Duolingo vs Better Español: An Honest Comparison

What Duolingo is genuinely excellent at

Duolingo solved the hardest problem in language learning, which is getting people to come back tomorrow. The streak, the leagues, the animations — it is easy to be sniffy about all of it, and it works. Millions of people have practised a language for a hundred consecutive days because of a cartoon owl, and no amount of methodological purity beats that.

The course itself is well built for the first few hundred hours. Grammar is introduced implicitly through examples rather than tables. Sentences are drilled in both directions. There is audio throughout, and the recent conversation features are a real improvement. If you are starting from zero, it is still one of the best first steps available.

Where it leaves you short

The complaint that shows up in every long-term Duolingo discussion is the same: people finish large parts of the tree and still cannot follow a conversation. There are two structural reasons.

• The vocabulary ceiling is low. Duolingo's Spanish course teaches on the order of two to three thousand words across its entire length, and much of it is course-specific rather than frequency-ordered — you will meet the word for owl well before some far more common verbs.
• Review scheduling is comparatively blunt. Words come back when the course structure brings them back, not when your memory of that particular word is about to fail. Practice sessions are also weighted toward what keeps you engaged, which is not always what you are closest to forgetting.

There is a subtler issue too. Because the exercises are heavily multiple-choice and word-bank based, a great deal of what you practise is recognition rather than recall. You can pass a lesson by identifying the right answer among four, which is a much easier task than producing the word unprompted — and it is production that a conversation demands.

What Better Español does instead

Better Español is not a course, and it does not try to teach you grammar. It does one thing: it puts Spanish vocabulary into your long-term memory and keeps it there.

• Words arrive passively through lock screen and home screen widgets, so exposure costs no scheduled time at all.
• Reviews are scheduled by FSRS, which models how fast each individual word decays for you and shows it at the point recall is about to fail.
• Every word comes with pronunciation and a natural example sentence, so you learn usage rather than a translation pair.
• The built-in dictionary lets you save any word you meet elsewhere — including in Duolingo — straight into your own review queue.
• Decks are organised by CEFR level, so the order is roughly frequency order rather than course order.

The honest recommendation

Use both. They are not competing for the same job.

If you are at zero, start with Duolingo. Grammar you absorb from examples is worth more than grammar you are taught, and nothing else makes the first month as painless. Add Better Español once you have a rough sense of how Spanish sentences are shaped — usually a few weeks in — and let it carry the vocabulary load that the course is not built to carry.

If you have already done a long Duolingo streak and feel stuck, the diagnosis is almost always vocabulary. You know how Spanish works and you do not know enough words to use it. That is a solvable problem, and it is precisely the one spaced repetition was built for.

One thing Duolingo does that we do not

Duolingo will get you to speak, badly and early, and that is genuinely valuable. Its exercises force production and its speaking features force pronunciation, awkward as both are.

Better Español has no speaking component and no grammar instruction. If you use it alone you will build a large passive vocabulary and no ability to deploy it. Pair it with something that makes you produce language — a course, a tutor, a very patient friend — and the combination is far stronger than either half.
