It uses their own homebrew of radicals, mnemonics, space repetition system, and a kanji ordering that allows you to learn much more quickly and effectively compared to the traditional methods. At least it's working very well for me.
Most kanji learning is broken and inefficient. They want to fix that.
It is possible to try out the first three levels completely free of charge.
Pros:Very intuitive and simple to use. It is helping me a lot on learning Japanese.
Cons:No official mobile app. However there's a non official one that does the job.
