There's no shortage of Japanese-learning apps. Some are great for vocabulary, some for kanji, some for casual practice — and many JLPT candidates end up juggling four or five of them, each covering one piece of the exam. Before you commit time (and possibly money) to an app for JLPT preparation, it's worth knowing which features actually move your score. Here's a practical checklist.
For a broader look at books, practice tests and other resources, see how to build your JLPT study stack. This post focuses on apps specifically.
1. Coverage of every exam section
The JLPT tests vocabulary, kanji, grammar, reading and listening. An app that only does flashcards covers one slice. That's fine as a supplement, but if it's your main tool, you'll have blind spots — and the JLPT's sectional minimum scores mean one weak section can fail the whole exam (see how JLPT scoring works).
Check: does it include reading passages and listening audio, not just vocabulary and grammar drills?
2. Questions that match the real exam format
Practising with questions that look nothing like the JLPT builds knowledge, but not exam skill. JLPT questions have specific formats — kanji reading, contextual vocabulary, sentence ordering, grammar in passages, and several types of listening questions.
Check: are the question types modelled on the official JLPT structure for your level?
3. Full, timed mock exams
Section-by-section practice can't show you how you perform across a full exam under time pressure — whether you run out of time on reading, or how fatigue affects listening. Full mock exams under real timing are essential in the final months.
Check: can you take a full-length mock exam that's timed and scored like the real thing, without seeing answers as you go?
4. Explanations for every answer
An app that only tells you "correct" or "incorrect" leaves you guessing about why. The real learning happens in the explanation — especially for grammar questions where two options look similar. Ideally, explanations are available even for questions you got right, since a correct guess hides a gap.
Check: does every question have an explanation, and does it explain why the wrong options are wrong?
5. Explanations in your language
If English isn't your first language, explanations in English add an extra layer of translation. Learners whose first language is Chinese, Korean or Vietnamese often understand nuance far faster when it's explained in their own language — see why studying in your native language helps.
Check: what languages are explanations and lessons available in — and is it the whole app, or just a few menu labels?
6. Structured lessons, not just questions
Questions test what you know; lessons teach what you don't. An app that only quizzes you assumes you're learning the material somewhere else. For most learners, having grammar, kanji and vocabulary lessons organized in a sensible order — and linked to the questions that test them — saves a lot of time.
Check: can you learn a grammar point and then immediately practise questions on it?
7. A study plan that adapts to you
A fixed "Day 1, Day 2" schedule breaks the first time life gets busy. A useful study plan adapts to how much time you actually have, tracks what you've already covered, and paces you toward your exam date.
Check: can you set your study days and session length? Does the plan adjust when you fall behind or get ahead? Does it account for your exam date?
8. Progress you can see
Motivation matters over months of preparation. Streaks, activity history, and a clear "what's next" reduce the friction of starting each session. For more on building the habit itself, see how to build a daily study routine.
Check: can you see at a glance where you stand and what to study next?
Red flags to watch for
- Unrealistic promises like guaranteed passes or "fluent in 30 days".
- Content that doesn't match your level, or levels that aren't clearly separated.
- Copied or suspicious "real exam" questions. Actual JLPT questions aren't freely redistributed; good apps write original questions in the exam's format.
- No way to try before paying. You should be able to judge the content quality before committing.
How JLPT Ready measures up
We built JLPT Ready because preparing for the JLPT shouldn't require five separate subscriptions. Here's how it maps onto the checklist:
- All sections, all levels: grammar, vocabulary, kanji, reading and listening for N5 through N1.
- Exam-format practice: the Dojo's questions follow the official JLPT section structure and timing for each level.
- Full mock exams: Real Exam mode is timed, blind, and scored like the official exam structure; Practice mode removes the pressure.
- Explanations for every question: AI explanations on every question, not only the ones you miss.
- Your language: the whole app works in English, Japanese, Korean, Vietnamese, Simplified Chinese and Traditional Chinese — explanations included.
- Structured lessons: the Learn section organizes grammar, kanji and vocabulary by chapter, linking items to the practice questions that test them.
- Adaptive study plan: set your study days and minutes per session, and get a day-by-day schedule built from what you have left, with deadline pacing once you set an exam date.
- Progress dashboard: streak, activity calendar, and your next recommended session in one place.
You can try it before paying: N5 is free with no card required, and the pricing page lists what each plan includes. For the full preparation framework that any tool should support, see the complete JLPT preparation guide.
The takeaway
The best JLPT app covers every section, mirrors the real exam format, offers timed mock exams, explains every answer in a language you think in, teaches as well as tests, and plans around your actual schedule. Use this checklist to evaluate any tool you're considering. If you'd like to see how JLPT Ready fits, you can start free with N5 — no card required.
