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

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 dictionary itself is very good. However, I paid for the ad-free "premium" version of this app and it is no different from the free version. It is still clogged up with ads which are getting longer and longer. I'm not sure if this is a glitch or a scam. Message to developer: Please can you update the app to fix this? In the meantime I suggest users should not pay for the ad free version.

The popup ads have always been obnoxious: loud and fullscreen. However, they were manageable because they only came up once per session. Now, however, the ads show up EVERY FEW SECONDS and are extremely long. The app is now unusable and will prevent new users from tolerating the ads long enough to see that the dictionary and interface are very good (though the example sentences are useless). I also bought premium and am still seeing ads. THIS IS A HUGE PROBLEM.

What’s new

Fixed errors on devices with low RAM capacity and added a feature for Japanese alphabet reading with audio support, along with a practice exercise screen.
