Hi Andy,
I've just mentioned the name of that app above, and also several times earlier in this thread.
I recommend the iOS app
Lingvo. Its price is symbolic, and it works on both iPad and iPhone. It's from the makers of FineReader, which probably you know is the best currently available OCR software.
Of course, it depends on exactly what languages (and language pairs) you are interested in, but for my (very broad) language interests, Lingvo satisfies most of the dictionary needs I have.
Unlike the crappy internal iOS dictionary, Lingvo gives you the option of both monolingual,
and translation dictionaries. And all of them work offline -- no Internet access is necessary. Even better: you can have both dictionaries displayed at the same time.
That is, you get an English word explained in English, and then also translated to a language of your choice, right below that.
Many dictionaries inside Lingvo are free-of-charge, while other, more advanced dictionaries from top-of-the-line publishers (like Collins), can be purchased additionally. Those
advanced dictionaries tend to be very expensive (meaning up to a couple of dozen dollars), but you get what you pay for: top dictionary quality. None of the iOS dictionary crap where you can't even search within the dictionary, all the hyperlinks between various entries are dead, and you can't define words used in the definitions themselves. None of that crap in Lingvo -- dictionaries in Lingvo work just like they are supposed to work.
So, all you need to do is enable the
Lingvo button in Marvin as one of your custom menu buttons, by entering the following as your command text:
Code:
abbyy.lingvo://{define}
This line is available as a preset in Marvin, so you
don't need to type this manually! Just tap the Lingvo preset in Marvin when setting up your custom menu button, and that's it.
PS: Besides Lingvo, I also enjoy using the Larousse app as my French-to-French dictionary.
