Give it a spin and let me know your thoughts! Best of luck this weekend! 🎌

Hi everyone,

I’m looking for feedback on a mobile JLPT practice tool focused specifically on exam-style practice, not general Japanese learning.

The current release supports N5, N4, and N3 practice, plus 3 full-length N3 mock exams. N4 and N5 mock exams are still being prepared because the review process takes time, and I don’t want to rush low-quality test papers just to make the app look bigger.

I’m mostly looking for feedback from people who are currently preparing for the JLPT or have recently taken it. (I'll share the link/name below, but I wanted the focus to be on the tool itself first.)

FAQ

Q0: Why build another JLPT app?

Because when I was studying for N5, my practice setup felt too fragmented.

I often had a JLPT question on one side and a dictionary or AI tool on the other, just to understand things like: “Why is this answer wrong?”, “What does this grammar point really mean here?”, or “Why does this sentence feel different from the translation?”

Another issue was language friction. Many explanations online are only in English. I’m a Turkish speaker, and Japanese grammar often maps more naturally to Turkish than to English, so going Japanese → English → Turkish made studying feel unnecessarily indirect. I wanted explanations and translations to be available in multiple languages, not only English.

Listening practice was another pain point. Sometimes I could hear parts of the audio, but not understand the full sentence clearly. Many resources didn’t give me transcripts, translations, or detailed breakdowns, so I kept using separate AI tools just to analyze what I had heard.

So the idea became: keep the whole JLPT practice loop in one place.

Solve a question, see why the answer is right or wrong, read a detailed explanation, check the transcript or translation when needed, ask a follow-up question if you're still confused, and bring weak questions back through review.

That is also why the app includes things like level-based kanji with images and example sentences, quick drills for numbers and counters, timed mock tests, mistake review, and SRS-style repetition for practice questions themselves.

It is not meant to replace textbooks, teachers, or Anki. I built it because I wanted JLPT practice to feel less like constantly switching between tools, and more like one focused study workflow.

Q1: Is this a Japanese course?

No.

It is not meant to replace Genki, Minna no Nihongo, Anki, WaniKani, a class, or a real teacher.

The focus is narrower: JLPT-style exam practice, especially question formats that are awkward to practice with static PDFs, plus supporting study tools that many learners need during JLPT preparation, such as JLPT-level vocabulary, JLPT-level kanji, Japanese counters, and (planned on the roadmap) conjugation practice.

Q2: Are these questions/explanations AI-generated?

The core questions, answers, and explanations are manually reviewed by a JLPT instructor before release, because raw AI output isn't reliable enough for language learning. I do use AI to assist my own workflow (drafting, organizing, automation) to save time, and there is an optional in-app AI assistant if you want to ask follow-up questions in your native language. There is also a report button on every practice screen, because even reviewed content can still have mistakes.

Q3: What kind of practice does it have? Is it just multiple choice?

No, it is not only standard multiple choice.

The app includes:

• All major JLPT-style question types: Vocabulary, Reading, Grammar, and Listening
• Detailed explanations for all question types, with optional AI assistance available in English, French, German, Spanish, Korean, and Turkish
• Listening questions with transcript and translations
• Extra small practice modules, such as Japanese counters, numbers, and other quick drills
• Beginner-friendly Kana SRS practice, plus level-based Kanji study with sample sentences and visual image support
• SRS-powered review for vocabulary and weak questions

The goal is to make JLPT practice feel more interactive on mobile, instead of just reading a PDF and checking an answer key.

Q4: Does it have spaced repetition? Why not just use Anki?

Anki is great and this isn't trying to replace it.

The difference is the workflow. This is focused on JLPT-style questions, audio, explanations, and mistake review in one place. Vocabulary modules use spaced repetition, and the app tracks weak questions so they can come back in future drills.

If you already have a strong Anki setup and only need flashcards, you may not need this.

Q5: Can I use this to learn Japanese from scratch?

Not really.

This is not a replacement for a structured beginner course.

That said, there are foundation modules for Hiragana, Katakana, and Kanji. The Kanji section includes things like sample sentences, visual support, but the main purpose of the app is still JLPT practice.

Q6: Is the app English-only?

No.

The app supports multiple explanation/translation languages: English, French, German, Spanish, Korean, and Turkish.

This is important because many JLPT learners are not native English speakers, and studying Japanese through English can become an extra layer of friction.

Q7: Does the app support speaking or pronunciation practice?

JLPT does not test speaking, so this is not the main focus.

There is an experimental voice-based vocabulary recall feature for N5, mostly as an active recall / motivation tool. It is still beta, so I’d be especially interested in feedback on whether it handles different accents well.

Q8: What is the Quick Practices section?

It is an experimental area for small practice modules that don’t fit neatly into the normal JLPT exam flow.

Right now it includes focused drills like numbers, counters, and similar quick-practice topics. I’d like to expand it based on actual learner feedback — for example, verb conjugations, particle drills, kanji handwriting, speed listening, or other annoying weak points people want to train directly.

Q9: Does the app work offline?

No, not fully.

The app currently requires an internet connection because explanations, translations, audio, and some support features are served dynamically. I know offline support would be useful, but for now I’m prioritizing content quality and keeping the app size manageable.

Q10: What is the pricing model? Is the free tier limited?

Full access requires a subscription, but there is a free tier to try it out. I’ve tried to keep pricing reasonable and localized by region, rather than using one flat global price. I know subscriptions aren't everyone's favorite, so I want to be upfront about it.

I’d really appreciate honest feedback on the screenshots/video and on the idea itself.

Especially:

• Do the practice formats look useful for JLPT prep?
• Are the explanations the kind of thing you would actually read after a mistake?
• Does anything look confusing, unnecessary, or suspicious?
• What practice mode would you want added next?

Thanks.
