Speakly vs Duolingo: which app teaches you to speak?

Two apps, two bets: Speakly drills the 4,000 words you'll use most, Duolingo makes you practise every day. What each one does for your speaking.

Speakly vs Duolingo comes down to one trade: Speakly gets you to useful vocabulary faster, Duolingo keeps you coming back every day in far more languages. If you want to hold a real conversation on a trip or at work, neither app does that alone, so the useful question is which one prepares you better for the person you'll eventually talk to.

Every fact below comes from Speakly's website, the two US App Store listings and Duolingo's Help Center, checked on 27 September 2026.

How are Speakly and Duolingo different?

Speakly and Duolingo teach with different methods. Speakly teaches "the 4,000 most statistically relevant words" of a language, reviewed with spaced repetition, then asks you to use them in simulated everyday situations. Duolingo builds short lessons around themes, with streaks and leagues to keep you practising, across more than 40 languages.

Verdict: Speakly is the more direct vocabulary tool, Duolingo is the easier habit, and only Speakly's optional community puts a human on the other end.

Which app gets you speaking sooner, Speakly or Duolingo?

Speakly gets beginners to usable sentences sooner, because it teaches words in order of frequency, so you learn the ones you'll need before the rare ones. Duolingo spreads the same time across themes, grammar tips and game mechanics, which keeps you motivated but moves your vocabulary more slowly.

What does Speakly do for your speaking?

Speakly's App Store listing describes "Real-Life Situations" (simulated everyday scenarios) and voice-recognition pronunciation with live microphone feedback. The situations are prepared scenes, not open conversations: you answer what the app expects. Speakly also stops being useful once you know its core list, so it suits beginners and lower intermediates.

What does Duolingo do for your speaking?

Duolingo's free lessons include short exercises where you say a sentence out loud. The bigger speaking features sit in Duolingo Max: Roleplay, where you follow a scenario with an app character, and Video Call with Lily. According to Duolingo's Help Center, Video Call works on iOS and Android for Max subscribers learning English, French, Spanish, Italian, German or Portuguese.

Speakly or Duolingo: which is better for Spanish, French or Italian?

For Spanish, French or Italian, both apps are available from English, so the choice depends on your goal. Speakly suits someone with a trip or a move in a few months who needs everyday words fast. Duolingo suits someone who wants a free, low-pressure daily routine and doesn't mind a slower pace.

If Spanish is the target and you work full time, our routine to learn Spanish fast with a job shows where an app fits in a week: on the days without a lesson, for 15 to 20 minutes. The Spanish learning hub gathers our other guides for that language.

Is Speakly or Duolingo worth paying for?

Duolingo is worth paying for only if the ads or the hearts system stop you from practising, since the lessons themselves are free. Speakly is worth one paid month if its trial showed you learning words you can use, because its value is front-loaded: once you know the 4,000 words, the app has less to teach you.

Here is how to decide in a week:

  1. Start Speakly's 7-day trial and note how many of its words you'd say on a normal day.
  2. Use free Duolingo in parallel for the same week.
  3. Keep the one you opened without forcing yourself, and drop the other.
  4. Book one speaking session with a person before paying for anything else.

Can Speakly or Duolingo replace a tutor?

Speakly and Duolingo can't replace a tutor for speaking, because both apps script what you say and neither asks you the unexpected follow-up question a real conversation throws at you. A tutor corrects you mid-sentence and makes you rephrase, and that correction is what builds the reflex to speak.

I'm learning English with a tutor on Preply, and I also practise out loud with ChatGPT's voice mode in the morning while stuck in traffic. My problem at B1 was expressing myself out loud, and I credit my fast progress to speaking for most of each 50-minute lesson with a real person. I cover the cost and the booking in my Preply review, and if you're choosing a tutoring site, the Preply vs italki comparison explains the two billing models.

Skip paid tutoring if you can't give it one slot a week yet: in that case, a free app and a weekly language exchange are the better start. If a trip is coming, our page for people preparing to travel lists the situations worth rehearsing first.

OUR VERDICT
Beginner with a deadline in one of its 10 languages: Speakly, for the vocabulary. Casual learner who wants a free daily habit or a language Speakly doesn't teach: Duolingo. Anyone who needs to speak soon: either app plus one weekly lesson with a person.

Questions people ask about Speakly and Duolingo

Is Speakly better than Duolingo?

Speakly is better for building useful vocabulary quickly, because it teaches words in order of frequency and repeats them before you forget. Duolingo is better for keeping a daily habit and for choice of language: it offers more than 40, against 10 courses from English on Speakly. For speaking with a person, neither replaces a conversation.

Is Speakly free?

No, not in the long run. Speakly offers a 7-day free trial, then paid plans. On the US App Store (checked September 2026), in-app purchases start at $9.99 for one month and go up to $89.99 for lifetime access. Duolingo's core lessons stay free, with ads.

Which languages does Speakly teach?

From English, Speakly's website lists 10 courses: Spanish, French, Italian, German, Brazilian Portuguese, Russian, Swedish, Norwegian, Finnish and Estonian. There is no Japanese, Korean or Chinese, which Duolingo does teach.

Can Duolingo teach you to speak a language?

Duolingo can get you saying simple sentences out loud, and Max subscribers can talk with the AI character Lily in Video Call for English, French, Spanish, Italian, German and Portuguese. It won't give you the pressure of an unscripted conversation with a person who asks follow-up questions.

Should I use Speakly and Duolingo at the same time?

Only if you have the time for both. Two vocabulary apps compete for the same 15 minutes a day. A better pair is one app for vocabulary and one speaking slot a week with a tutor or a language exchange partner.
