VocabNinja – Vocab Trainer
Fun Flashcard Language Trainer
Free · Designed for iPad. Not verified for macOS.
Turn your own word lists into motivating practice with three learning modes, daily missions, XP boosters, and optional AI-assisted photo import.
Turn vocabulary learning into a fun daily habit! VocabNinja is the free flashcard app designed for kids and students who want to master new words across any language.
THREE WAYS TO LEARN
Choose the mode that works best for you:
- Multiple Choice – pick the correct translation from several options. Great for quick warm-ups.
- Writing – type the answer yourself to strengthen recall and spelling.
- Flashcards – flip cards and rate yourself. Classic and effective.
Practice in both directions (A→B, B→A, or mixed) and focus on due cards with the smart filter.
SMART REVIEW SCHEDULING
VocabNinja uses a proven spaced repetition system based on the Leitner method. Words you know well come back less often. Words you struggle with appear more frequently. Five review levels ensure every word gets exactly the right amount of practice — no wasted time, no forgotten vocab.
ORGANIZE YOUR WAY
Set up as many languages as you need and structure your vocabulary in folders and boxes. Whether it is English, French, Spanish, or Mandarin — VocabNinja adapts to your school curriculum or personal goals.
STAY MOTIVATED
- Daily and weekly goals – set targets for vocab and lessons.
- Streaks – build a learning streak and keep it going every day.
- Achievements – unlock badges like "First 100", "7-Day Streak", "Perfectionist", and more.
- Error rounds – missed words automatically repeat until you get them right.
LISTEN AND LEARN
Tap the speaker icon to hear any word pronounced out loud. Text-to-speech supports dozens of languages so you can train your ear while studying.
BUILT FOR KIDS AND FAMILIES
VocabNinja is simple enough for young learners and powerful enough for older students. A friendly onboarding lets kids set up their profile, choose a language, and start learning in under a minute. Optional demo data with 50 ready-made vocab items helps beginners dive in immediately.
BACKUP AND TRANSFER
Export your entire collection — languages, folders, boxes, vocab, and progress — to a backup file. Import it on another device or keep it as a safety copy.
