Fluentra vs Duolingo for Learning English: An Honest Comparison
Duolingo is the better habit-builder and it's free. Fluentra is a longer, structured course with a level test and an A1 to C1 path. Here's how to tell which one you need.
On this page
Choose Duolingo if you want a free, game-like daily habit, your whole course in your own language, and you're happy to reach around B2. Choose Fluentra if you want a structured course with planned grammar and longer lessons, a level test before you start, and a path that continues to C1. Many people use Duolingo for a daily habit and a course for depth; you don't have to pick only one.
A note on fairness: we make Fluentra, so we aren't neutral, and Duolingo does several things better than we do. What we say about Duolingo comes from its own help centre, blog and App Store listing, checked on 13 November 2026, and the sources are listed at the end. Duolingo tests features and prices, so what you see may differ.

Where Duolingo is stronger
- It's free. Duolingo says every course is free. You'll see ads, and Super removes them, but you can learn a lot without paying anything.
- Habit. Short lessons, streaks and a clear next step make it easy to practise every day. That consistency is worth a lot.
- Your language, all the way through. Duolingo's catalogue lists English courses for speakers of 31 languages, from Spanish and Chinese to Tamil and Marathi, and the course is taught through that language. Fluentra only does this in A1.
- Phone app and AI conversation. Duolingo Max adds Video Call with its character Lily and Roleplay. Duolingo lists Roleplay for English learners who speak Spanish, Portuguese, Japanese, German or French. Fluentra has no AI conversation partner and runs in the browser rather than as a store app.
- An official test from the same company. If you need a score for a university application, the Duolingo English Test is a separate exam taken online. Its official blog lists it at US$70, in about an hour.
Where Fluentra is stronger
- A planned path to C1. Duolingo's own blog says its most advanced courses teach up to a Duolingo Score of 129, which it puts at the end of B2. Fluentra has five courses from A1 to C1, so B1 and B2 learners have somewhere to go next.
- Grammar explained in order. Each Fluentra lesson moves through new words and grammar, reading or listening, practice, speaking and a real-life task, and practice answers come with the reason they're right or wrong. You can see every lesson of a course on its course page before you begin.
- Longer lessons. Fluentra lessons average about 35 to 55 minutes, depending on the course, and you can stop and resume. That's a cost if you have five minutes, and a benefit if you want depth.
- A level test before you sign up. Fluentra's level test takes about 12 to 15 minutes with no account and gives an estimated CEFR level and a starting course.
- A known price. Fluentra shows its price before you pay; Duolingo's depends on your platform and country and is shown in the app.
Levels and the learning path
Duolingo puts each course on a single path of sections and units. When you add a course you can take a placement to start further along, and you can jump to a later unit by passing a test. In October 2026 its blog described its most popular courses as teaching up to the end of B2, and its help centre says updated courses, including English for Spanish and Portuguese speakers, have added higher sections. We couldn't find an official top level for each English course, so check the course you'd take.
Fluentra is five separate courses, Beginner (A1) to Advanced (C1), each with 24 lessons in six modules. There's no C2 course. If you're between levels, take the level test first, then start at the course it suggests. Our guide to CEFR levels explains what each level means.
Speaking practice
Both include speaking, in different ways. Duolingo has speaking exercises in its lessons, and with Max you can have a video call with Lily or role-play a scenario; Duolingo lists Video Call for English learners on iOS and Android. In Fluentra, every lesson asks you to record your answer, play it back and compare it with an example. Tap Check my answer and your recording is sent for transcription, so you can see what was understood; we don't keep the audio. Neither replaces a real conversation partner. Our guide to practising speaking on your own helps whichever you use.
Remembering words
Duolingo's Practice tab includes a Words set, which its help centre says is free on iOS and Android, and Super adds Personalized Practice built from your mistakes. In Fluentra you tap a word in a lesson to see its translation and hear it, save it to My Words, and saved words come back in a short daily practice. Both work if you use them; see how to remember English vocabulary for a method that works with any app.
What it costs
Duolingo's courses are free. Super removes ads and adds features such as unlimited hearts or energy (its own pages mention both), and Max adds the AI speaking features. Duolingo doesn't publish a web price: the price is shown in the app, the US App Store lists several Super options, and the free trial was 14 days on the US App Store and one week on the website when we checked. Duolingo says it tests subscription options.
Fluentra's Lessons 1 and 2 of every course are free once you sign in, and the level test is free with no account.
Full Access is $12 a month or $89 a year in the US, Canada and most of Europe. Prices are set by country, and you see yours before you pay.
Certificates
When you finish every lesson of a Fluentra course, you get a certificate of completion for that course. It shows what you completed, not an exam result. Duolingo's official exam is the Duolingo English Test, a separate paid product that many universities accept; we couldn't find an official statement about completion certificates for Duolingo's courses. For a free certificate you can put on a CV, the EF SET is an option: see free English level tests compared.
Who should choose which
| Choose Duolingo if… | Choose Fluentra if… |
|---|---|
| You want to learn for free | You're willing to pay for a full course after two free lessons |
| You want five minutes a day and a streak | You have time for longer lessons, about 35 to 55 minutes on average, and want depth |
| You want the whole course in your own language | You're happy with English instructions after A1 |
| You want an AI conversation partner or a phone app | You want grammar explained in a planned order |
| B2 is enough for your goals | You want a clear path to C1 |

Questions people ask
Is Fluentra better than Duolingo?
Not in general. Duolingo is free, very good for building a daily habit and teaches English through 31 languages. Fluentra is a paid, structured course with a level test and a path from A1 to C1. Which is better depends on what you need.
Can Duolingo get you to an advanced level of English?
Duolingo says its most advanced courses teach up to the end of B2 on its own scale. For C1, you'll need more: a course that goes further, plenty of real reading and listening, and speaking practice with people.
Can I use Duolingo and Fluentra together?
Yes. Some learners keep a short Duolingo streak for daily contact with English and use a structured course for grammar, longer lessons and speaking. Just make sure the course gets most of your study time.
Does Fluentra have a free version like Duolingo?
Not a free plan for the whole course. Lessons 1 and 2 of every Fluentra course are free once you sign in, and the level test is free with no account. Full access is paid.
Does Duolingo give you a certificate?
Duolingo's official exam is the Duolingo English Test, a separate paid test. We couldn't find an official statement about completion certificates for its courses. Fluentra gives a certificate of completion when you finish every lesson of a course; it isn't an exam result.
