The best app for anyone studying Japanese!
I’ve used this app for many years and it’s by far the best. You can look up any word, even slang, instantly add it to custom lists or highlight it and then use the flash card study function to study. It’s very easy to use, you can search kanji by handwriting, SKIP or using bushu, which I found the best way to study similar looking or same compound kanji together. It’s also great for JLPT since there is in build vocab and kanji lists for each level.
The negative is that if you search a word in english, you will get so many results of common as well as obscure words that even my Japanese friends have never heard of. It would be great if they added some kind of information regarding the commonness of the word or how often it appears.
