With OniKanji, learning vocabulary alongside each kanji has really helped solidify the meanings and readings in my head, such that I'm seeing noticeable differences in my reading speed and comprehension. Running into vocabulary learned through OniKanji while reading is very rewarding. That combined with the immersion features makes this an app I use daily for my Japanese studies.
