About this app

Want to learn English without taking extra time out of your day? You unlock your phone dozens of times a day: turn each one into a micro-review. Every time you turn on the screen, a card appears with an English word: the pronunciation in IPA, the meaning in Portuguese, and an example sentence with translation. Tap to reveal and swipe: "I know it" or "again".

The sole purpose of this app is the lock screen: it shows an English vocabulary card every time you turn on the screen. All other screens exist solely to configure and track this learning experience on the lock screen.

What's inside:
• 10,000 English words ordered by actual frequency of use.

• 6 progressive levels + ABC course (level 0): alphabet and phonetics to start from scratch.

• Spaced repetition (Leitner system): each word comes back just when you were about to forget it.

• Multiple choice quiz mode: complete the gap in the example sentence.

• Synonyms and antonyms in quick flashcards.

• US English TTS voice that pronounces the word and the entire phrase.

• Favorites to save words that just won't stick.

• Search and browse through 10,000 words.

• Daily reminders to keep you on track.

• Statistics of your progress.

100% offline after installation: no internet required, no account needed, and the developer does not collect your data.

Free with ads. Prefer to study without them? A one-time purchase removes ads forever.
