Is VocaDeck free?
Yes. The browser app is free and needs no account. Your decks and review progress are saved in your own browser.
Which languages can I study?
Built-in starter decks cover Chinese (17 topic decks, 136 words), German (10 topic decks, 80 words), Spanish (10 topic decks, 80 words), Italian (10 topic decks, 80 words), French (10 topic decks, 80 words); Japanese and Vietnamese have smaller starter sets of 24 words each. You can also paste vocabulary for other languages the app lists, such as Korean.
How does the spaced repetition work?
After each card you rate it Not yet, Hard, Got it or Easy. The scheduler then sets the next review: a new card rated Got it returns in 1 day, then after about 2.5, 6 and 16 days at the default ease. A card you miss comes back in 4 hours.
Where is my progress stored?
In your browser on your device. You can export a backup, download your words as CSV, send your library to a second device with a link or QR code, or share a single deck by link. There is no automatic cross-device sync.
