Free Spaced Repetition Flashcard App for Languages

Fulin Flashcard is a free spaced repetition app for language learners who want a lighter way to remember vocabulary. It runs in the browser, supports Chinese, German, Spanish, Italian, and French, and keeps working offline after your first visit.

Why use spaced repetition flashcards?

Reviewing every vocabulary card in the same order wastes time. Easy words appear too often, while difficult words can disappear until after you’ve forgotten them. Spaced repetition changes the interval for each card based on your recall: difficult words return sooner, while words you remember reliably move further into the future.

That makes a spaced repetition flashcard app especially useful for language learning, where a deck can grow to hundreds or thousands of words. For a plain-language explanation, read how spaced repetition scheduling works.

How Flashcard works

Create a vocabulary deck, reveal each answer, and rate your recall. Flashcard uses those review results to decide when each word should appear again. Over time, your daily session shifts toward the vocabulary that actually needs attention instead of repeatedly testing everything.

You can keep separate decks for different languages, courses, or topics. The focused editor is designed for adding your own vocabulary without turning deck setup into a project of its own. If you’re deciding how quickly to grow a deck, start with 10–20 new flashcards per day and adjust based on the size of your review queue.

Built for language vocabulary

Flashcard supports Chinese, German, Spanish, Italian, and French vocabulary study. It is a good fit when you want your own focused decks instead of a full language course, and when you prefer a browser app over installing and configuring a larger study system.

For learners comparing tools, the Flashcard vs Anki guide explains where a lightweight workflow helps and where Anki’s larger ecosystem still wins.

Who it’s for

Flashcard is for language learners who already have vocabulary they want to remember and need a repeatable daily review habit. That includes beginners building their first topic deck, independent learners collecting words from lessons, and experienced learners maintaining a large vocabulary without reviewing every card every day.

The free flashcard workload calculator estimates the daily review load a new-card rate settles at, which is the decision that determines whether a deck survives its third month.
