Lockademy: Học tiếng Anh

Want to learn English without spending extra time each day? You unlock your phone dozens of times a day—turn each of those times into a short review. Every time you turn on your screen, an English vocabulary flashcard appears: IPA pronunciation, Vietnamese meaning, and an example sentence with translation. Tap to flip the card, then swipe: “already learned” or “review.”

The sole purpose of this app is the lock screen: to display an English vocabulary flashcard every time you turn on your screen. All other screens exist only to set up and track your learning on that lock screen.

What the app includes:

• 10,000 English words sorted by actual usage frequency.

• 6 progressively increasing levels + ABC course (level 0): alphabet and phonics to start from scratch.

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

• Quiz mode: Choose the missing word to complete the example sentence.

• Synonyms and antonyms directly on the flashcards.

• American English TTS audio pronunciation of both words and entire sentences.

• Favorites section to save hard-to-remember words.

• Search and browse all 10,000 words.

• Daily reminders to keep you learning consistently.

• Track your learning progress.
