Vietnamese is a beautiful but tricky language to master. With six tones and plenty of new vocabulary, memorizing words isn’t always straightforward. Flashcards are one of the most effective tools for building long-term vocabulary — but not all flashcard apps are designed with tonal languages like Vietnamese in mind.

Some apps don’t handle diacritics well, others feel clunky, and many don’t make it easy to hear words pronounced correctly.

To save you time, we’ve rounded up the best flashcard apps for Vietnamese learners in 2025.

1. Mora — Best for Vietnamese and Tonal Languages

Mora is a modern, lightweight flashcard app created specifically for language learners who need more than just plain text cards. It’s especially useful for tonal languages like Vietnamese, where listening and pronunciation are just as important as memorizing spelling.

Key features:

• ✍️ Handwriting input — jot down characters or create your own phonetic spelling when typing special diacritics feels cumbersome.
• 🔊 Audio output (text-to-speech) — hear how words sound instantly, crucial for practicing tones.
• 🔁 Spaced repetition — reviews are optimized so you don’t waste time, helping you retain words long-term.
• 📂 Import & export via CSV — upload your own word lists or export your decks for safekeeping.
• 📝 Examples & notes field — add grammar notes, example sentences, or cultural context.

Why it’s great for Vietnamese: Mora was built by a language learner frustrated with existing flashcard apps. It combines simplicity with features tailored to tonal languages, making it easy to practice Vietnamese vocabulary consistently.

2. Anki — Best for Customization

Anki is one of the most powerful flashcard apps available. With thousands of community decks (including many for Vietnamese), it’s a popular choice among serious learners.

Key features:

• Advanced customization for card design and scheduling.
• Large library of shared Vietnamese decks.
• Syncs across devices.

Downsides for Vietnamese learners: The interface is outdated and can feel overwhelming. Setting up tones, audio, or diacritic-friendly input may require add-ons. Best suited for learners who don’t mind tinkering.

3. Quizlet — Best for Ready-Made Decks

Quizlet is popular with students worldwide and has a big selection of pre-made Vietnamese decks.

Key features:

• Easy-to-use interface.
• Community-created decks.
• Variety of practice modes and quizzes.

Downsides: Spaced repetition is limited in the free version, and the app isn’t specifically tailored to tonal languages like Vietnamese.

4. Memrise — Best for Gamified Learning

Memrise blends flashcards with gamification and video content. There are Vietnamese decks available, and it can be motivating for casual learners.

Key features:

• Native speaker video clips.
• Gamified learning experience.
• Plenty of ready-to-use decks.

Downsides: The platform has moved toward being a broader language app rather than a focused flashcard tool. Some learners may find it distracting compared to simpler alternatives.

Which App Should You Choose?

• If you’re starting out with Vietnamese → Mora is the best balance of ease-of-use and tonal language support.
• If you love customization → Go with Anki, but expect a learning curve.
• If you want pre-made decks → Try Quizlet.
• If you like gamified learning → Memrise could be a good fit.

Consistency matters most — and for many Vietnamese learners, Mora makes flashcard study simple, effective, and tailored to tonal languages.
