I've tried many many different apps and ways of studying kanji, but this is hands down, without a doubt the single best way I've found to learn all of the 2200 daily use kanji. WaniKani uses a spaced repetition system (SRS) and mnemonics to help you memorize and reinforce the kanji meaning and reading. Along with the kanji, it also teaches you vocabulary in the context of sentences so that what you're learning is easier to remember. This is a paid service but to be honest I think it's worth it's weight in gold. If you are trying to learn kanji I think should be your only resource and I would recommend it to anyone learning Japanese. 🈚🈲🈯🈳🈴🈷️🈵🈸🈶🈺🈹🉐🉑
