Mondly vs Duolingo, and the European Portuguese course neither delivers
Mondly vs Duolingo splits cleanly by method: Mondly drills practical phrases with speech recognition across a wide spread of languages, while Duolingo is the free, gamified daily-habit app almost everyone starts with. Duolingo wins on price and on keeping you coming back; Mondly wins on travel-ready phrases and is often sold cheap or as one-time lifetime access. For a life in Portugal, though, the honest verdict is that neither delivers a European Portuguese course built for the country. Duolingo has none at all, Mondly's Portugal option is a thin phrasebook, and that gap is what TangoLango fills.

The short answer
Duolingo is the better free habit, Mondly is the better phrasebook, and neither is built for European Portuguese. Duolingo keeps you tapping ten minutes a day with a streak that genuinely works, and it costs nothing unless you pay around $7 a month for Super. Mondly focuses on short, practical dialogues with speech recognition and sells a lower subscription that is regularly discounted, sometimes as a lifetime deal. Both are fine at what they do. The catch for anyone moving to Portugal is the dialect: Duolingo's only Portuguese is Brazilian, and Mondly, while it does surface a Portugal setting, keeps it shallow.

Where Mondly is the stronger of the two
Mondly is the better tool if you want to walk into a country able to say useful things fast. Its lessons are built around short, practical dialogues, the speech recognition gives you something to speak against, and the daily lesson plus weekly and monthly challenges keep a light structure. It also spreads across a lot of languages and throws in a chatbot and augmented-reality features that Duolingo does not. What it does not do is teach much grammar or adapt to you. The content is fixed and general, so it prepares you for a phrasebook conversation. The exact message your landlord just sent is outside its script. Its European Portuguese support, in particular, is thin enough that Portugal-based learners routinely bounce off it.
Where Duolingo comes out ahead
Duolingo wins on habit, price and reach. It is free, the streak is the best motivator in the category, and it covers far more languages than most rivals. The trade-offs are real and worth saying: the gamification can tip into busywork where you tap tiles more than you produce sentences, and the 2025 push toward AI-generated content and staff cuts cost it a lot of goodwill. For Portuguese there is no way around the dialect. Duolingo's only Portuguese course is Brazilian, per its own course list (checked July 2026), so a learner in Lisbon or Porto trains the wrong accent and the wrong everyday words, with no toggle to fix it.
The Portugal problem both of them share
Brazilian and European Portuguese read alike on the page and pull apart the second someone speaks, which is exactly where daily life happens. European Portuguese swallows unstressed vowels, keeps the tu forms Brazil often drops, and swaps everyday words: a bus is an autocarro not an ônibus, a phone is a telemóvel not a celular, breakfast is pequeno-almoço not café da manhã. Duolingo skips the Portugal dialect entirely and Mondly treats it as a light setting, so both leave you understanding a Brazilian speaker better than your own neighbour. The European Portuguese overview documents the split, and it is the whole reason a dedicated tool exists.
Choose Mondly, Duolingo, or the Portugal-built option
Choose Duolingo if you want a free daily habit and are not learning specifically for Portugal. Choose Mondly if you want quick, practical travel phrases with speech practice and like its lifetime pricing. Choose TangoLango if you live in or are moving to Portugal and need the language of your week rather than a fixed deck. It teaches European Portuguese only, checks every sentence for the dialect, speaks it in native Portugal voices, and turns the situations you actually hit into flashcards through a tutor you chat with in the app. Many people start on Duolingo or Mondly and switch once the generic content runs out of road. For the wider field, here are the Duolingo alternatives worth switching to and the Pimsleur and Duolingo matchup.
"Mondly got me some phrases and Duolingo kept me tapping, but the day I actually needed to answer my landlord in Portugal, neither had taught me a word of it. One teaches Brazilian, the other barely does Portugal. That is the exact hole TangoLango was built to fill."
Frequently asked questions
Is Mondly or Duolingo better?
Neither wins outright. Duolingo is better for a free daily habit and covers more languages; Mondly is better for practical travel phrases with speech recognition and often sells cheaper. For learning Portuguese in Portugal, both fall short: Duolingo teaches Brazilian only, and Mondly's European Portuguese support is thin. A dedicated European Portuguese tool serves that goal better than either.
Can you become fluent with Mondly?
Not on its own. Mondly builds a useful base of practical phrases and some listening, but fixed phrasebook content and light grammar will not carry you to fluency, and it does not practise you on your own real situations. Most people who get fluent pair a phrase app with real conversation, native audio, and material drawn from their actual life.
Why are people ditching Duolingo?
A mix of reasons: the gamification can feel like busywork, the 2025 shift toward AI-generated lessons and staff cuts drew a backlash, and for specific goals like European Portuguese it simply does not teach the dialect. See more on why people are leaving Duolingo and what they move to.
Who is Duolingo's biggest competitor?
It depends on the job. Babbel and Mondly are the closest broad rivals, Pimsleur owns audio, and Memrise competes on native-speaker clips. For European Portuguese specifically, none of the big apps is built for the Portugal dialect, which is where a focused tool like TangoLango comes in rather than a general Duolingo rival.
