Riki is an Android application developed by Riki Nihongo that aims to help students prepare for the Japanese Language Proficiency Test (JLPT) easily and efficiently. The app offers a comprehensive set of courses from N5 to N1, Business, and Communication. It is designed to be accessible from anywhere, at any time, and on any device.

One of the core features of Riki is its team of expert teachers who are well-versed in JLPT preparation. The app's curriculum is divided into three stages, catering to students at different proficiency levels. The app also offers a range of features such as video lectures, interactive exercises, flashcards, and a free library for non-enrolled students.

Riki Online is an excellent tool for anyone preparing for the JLPT. The app's user-friendly interface and comprehensive curriculum make it an excellent choice for students of all levels. However, the lack of a live teacher may make it difficult for some students to get the personalized support they need. Overall, Riki is a solid choice for anyone looking to prepare for the JLPT in a flexible and accessible way.
