Thank you for your interest in my app, MasuDesu (Ver.1)! This version only covers 15 words from the most commonly used honorific expressions you may find in Japanese society. I hope high school to college students who have more than beginner knowledge in Japanese would find this app useful. I also hope users understand that 15 words in this app could not represent the whole system of honorifics since it is much more complicated and somehow evasive. Many Japanese also have difficulties in mastering the usage of proper honorific expressions. They morph depending on the context and the relationship between speaker and listeners, and whom and what you are talking about. I hope I can cover it in more detail at the next version.
Any feedback from you is valuable to me. So, please leave your thought at the review section.
