Japanese Dictionary with Grammar takes the pain out of looking up words in a language you're still just learning.

With most dictionaries you need to know the root word before you can find the word you're looking for. Which is great if you've been studying for 10 years already. But one of the most frustrating things when you are a beginner is that you don't know enough grammar to work out what the root word is. So you can't look it up.

Japanese Dictionary with Grammar has a built in reversing grammar engine. It takes care of all that for you. It understands Japanese grammar rules so you only need to enter the word as it is - and the dictionary works out the root word for you and then looks it up. Fast.

For example:
Search for たべられる (taberareru) in most dictionaries and you won't find anything. Search for it using AI Japanese Dictionary and it will tell you that this is the "Able to Do" form of たべる (taberu), "(v1,vt) to eat".
Go further and search for たべられない (taberarenai) and find it is the "Regular Negative of the Able to Do" form of たべる (taberu).
Or even further and search for たべられなかった (taberarenakatta) and find this is the "Past tense of the Regular Negative of the Able to Do form" of たべる (taberu).

The grammar smarts also understands adjectives, so it knows that おいしくなかった (oishikunakatta) is the past tense of the negative of おいしい (oishii), (adj) delicious.

Beginners often mis-hear or mis-remember words. So this dictionary also has "Deep Search" to take care of that for you. It looks for other similar spellings for your search and lists them as alternate suggestions.
Search for きぷ (kipu) by mistake and Deep Search will also find きっぷ (kippu), and ぎふ (gifu), and several other words which might be the one you're actually looking for.

Of course you can search for romaji, hiragana, katakana, English, kanji...
It's also smart enough to look for katakana if you put in hiragana by mistake (or the other way around). So even though you searched for べっど (beddo) it finds ベッド (beddo), (n) bed.

If you remember one or two kanji from a word, but not the whole thing, then just put "?" for the ones you don't know and the dictionary will find all the possible words that match.

The dictionary includes over 200,000 words from the famous Monash University EDICT dictionary, and it doesn't store all the alternatives, it works them out on the fly, so the whole app is smaller and no internet access is required.

Finally. Using a Japanese dictionary just got a whole lot less frustrating.

It’s very good for what it does but it would be more useful as an iPhone/iPad app. Also, beginners would appreciate having an option to spell the Japanese words out in Romaji.

Do not have Back/Forward buttons

The content is acceptable and it is fast. However there is a major lack of basic functions.

There is no History or Back/Forward buttons.
So when you want to go back and forth to look at words you entered, you have to type or paste the words again! Every. Single. Time.

You see that word-wrapping function they added in February 2019? I requested that. Before the word wrapping, even if you opened the window to fill your screen, words went off the right side and could not be viewed because there is no horizontal scroll bar. A major oversight.

And then I quickly encountered the lack of Back/Forward buttons.

I sent a message, twice, to Dependency imploring them to add Back/Forward buttons. They said they don't have any plans to do that.

Good app but...

I like how you can look up any form of a word. That is very useful and convenient. The app does have a slgiht problem, though. Every time I close out of the app, I cannot pull up a new window without first quitting the app, which can get frustrating. Please fix this, then the app will be perfect.
