What is Spaced Repetition?
Spaced repetition is a powerful learning method that strategically schedules review sessions at increasing intervals to maximize long-term memory retention. It's become one of the most popular features in modern language learning apps, transforming how we approach vocabulary practice and memorization. Instead of reviewing everything daily, the system tracks which words you know well and which ones need more practice, then adjusts your review schedule accordingly.
How Does Spaced Repetition Work?
Let's say you're learning the Spanish word "ventana" (window). The first time you see it, you might review it again in 24 hours. If you remember it correctly, the app might wait three days before showing it again. Get it right again? Now you might not see it for a week. But if you struggle with it, the app brings it back sooner – maybe the very next day.
In short, spaced repetition ensures that you're not wasting time reviewing words you already know well. Instead, it makes sure that you're getting extra practice with the ones you find challenging – exactly when your brain needs it.
Best Spaced Repetition Apps For Language Learning
Spaced repetition's effectiveness isn't just theory – it's proven by research. In fact, a 2015 study found that students who waited eight days between learning and review outperformed those who reviewed after just one day. Testing their knowledge five weeks later showed definitively that spacing out review sessions leads to better long-term retention.
Ready to put this science to work in your language learning? We've selected 8 top spaced repetition apps that will help you master vocabulary faster and remember it longer. These apps combine proven memory science with practical features designed specifically for language learners.
Anki

Brainscape
Brainscape leverages both metacognition and spaced repetition through its Confidence-Based Repetition (CBR) system. Users rate their confidence in each flashcard on a 1-5 scale, and the algorithm uses these ratings to optimize review intervals.
