I used hundreds of words, pen and ink, rubbings. I can tell you how I feel.
I know how to chop a hundred words by watching mint, mainly by memorizing words with pictures. It's interesting, but it's not for me. My attention will be distracted. Some pictures are also quite strange, and it is not easy to remember the meaning through pictures. However, I like its surroundings.
Ink and ink recite words, it can choose the words to recite by itself, as well as forgetting curve analysis. It's not bad to recite words simply, but there is a limit to reciting words, and it's annoying to have to do tasks or pay money to continue reciting them.
Tuo is also a software that simply recites words. I like its interface very much. It's simple. There are no messy advertisements. You can set your own concentration time, which is quite addictive. I use this to test CET-4 and CET-6.
Memorizing words mainly depends on your own persistence, and software is also an aid. Just find the one that suits you best
