Well, my weird study habit is that I use my own app to catalogue the kanji and the words I learn:
This, btw, is a good example of how not to make an app, but anyway, it’s a sticky notes app; this is a page containing radicals. I can click on any radical to see the kanji it’s used in (the ones I’ve added):
Then I can click on the kanji and see its info page
From that I can either go to the radical info page for each radical that make it or to the kanji page of that radical (if the radical itself happens to be a kanji). Or I can see the usage of the kanji
From which I can click to any word I’ve added to see its info page:
From which again I can go to info pages of the kanji that make that word.
Adding those words takes time, but I found that in the long run it does help to have such a quick reference material, at least for me
