Duolingo does one thing better than anything else on the market: it gets you to start. The interface is good, it is free, and the first week happens by itself. The problem shows up later, when you notice you can recognise hundreds of words and cannot hold two minutes of conversation.
Why that happens
It is not a flaw in the execution, it follows from the format. Multiple-choice exercises train recognition: you are shown a word, you identify it. Conversation demands the reverse — you want to say something and have to produce the word in under a second while building a sentence around it.
These are different skills, and training one does not hand you the other. That is why "I know a lot of words and freeze anyway" is so common among people with long streaks.
Add the energy system, which in practice caps free use at roughly 15 to 20 minutes a day, and you have an app designed for a short daily return. Excellent for building a habit, insufficient for spoken fluency.
The options when conversation is the goal
Exchange with native speakers: HelloTalk, Tandem, Speaky
You are paired with a native speaker of your target language who wants to learn yours. You correct each other.
Works when: you already have enough grounding to form sentences, and you can tolerate writing badly in front of a stranger.
Where it breaks: conversation with a stranger needs a topic, and topics run out. Most pairings die after three exchanges of "where are you from?". Absolute beginners suffer most, because they cannot carry the conversation and the partner drifts away.
Lessons with a teacher: italki, Preply
Works when: you have money and a calendar. Per hour spent it is by far the most efficient method, with nothing close behind.
Where it breaks: cost, and the need to schedule. Practice that requires an appointment is fragile — it is the first thing to go in a busy week.
Talking to an AI: LingChat, Duolingo's own chatbot
Works when: you want to practise with zero embarrassment, at any hour.
Where it breaks: the AI has nothing at stake. It never fails to understand you, never changes the subject because it remembered something, and you have no real reason to reply. Without consequence, the habit does not take.
Talking to people you already talk to: Tokki
This is the lane we are in, so weigh it accordingly. The idea: instead of finding someone new to practise with, the language moves into conversations you already have. You add words to a group's vocabulary and they start replacing themselves inside everyone's messages.
Works when: you have at least one person you message daily, or you are willing to join a public topic group. No schedule and no new topic needed, because the topic already existed.
Where it breaks: if you have nobody to talk to and do not want to join a group of strangers, the model has nothing to offer you. And it is not speaking practice — text does not fix pronunciation or real-time listening.
How to choose
| Your situation | What makes sense |
|---|---|
| Never studied the language | Duolingo, for the first few weeks. It is good at this. |
| Have a base, want to loosen up, have budget | Lessons with a teacher |
| Have a base and want free practice | Exchange apps (HelloTalk, Tandem) |
| Have quit two apps already for lack of time | Something that fits an existing habit |
| Have friends or a partner learning too | Practice inside your own conversation |
The common mistake
Switching apps in the belief that the next one will fix it. Usually the problem was never which app — it was that the method needed a slot in your routine that you did not have. Before installing the next one, answer this: where in my day does this go? With no answer, the new app lasts the same three weeks as the last.
