Why people leave Duolingo
Duolingo is the best free language app in the world, and that is not a backhanded compliment. It is genuinely brilliant at one thing: getting you to show up every single day. The streak, the leagues, the little chime - all of it is engineered to build a habit, and a daily habit is the foundation everything else sits on. If you are still using Duolingo and enjoying it, you do not need this page.
But three kinds of people end up looking for the exit, and it is worth being precise about which one you are, because the right alternative is different for each.
The first group has hit the speaking wall. You can tap the right tiles, you recognise vocabulary, your streak is in the hundreds - and then a real person speaks to you and nothing comes out. This is the most common complaint, and it is baked into the format. Duolingo drills recognition far more than production, and it cannot give you the one thing that builds speaking: a human who responds and corrects you.
The second group is frustrated by the grammar gap. Duolingo teaches by pattern-matching. You absorb structures without ever being told the rule, which works for some and infuriates others. If you are the kind of adult who wants to know why the article changed or why the verb moved, Duolingo's refusal to just explain it becomes maddening.
The third group has simply finished. You have completed the tree, or close to it, and realised it has delivered you to a confident beginner and stopped. The owl has nothing more to teach you, and you want to know what comes next.
Each of those is a different problem, so this page is organised around the diagnosis rather than a generic leaderboard. Work out which of the three you are, and the switch picks itself. If you want a broader app comparison that is not framed around quitting Duolingo, the best language learning apps roundup is the place; this page is specifically about what to do next once Duolingo has let you down.
Match the switch to your reason for leaving
Babbel is the best paid alternative, and the obvious move if grammar is your gripe. Where Duolingo makes you guess, Babbel stops and explains the rule before drilling it - the single biggest upgrade for a literate adult. The lessons are short, dialogue-led and built around things you would actually say, and on the annual plan it works out cheap, around £5-6 a month. The honest caveats: there is no real free tier, it runs thin for Mandarin, and like every app its content thins out past upper-beginner. For Spanish, French, German or Italian, though, it is the app I put in front of friends first. Read the full Babbel review for the detail.
Pimsleur is the best alternative if you cannot speak. It is an audio-first course - thirty-minute lessons you listen to and respond out loud - and it drills speaking and listening harder than any screen app, Duolingo included. There is no tapping, no tiles, no game. It is older, drier and more expensive, around £15 a month, and it builds vocabulary slowly. But if your specific problem is that words will not come out of your mouth, Pimsleur fixes the exact thing Duolingo cannot. It is made for commutes, dog walks and the gym. The Pimsleur review covers who it suits.
italki is what you graduate to, and the best answer to "I finished, now what?". It is not an app in the usual sense - it is a marketplace of real tutors, and once you have the basics, an hour a week here beats any amount of tapping. This is the only "alternative" on the list that solves the speaking wall properly, because it is the only one with a human on the other end. It costs around £8 a lesson for community tutors, less than a streak-freeze habit you will not miss. If you take one thing from this page, take this: the people who get fluent are the ones who make this jump. The italki review explains how to pick a tutor.
Lingoda is the pick if you miss structure. Some people leave Duolingo not because it is too easy but because it is too loose - they want a syllabus, a timetable and a teacher who notices when they skip. Lingoda runs small-group classes online with real teachers, on a real schedule, with certificates at the end. It is the closest thing to a proper language school on this list, and a long way past anything Duolingo offers a learner who wants to be held accountable.
The best free alternative (and the honest bit)
If your requirement is free, you deserve a straight answer, even though it costs us money to give it.
For most people, the best free option is still Duolingo itself - which is awkward advice on a page about leaving it, but true if all you want is a daily habit at zero cost. Nothing beats it for showing up.
But "free and better" is a real search, and there are two genuine answers. Language Transfer is a completely free audio course - no ads, no premium tier, just a generous project - that teaches by reasoning out the grammar with you rather than drilling it. For Spanish in particular it is extraordinary, and for several languages it is simply better than Duolingo at making structure stick. Anki is a free, open-source flashcard app built on spaced repetition; used properly, it beats Duolingo for vocabulary retention by a distance. Neither is polished, neither is gamified, and neither earns us a penny - we are recommending them because they are the right answer.
A word on the other names you will see. Busuu has a useful free tier and a community-feedback feature, though its best parts are paywalled. Memrise leans on video clips of native speakers, which is genuinely good for listening, with a thinner free tier than it once had. LingoDeer was built for Asian languages and is the better starting point than Duolingo if you are learning Japanese, Korean or Mandarin, though it is paid past the early lessons. These are all real, decent tools. None of them changes the underlying truth on this page, so I am mentioning them honestly rather than dressing them up as picks we have tested to the same depth.
What to use after Duolingo
If you have finished the tree, here is the uncomfortable, money-saving truth: stop reaching for another app. Finishing Duolingo puts most people around A2 - a confident beginner who can read and recognise but not yet hold their own in a conversation. Another app will mostly re-teach you what you already half-know, with the same recognition-over-production bias that left you here.
What actually moves you from A2 towards real, usable fluency is producing the language with a person who corrects you. That means a tutor on italki or Preply, an hour or two a week, talking badly until you talk less badly. It is cheaper than people expect, around £8-12 a lesson, and it does in a month what another year of tapping will not.
If you want a bridge before you book a human - to tidy up grammar or get your ear in - Babbel or Pimsleur for a few months is a sensible interim step. But treat it as a bridge, not a destination. The destination is a conversation.
The bottom line
There is no single best Duolingo alternative, because there is no single reason people leave. If grammar is the gap, go to Babbel. If you cannot speak, go to Pimsleur. If you want structure and a timetable, Lingoda. If your requirement is truly free, Language Transfer and Anki are the honest answers, and we earn nothing for saying so. And if you have finished Duolingo and genuinely want to progress, the alternative is not an app at all - it is a real tutor on italki.
Whichever reason sent you looking for the exit, the cure ends in the same place: a person. Every app here, Duolingo included, is a way to buy a cheap head start on your own schedule, and not one of them can replace the messy business of talking to someone who corrects you. Duolingo got you started, which is no small thing. The reason you are leaving is just the signpost pointing at the next step - and the next step is to stop tapping and start talking.
