User Reviews

Overall, users praise Japanese Grammar: Coban for solid grammar explanations, structured lessons, and responsive development, making it a strong tool for learners from beginner to advanced. The main drawbacks cited across multiple reviews are reliability and UX: frequent crashes and freezes, ads interrupting study, translation and vocabulary prompts that aren’t always clear, and some UI/drag-and-drop glitches or tablet compatibility concerns. The subscription pricing is also a point of contention. Despite these issues, many call it one of the best resources for Japanese grammar practice.

Pros

Thorough grammar explanations with examples and exercises that aid learning.
Active developer updates and quick responses to user feedback.
Well-organized, easy-to-navigate interface.
Suitable for learners from beginner to advanced with solid foundational content.
Engaging bite-size lessons and quizzes for daily practice.

Cons

Crashes and freezes, sometimes not saving progress.
Ad interruptions that block access to content and navigation.
Translations can be wonky and vocabulary prompts unclear.
Subscription model may deter some users (no lifetime option).
UI/UX issues and device compatibility (drag-and-drop glitches, stutters; tablet support concerns).

Recent reviews

The new update makes it very laggy when scrolling up to the top selector for selecting what you want to study (ie grammar, vocab, kanji). It makes the site slightly annoying to use. Overall though, I love the content in the new update, the only thing stopping me from getting the premium upgrade is the lagging (You can still learn up to JLPT 3 for free.) it’s still a very good source to use, it has just become slightly annoying.

I’m going to be taking the N3 this December and I was struggling with finding an app that had good grammar practice. The textbooks are a lot and can get boring easily, but so far i’ve learned a lot from this app in my 2 days using it, and it’s rlly fun, and the developer is super nice. I submitted a feature request and they got back to me in less than 24 hours.
