has a real free tier of daily lessons and vocabulary review, separate from its paid Premium.
Here is the honest part that free-app roundups skip: free is excellent for vocabulary, habit and casual practice, but it cannot buy a trained teacher who corrects you and pushes you past a plateau. That is not a reason to pay early. It is a reason to use free tools for as long as they are working, then spend a little only when you want correction. When that day comes, the cheapest paid step is a community tutor on italki from about 5 dollars a lesson, not free, but close. Verified July 23, 2026.
What "free" actually gets you
Every free tool on this page is good at the same first job: building vocabulary and the daily habit of showing up. A few hundred words and a routine is exactly what the beginning needs, and paying for that stage is optional. Free exchange apps add something the self-study apps cannot, real conversation, but with other learners rather than teachers. What no free option provides is a qualified person who hears your mistakes, corrects them and explains why. Keep that map in mind and the list below sorts itself.
Duolingo, the best genuinely free full course
Duolingo is the benchmark for free because the whole course is free. It states that everyone can access its courses without spending anything, whether you enrol in one course or forty, with advertising shown to free users. Its paid tiers, Super and Max, remove ads and add features, including AI conversation practice on Max, but you are never forced into them to keep learning.
Use it for: the vocabulary-and-habit stage, in more than forty languages, at no cost. Know its limit: it cannot hear you speak and correct you, and it will not hold an unscripted conversation unless you pay for Max. It is the free layer, not the finish line. We name Duolingo only as a benchmark and do not link to it.
Mondly, a real free tier with a paid path
Mondly runs a genuine free tier, not just a trial: it includes daily lessons, weekly and monthly challenges and vocabulary review, in more than forty languages taught from your own native language. That last part is its edge, because learning from your first language instead of through English removes a translation step, which matters most for a household where English is not the first language.
Be clear about the split, because it is where the money is. Conversation practice, pronunciation lessons, grammar guides and conjugation tables sit behind Premium, so the free tier is a vocabulary tool rather than a complete course. If the native-language angle fits you and you want those extras, Premium is the upgrade. Our Mondly review covers the free-versus-Premium split, the store prices and the refund terms, including that the 14-day cooling-off applies only to UK and EU subscribers.

Tandem and HelloTalk, free speaking with native speakers
If what you want from free is to actually talk, language-exchange apps are the answer the self-study apps cannot give. Tandem is free to make an account, browse profiles and start conversations by text, voice note or call, with native speakers of more than 160 languages. HelloTalk connects you with native speakers across 260-plus languages and tens of millions of learners, also free to use, with a more social, post-and-comment feel. You help someone learn your language while they help you learn theirs.
The honest limit: your partners are fellow learners and native speakers being friendly, not trained teachers. They will chat with you and correct the obvious, but they will not run a structured lesson or reliably explain grammar. For casual speaking reps at no cost, they are excellent. For correction that moves you forward, that is the paid step below. We name both only as benchmarks and link to neither.
Where free stops, and the cheapest way past it
The wall every free learner eventually hits is the same: you can practise endlessly, but nobody qualified is telling you what you are getting wrong. Crossing it is not free, but it is cheaper than people expect. On italki, community tutors set their own prices from about 5 dollars a lesson, and many teachers offer a trial lesson at a reduced price, so you can test a real teacher for the price of a coffee. A single weekly lesson alongside your free app is the combination that actually moves most learners.
That is a genuinely different thing from a free app, because a person hears you speak and corrects you. Our guide to how much italki costs turns the ranges into monthly budgets, and it stays honest about the credit rules, that credits are non-refundable and expire after twelve months of inactivity.

One warning: a free trial is not a free app
Watch the wording when you shop, because "free trial" and "free tier" are not the same thing. A free tier, like Duolingo's courses or Mondly's daily lessons, you can use indefinitely without paying. A free trial, like the seven-day trial some subscription schools run, converts to a paid subscription automatically when it ends unless you cancel first. Lingoda's live classes, for example, start with a seven-day trial that then charges you, so it is a paid product you are sampling, not a free option. There is nothing wrong with trying a paid service, but diary the cancellation date and do not mistake it for free.

If the learner is a child
Free apps suit children well for the vocabulary stage, and a free course keeps the cost at zero while you find out whether the interest lasts. Keep exchange apps for adults and supervised teens, though, because they connect strangers. If you move to paid lessons later, italki states that most of its users are adults, asks parents to create and manage the account and to communicate with teachers, points to its Kids category filter, and tells parents to supervise lessons.
What we would do
Start entirely free. Build vocabulary and a habit on a free course, and if your first language is not English, try Mondly's free tier for its native-language teaching. Add free speaking through Tandem or HelloTalk once you can string sentences together. Then, and only when free stops moving you, add one cheap weekly lesson with a real teacher for correction. That sequence costs nothing for months and only a little after that, and it beats paying for a subscription you will not finish. The three shapes of paid learning, when you get there, are on our language learning hub.
Frequently asked questions
What is the best free language learning app?
For a genuinely free full course, Duolingo, because it states every one of its courses is free to use with ads, so you can reach a real beginner level without paying. For free speaking practice, a language-exchange app such as Tandem or HelloTalk lets you talk with native speakers at no cost, though they are other learners rather than teachers. Mondly also has a real free tier of daily lessons and vocabulary review. The catch that applies to all of them is that free covers vocabulary, habit and casual practice, not a qualified teacher correcting you.
Can you actually learn a language for free?
You can get a long way, but not all the way. Free apps are genuinely good at the first job, which is building vocabulary and a daily habit, and free exchange apps let you practise speaking with native speakers. What free cannot buy is a trained teacher who corrects your mistakes, explains why something is wrong and pushes you past a plateau. Most people learn cheaply for months on free tools, then pay only when they want that correction, which is a sensible order rather than a failure of the free apps.
Is Duolingo completely free?
The courses are. Duolingo states that everyone can access its courses without spending anything, whether you take one course or forty, with advertising shown to free users. Its paid tiers, Super and Max, remove ads and add features such as unlimited energy and, on Max, AI conversation practice, but you never have to buy them to keep learning the language. That makes it the strongest genuinely free option for structured self-study.
Are free trials the same as free apps?
No, and this is where money quietly gets spent. A free tier, like Duolingo's courses or Mondly's daily lessons, stays free. A free trial, like the seven-day trials some subscription services run, converts to a paid subscription automatically when it ends unless you cancel first. If you are shopping for free, look for a free tier you can use indefinitely, and treat any "free trial" as a paid product you are testing, with a cancellation date to diary.
What is the cheapest way to actually speak with a teacher?
Not free, but close to it: on italki, community tutors set their own prices from about 5 dollars a lesson, and many teachers offer a trial lesson at a reduced price so you can test them cheaply. That is the point where paying a little buys something free tools cannot, a person who hears you speak and corrects you. Free exchange apps like Tandem give you conversation partners for nothing, but they are fellow learners, not teachers, so the feedback is not the same.
How we reach these verdicts, and the sources behind them, is on our methodology page. Duolingo's free access and paid tiers come from Duolingo's own statements; Mondly's free-tier and Premium contents from Mondly's own pages; Tandem's and HelloTalk's free language-exchange features and language counts from those apps' own sites; and italki's price bands and trial and credit rules from italki's own pages, all verified July 23, 2026. We do not call any trial or paywalled feature free, and we name Duolingo, Tandem and HelloTalk only as benchmarks with no link. The italki community tutor figure is the lowest rate we saw rather than a fixed rate, because tutors set their own prices; prices verified July 23, 2026. We earn a commission if you subscribe to Mondly or sign up to italki through our links; the free options are included because a page about free apps that hid them would not be honest.
