Simple yet effective
This is one of my favorite apps for learning Japanese (and believe me, I’ve tried a lot or them)! There’s a ton of value with the free version, but the paid version is like $3 and you get puzzles with vocab, not only sorted by level (N5, N4, etc), but also by textbook (and further sorted by chapter!) The crossword format is a novel concept and makes it fun to do vocabulary drills. If you can’t tell already, I highly recommend this app for anyone learning Japanese, and especially for those learning via the popular textbooks! 👏
