I am learning one deck/day!! Clear definition with good examples! It goes back to words that you don’t know or forget that makes learning very efficient. It would be even better if there were a list for every deck that users can refer to.
As a voca app, this one is very impressive. I hope to see more words and even verbal practice in the app.
1. Pronunciation. It's important to know the pronunciation, which also helps memorizing the words.
2. Two options should be placed in front. That is,"I know this word" and "I don't know this word" should be placed on the new word side, instead of on the explanation side. Sometimes I intuitively click on "know this word" after seeing the explanation of a completely new word, which is then marked as "mastered". Then it rarely appears in the learning process.
3. Reverse (undo). This is related to the second issue. Sometimes I accidentally click on a wrong button, and the word is marked as "mastered". I hope that I would be able to reverse back to the previous word and select the right option.
