About this app

WordStack helps you learn English words every day in just 10-15 minutes, with no sign-up and no internet required.

📚 LESSONS FROM A1 TO C2
Take a quick placement test and the app picks your English level. Each lesson has 25 words with transcription, an example and pronunciation. Flashcards first, then a quiz, so the words really stick.

🔁 SMART REVIEW
Words you get wrong go straight to review. Three kinds of exercises (choose the translation, choose the word, type the word) help you master every word. There's also a separate mode for your hardest words.

✍️ YOUR OWN WORDS
Add words from movies, books or work. The translation, transcription and example are filled in automatically. Import a whole list from text or a file and review it together with your lessons.

🌐 TRANSLATOR
The built-in word and phrase translator works offline, and when you're online it shows translation options from Wiktionary.
