Spaced repetition is a study technique that schedules reviews right before you're likely to forget something. Cards you know well are shown less often; cards you struggle with come back sooner. It's the same underlying method Anki popularized, and the one Decks uses.
Yes — you get 20 new cards a day by default and 50 reviews a day on the free plan, enough for most study routines. Premium removes the review limit entirely, for heavier study loads.
No. Decks works immediately with anonymous login — you can start studying without creating an account, and add one later from Settings if you want to sync across devices.
Yes — unlimited decks and cards on any subject, alongside the curated language decks.
Decks ships curated decks for Japanese, Chinese, Spanish, and French, covering everything from writing systems (hiragana, katakana) to grammar (HSK, Tae Kim's guide) to vocabulary and full sentences. You can also build decks for any other language or subject.
