## A real Japanese dictionary on your device

Vocabulary, kanji, readings, conjugations, components. The whole thing, downloaded once and yours offline. Behind every word in every translation.

_The data_

## Built on the dictionaries the Japanese-learning world already trusts

The dictionary draws on JMdict for vocabulary, JMnedict for names, KANJIDIC for kanji data, and Kanji Alive for component information. These are the open Japanese-language resources behind most serious dictionaries on any platform. They live on your device, indexed for fast search.

### JMdict

Vocabulary entries.

### JMnedict

Proper names.

### KANJIDIC

Kanji data.

### Kanji Alive

Components and breakdown.

### The entry view — Thousands of words, in depth

Every entry has Meanings and Grammar as peer tabs. Meanings shows the definitions, parts of speech, JLPT and grade tags, and the kanji that make up the word. Grammar shows the conjugation table with audio on every form.

Open it from search, from your saved word lists, or by tapping any word inside a translation. A lighter quick-access version pops up inline when you tap a word in context, with the full entry one tap further.

### The kanji drill — Pull any kanji apart

Tap a kanji and see what it's made of. Components, similar kanji, JLPT level, grade, stroke count, frequency rank. On'yomi and kun'yomi readings, each with audio.

### The conjugation table — Every form of every verb, with audio

Open the Grammar tab on any verb and see the full conjugation table. Past, negative, te-form, causative, polite, polite past, with audio on every row.

Listen to a form until it sounds right. Then move on.

## Sharper search, better recall

### Filters — Search at your level

Filter results by JLPT level (N5 to N1) or by frequency rank. Useful when you want to stay within the vocabulary you're actually studying. Filters need the full dictionary download.

### History — Your fifty most recent searches

Search history keeps your last fifty lookups, so you can come back to anything you've checked recently. For words you want to keep for longer, add them to a word list.

Word lists are custom collections you build from any dictionary entry.

### Word lists — Your own collections, however you want them

Build custom collections from any dictionary entry. A list for things you keep forgetting, a list for words from a book you're reading, a list for whatever you want. Lists are accessible from the home screen, and live alongside everything else on your device.

_Two sizes_

## Lite or full, both work offline

### Lite

_Around 20 MB_

A compact but useful subset of the full dictionary. Vocabulary, kanji breakdowns, conjugations, search. Designed to get you started quickly without a long download.

### Full

_Around 400 MB_

Everything in Lite, plus JLPT and frequency filters, similar kanji, kanji components, and the complete entry set.

## Quick answers

### Does the dictionary work offline?

Yes. Once installed, every search, kanji breakdown, and conjugation lookup runs locally. No network needed.

### Where does the data come from?

JMdict, JMnedict, KANJIDIC, and Kanji Alive. All open Japanese-language resources, credited and respected.

### Why is there a Lite version?

So you can start using the app quickly, on a small download, without giving up the parts of the dictionary that matter most day to day. Upgrade to the full dictionary when you're ready.

### How do conjugations get audio?

The offline pronunciation voice is built in and handles every form. If you want a higher-quality voice, connect a provider in settings.
