Hundred words chop, scallop, words without memorization, music words, Magoosh, little red book, etc. It's all used.
Hundred-character chop: it is more vivid with pictures and fonts. But it will lead to the embarrassing situation that the picture corresponds to the text and the text does not correspond to the Chinese meaning. And the next day, you must review the words recited on the first day before you can recite new words. It is very difficult for me to recite 100 every day, because I have to review 100 and recite 100 the next day, because the new words on the first day will be forgotten to some extent, and the next day is equivalent to memorizing 100+ new words.
Scallop: You can only see one meaning at a time. It is better to review words and have spelling patterns, so that you can master words more deeply. At first, I didn't know what this meant. It will take time to use this, and the words will be reviewed many times. There are fewer new words a day, which is not suitable for people who brush a lot of words.
Don't recite words: examples are based on movie lines, which may be more attractive to some people, but others are just so-so.
Music words: an app developed by New Oriental, which can open words to see words and meanings, display root affixes and meanings, and recite them firmly through etymology. A group of 8 words, recite 8 words and review it again, which is also easy to review. The example level is average. You can see the mnemonic method of netizens, the associative mnemonic method of learning from netizens' contributions when etymology is difficult to remember, and so on.
Magoosh: Example sentences are the original questions of the exam. Reciting examples will make you feel familiar. But Ying Ying's recitation is more difficult for people with poor foundation.
Recite the little red book, pick out all the words you don't know, copy 100 times to eliminate the fear of new words, and then recite them repeatedly according to the etymology. This kind of recitation is suitable for reciting a large number of words in a short time, and reciting 1000 words a day.
To sum up, I personally suggest that you choose 1-2 for your own app and word book. Don't need too many words every day. When you use them at the same time, you will often encounter cross words, and your impression will deepen, so it is not difficult to recite and review.
