Spanish vocabulary is the single biggest barrier between a beginner and actual fluency. Grammar rules are learnable in a few months.
But the vocabulary gap (the 5,000 to 10,000 words you need to read, speak, and understand comfortably) takes sustained effort. Spaced repetition is the most efficient way to close it.
Free to start. No credit card required.
Building Spanish vocabulary with spaced repetition means every word you learn gets reinforced at increasing intervals: the day after you learn it, then three days later, then a week, then two weeks. Each retrieval strengthens the memory. After a few cycles, the word stops needing review and becomes automatic.
The algorithm tracks every card and shows it again right before you would forget it. No manual planning required.
Every review session is a test, not a reading. Pulling information from memory is what builds lasting retention.
Space Repeat is completely free. No paid tier, no feature walls, no subscription required to access spaced repetition.
Yes, completely free. Build Spanish vocabulary decks by topic or frequency level and review with full spaced repetition at no cost.
Start with a high-frequency vocabulary deck (top 500 or 1,000 words), then build topic-specific decks: food, travel, work, or any area relevant to your goals. Keep verb conjugations in a separate deck so you can drill them without mixing them into your vocabulary review.
With 1,000 high-frequency words and basic grammar, most learners can hold simple conversations. At 20 minutes of daily review plus active practice (listening, speaking), reaching this level takes three to six months for most English speakers. Spaced repetition makes sure the words you learn in month one are still accessible in month four.
The Best Flashcard App for Language Learning
Learning a language is a vocabulary problem. Flashcards fix this faster than almost any other method. Here are the best flashcard apps for language learning.
Active Recall: The Most Effective Study Technique (Backed by Science)
Most students study by re-reading their notes. Research consistently shows this is one of the least effective methods available. Active recall works differently, and the results are dramatically better.
Space Repeat vs Duolingo
Duolingo and Space Repeat are solving different problems. Duolingo is a gamified language-learning app designed to build a daily study habit through streaks, points, and short lesson modules. Space Repeat is a spaced repetition flashcard app designed to maximise long-term vocabulary retention. Most serious language learners end up using both. Here's why, and how to decide what you need.
