Vocab++

Vocab Plus is the best app for learning English vocabulary. It is designed to help you efficiently learn English vocabulary.
1. You are going to learn English vocabulary in English instead of your native language.
2. The words in this app are categorized by CEFR levels. It describes language ability on a six-point scale, from A1 for beginners to C2 for those who have mastered a language.
3. You need to recall and review the words repeatedly after learning. We use a spaced repetition algorithm to help you manage the process.
