Spanish vocabulary app·frequency-first

The Spanish vocabulary app
that actually builds comprehension.

Most Spanish vocabulary apps teach words by theme. You learn "the bear drinks milk" before you can order a coffee. That is not an accident — it is a design flaw.

This app ranks every word by how often it appears in real spoken Spanish. Learn 1,500 words in frequency order and you will understand 80% of everyday Spanish. That is the whole system.

The vocabulary problem

Why most Spanish apps
leave you unable to understand anything.

The top 100 Spanish words account for 50% of all spoken language. The top 1,500 cover 80%. Every Spanish vocabulary app teaches you words — but almost none of them teach you the right words first.

01
Thematic order wastes your time
Duolingo, Babbel, and Rosetta Stone group words by topic: colours, animals, travel. The issue is that "purple" (rare) gets learned before "because" (one of the most common words in Spanish). Theme-first is intuitive. It is also slow.
02
You cannot understand real Spanish yet
After 6 months on Duolingo, most learners can pass their own lessons but cannot follow a real conversation. The gap is vocabulary coverage — specifically, the 200–400 high-frequency words that appear in almost every sentence but that themed apps deprioritise.
03
No one tells you how far you are
Popular apps measure streaks, XP, and lessons completed. None of them tell you what percentage of real Spanish you can actually understand. Progress feels abstract because it is measured in the wrong units.

The difference that matters is not design or gamification — it is whether the app teaches words in the order that builds real comprehension fastest.

How it works

Three things no other
Spanish vocabulary app does.

Frequency-first
Word #1 is more useful than word #2. Always.
Every word is ranked by how often it appears in real spoken and written Spanish — corpus data, not editorial opinion. You learn the words that unlock the most comprehension first. No gaps, no skips, no "I know 500 words but cannot follow a conversation."
Spaced repetition
Built in. Pre-configured. Nothing to set up.
Words are reviewed just before you would forget them — the algorithm spaces each card based on how well you know it. Hard words come back in hours. Solid words come back in days, then weeks. The science of spaced repetition without the manual configuration of Anki.
Comprehension %
Not a streak. An actual number that means something.
After every session you see what percentage of real spoken Spanish you can now understand — based on lexical frequency research. Learn 100 words and you are at around 50%. At 1,500 words you hit 80%. The goal is always visible.
Getting started

How the Spanish vocabulary app works

No setup. No deck building. Open it and start with word #1 — the most common Spanish word.

1
A word appears
A Spanish word is shown. Try to recall its meaning before revealing it. The order is always frequency-ranked — you are always working on the highest-value words.
2
Rate how well you knew it
Easy, hard, or blank? Your rating tells the spaced repetition algorithm when to show this word again. The harder it was, the sooner it returns.
3
New words unlock automatically
As you lock in existing words, new ones are introduced at the right pace. You are never overwhelmed and never bored — the system balances review and new learning for you.
4
Your comprehension % climbs
Every word you master increases the percentage of real Spanish you can understand. The number is calculated from corpus data — it reflects real-world comprehension, not app points.
The research behind it

The 80% comprehension threshold at 1,500 words is based on lexical frequency research — specifically Paul Nation's work on vocabulary coverage in natural language, which shows that the most frequent words in a language carry a disproportionate share of communicative load.

Questions

FAQ

What is the best Spanish vocabulary app?+

The best Spanish vocabulary app is one that teaches words in frequency order — starting with the most commonly used words first. comprendo. pre-ranks 1,500+ words by how often they appear in real spoken Spanish, with spaced repetition built in and a live comprehension percentage so you always know where you stand.

How many Spanish words do I need to learn?+

The top 1,500 most frequent Spanish words give you roughly 80% comprehension of everyday spoken Spanish. The first 100 words alone cover about 50% of all speech. Learning in frequency order means every word you add has a measurable impact on what you can understand.

Is this app better than Duolingo for vocabulary?+

For vocabulary specifically, yes. Duolingo organises words by theme rather than frequency, which means you learn less-common words before mastering the high-frequency ones that appear in almost every sentence. comprendo. teaches words in the order that builds real comprehension fastest. You can read a full comparison in our guide to the best Spanish learning apps.

How is this different from Anki?+

Anki is a powerful general-purpose flashcard tool — but you have to find or build your own Spanish deck, decide what order to learn words, and configure the spaced repetition settings yourself. comprendo. is purpose-built for Spanish vocabulary: the deck is pre-built, words are frequency-ranked, and spaced repetition is pre-configured. You open it and start learning in seconds.

How long does it take to reach 80% Spanish comprehension?+

At 15–30 minutes of daily study with spaced repetition, most learners reach 1,500 words — and 80% comprehension of everyday Spanish — in 6 to 9 months. The exact timeline depends on consistency and prior language learning experience.
