Best Flashcard App for Language Learning (Free and Paid)
The best flashcard app for language learning is one that shows each word in a sentence, lets you hear it, and spaces reviews so words come back right before you'd forget them. Anki is the most flexible free pick, script-specific apps help with Japanese, Korean and Chinese, and for school French or Spanish, cards made from your own class vocab list will beat a random top-1,000 deck.
If your problem is a weekly vocab quiz and a list you keep forgetting by Friday, FlashDeck turns your class list into cards and shows you just the words you're about to lose: Build my study plan.
What a language flashcard app needs
Learning vocab is different from learning bio terms. A word isn't a "fact" you recall once. You need to recognize it, say it, spell it and use it. So a good language flashcard app should have:
- Audio. You can't learn pronunciation from text alone.
- Example sentences. "Comer = to eat" is fine. "Quiero comer tacos" sticks.
- Spaced repetition. Vocab is the textbook use case for spacing. You'll forget new words fast unless you review them on a schedule.
- Both directions. Target language to English, and English to target language. The second is harder and more useful for speaking and writing.
- A daily limit you can actually hit. Burnout kills more language streaks than difficulty does.

Why Anki keeps winning Reddit threads
If you search "best flashcard app for language learning reddit," Anki is in nearly every top comment. It's free on most platforms, has shared decks for most languages and lets you add audio and images. The catch: you're the one designing cards and tuning settings.
Duolingo vs flashcards
Duolingo is great at getting you to show up daily. It's weaker at drilling the specific vocab on your class quiz. Many learners use both: Duolingo for habit, flashcards for the words they actually need.

Best for Japanese, Korean and Chinese scripts
Languages with new scripts need extra steps before vocab even starts.
Japanese
- Learn hiragana and katakana first. Many learners do it in one to two weeks with daily flashcards.
- Then move to kanji with a dedicated tool. WaniKani (paid) and Renshuu (free with paid extras) are popular picks built around Japanese.
- Make cards that show the kanji, the reading and a short example word.
Korean
- Hangul is famously learnable fast, often in a few days. Use flashcards for each letter and its sound.
- Then build vocab cards with the word in a simple sentence.
Chinese
- Pleco is the go-to dictionary app for Chinese learners, with a flashcard add-on.
- Put characters, pinyin with tones, and meaning on separate sides so you test each one.
Best for school French and Spanish
This is where most students in the US, UK and Canada actually are: a French or Spanish class with a weekly vocab list, a unit test and maybe a speaking assessment. In Canada that might be core French; in the UK it might be GCSE French or Spanish.
Here's the problem with big shared decks for school: they're not your list. Your teacher picked 30 words for this unit, and that's what's on the quiz.
How to make school vocab cards that stick
- Use your teacher's list. Copy it straight from the handout or slides.
- Add an article and gender. "la mesa," not "mesa." "le livre," not "livre."
- Add one sentence per word. Short and silly is fine. Silly is memorable.
- Test English to target language. That's how the quiz will ask it.
- Do verb conjugations as separate cards. "Tener, yo" on the front, "tengo" on the back.
The annoying part is the schedule. Which 12 of your 80 words are slipping? You can't tell by vibes, and reviewing all 80 every night wastes time on words you already know.
FlashDeck decides that for you. Paste your vocab list or class notes and it writes one card per word or definition, using only what you pasted. Each day it shows just the cards you're about to forget, about ten minutes. Missed words come back tomorrow; words you know wait a day, then three days, then longer. Build my study plan
How many new words a day?
A common question with no single right answer, but here's a sane starting point:
- School class: whatever your weekly list is, split across 5 days. Thirty words a week is six new words a day.
- Self-study, casual: 5 to 10 new words a day.
- Self-study, intense: 15 to 20 new words a day, if you can keep up with reviews.
The real limit is reviews, not new words. Every new word adds future reviews. If your daily review pile starts taking more than 20 minutes, pause new words for a few days. Using the best flashcard app for language learning doesn't help if you burn out by week two.

FAQ
What is the best free flashcard app for language learning?
Anki is the most powerful free option on desktop and Android. Quizlet, Memrise and Duolingo also have free tiers, and paper flashcards cost almost nothing.
What flashcard app does Reddit recommend for language learning?
Anki is the most common answer in Reddit threads about language learning, usually paired with a course or textbook. Language-specific tools like WaniKani for kanji and Pleco for Chinese come up often too.
Is Duolingo enough to learn vocabulary?
Duolingo is good for building a daily habit and basic exposure. For specific vocab, like the words on your class test, flashcards made from your list are more targeted.
How many flashcards should I learn a day for a language?
Start with 5 to 10 new words a day and adjust based on how long your reviews take. If reviews take longer than about 20 minutes, slow down on new words.
Should flashcards go English to target language or the other way?
Do both if you can. Target-to-English builds recognition for reading and listening, while English-to-target builds the recall you need for speaking, writing and most vocab quizzes.
