Aptenyo JLPT Grammar N5–N1

Aptenyo 文法 is a JLPT grammar app: 754 sentence patterns from N5 to N1, one card for each. Unlike a grammar book you only read, every pattern comes with a scene illustration and the number of times it has been tested since 2010. Read it, then practice it, and the questions you miss come back for review. No sign-up or ads. N5 is free. N4–N1: 7-day free trial, ends automatically with no charge. Buy once later if you choose; no subscription.

Past-exam appearance counts are compiled independently from the app’s collected examples. They are not official JLPT statistics and do not predict future questions.

Search grammar patterns directly or sort by their past exam appearance counts. Auto-advancing cards work in portrait or landscape.

【One card per pattern】

Every pattern has its own grammar card: • Connection: what form comes before the pattern • When to use it: meaning and feel, with the limits spelled out • Example sentences: 1–3 per pattern, with a scene illustration and Japanese audio • ○ / × contrast: a mistake learners really make, the correction and why • Similar expressions: up to three, each with one line on how it differs • Logic diagram: see the structure of the pattern at a glance

【Tested N times since 2010】

Each pattern is marked “Tested N times since 2010”, based on grammar statistics from past exam questions. It is a count of what has already happened, not a prediction. Patterns without data show “No data”. Export Favorites as a PDF sorted by exam frequency, with frequency counts.

【Practice with real exam question types, then put what you read to use】

Practice the three JLPT grammar question types: ・文法形式の判断 (four-choice grammar questions) ・文の組み立て (sentence ordering) ・文章の文法 (passage fill-in-the-blank) Plus extra multiple-choice practice with confusable patterns.

【Explanations for every mistake】

When you get one wrong, the app shows where it went wrong, the clue in the question and the correct answer, with the full sentence, its translation and audio. Expand to see why each choice is right or wrong; correct answers have explanations too. Missed questions go to your Mistakes list and come back on a spaced-review schedule, so you can redo them.

【Look-alike or mean-alike? Compare side by side】
