Decky is a word-of-the-day app built on flashcards and spaced repetition. A two-minute placement test sets your level from A1 to C2, then a short daily deck brings each Spanish word back just before you'd forget it.

What it's for

A daily Spanish habit

A short deck each day at your level: a few minutes, then you're done.

Remember words for good

Spaced repetition brings each word back just before you'd forget it.

Learn words in context

AI example sentences show each word inside a real phrase, and every word is read aloud.

Practise pronunciation

Say the word out loud and your phone checks whether you said it right.

How it works

  1. Take the two-minute placement test (A1 to C2).
  2. Study today's deck: learning cards first, then overdue reviews, then new words.
  3. Answer each card; Decky schedules when the word comes back.
  4. Reach 60% mastery of a level and words from the next one join your deck.

Frequently asked questions

How does Decky help me remember words?

Decky uses spaced repetition. A word you get right comes back later; a word you miss comes back sooner. The daily deck puts learning cards first, then overdue reviews, then new words, so your time goes to the words you're about to forget.

What level is it for?

Any level from A1 to C2. A two-minute placement test sets your starting level, and you can retake it any time. When you reach 60% mastery of a level, words from the next level start joining your deck on their own.

Which languages does it teach?

For English speakers, Decky teaches Spanish, with meanings in English. For speakers of other languages it teaches English, with meanings in English, Spanish or Turkish. The app itself is in English or Spanish.

Is it free?

Decky is free to download on Google Play. The free version gives you 15 new words and 60 reviews a day. Premium raises that to 50 new words and 300 reviews and adds every voice, accent and background. It's a monthly or yearly subscription, and the yearly plan starts with a 3-day free trial.

Is there an iPhone version?

Not yet. Decky is available on Google Play for Android phones.

Do I need an account, and what data does it keep?

No account is needed. Decky creates an anonymous identifier and stores your learning progress and settings on our servers so your daily deck can be prepared, which is why building the deck needs an internet connection. It shows no ads. Pronunciation is checked by your phone's own speech recognition, and Decky doesn't receive your voice. The Decky section of our privacy policy has the details.
