About this app

JDict is a Japanese-English offline dictionary featuring over 160000 entries, over 10000 kanji and almost 60000 example sentences.
It is largely inspired by well-known "[Imi_wa?]" dictionary for [i_O_S] platform both functionally and visually.

Current features:
- works offline
- shows kana/romaji as you type
- supports wildcards in vocabulary
- recent words, examples and kanji
- romaji mode in search
- kanji search is divided by ON/KUN readings, Nanori and meaning results
- very fast example search
- extract words from sentences feature
- kanji stroke order animations
- furigana is matched everywhere with my own algorithm (still can have some bugs though)
- in component view, you can see all kanji with given component ordered by JLPT level and word commonness
- in kanji view, you can see all compounds with given kanji ordered like above
- search kanji by components (design inspired by "Japanese" dictionary)
- browse kanji by JLPT and School Grades
- notes
- lists (works like favorites but with folders/sub-folders)
- vocabulary search recognizes some basic grammar when typing
- in word detail view examples are categorized by word meaning if such a connection exists

As you can see features are mostly basic for now.
The database file is quite big (~230MB). The reason for that is that it contains a lot of example sentences data and needs a lot of indexes to run smooth.

My plans:

- make the application more user-friendly (list search)
- learn vocabulary feature (using lists)
- exporting lists to Anki
- external links in vocabulary
- kanji handwriting recognition
- Shiratori game
- improve extract words algorithm (I have some ideas using the statistical approach to make it run faster)

Ratings and reviews

I've used the free version of this app for over a year now and have always liked it. watching an ad or two was worth the value of using it for an hour or so. however, recently, the ads have increased 1,000,000% to the point where every word you look up or kanji decomposition, you click you're hit with another 30-45sec ad. it's gotten so annoying that, sadly, I will be uninstalling it and looking for another to replace it. I would've given it a 4 out of 5 before, but now it's more like a 1.

This app used to be amazing. It saved me a lot of time back in Japanese 1 and 2 when I was in high school. This app now contains really annoying intrusive ads for Facebook where it used to contain banner ads that were out of the way. I tried upgrading only for it to say it failed to process it in the app while still taking my money. This is a perfect example of fixing things that aren't broken. The ads were fine before, but you "fixed" them and they now cover the whole screen at random. 2/5

the recently updated pushing of apps on the free version are unbearable used for a few minutes and got like an unskippable 1 or 2 minute candy crush ad, this is happening very often. barely usable now
