User reviews

Great app

I checked whether the examples were actually used by native Japanese speakers, and I found that the example sentences were well-constructed and the explanations very clear. I also felt that it provided a solid understanding of the grammar required for the Japanese Language Proficiency Test. I think this would be excellent for people from overseas planning to move to Japan in the future, and I believe companies could also make use of it. I feel this represents a new style of learning:)
