also has a desktop/web version aarddict.org/ I like it.

This is not the reason why I'm using it in the first place, but one of the main benefits of using an offline dictionary is that it's blazingly fast.

It turns out is the app I've always been looking for: a dictionary app to which source dictionaries can be added. When looking up words, it does so in all your dictionaries. For example, when looking up a word in a target language, it might find it in a "native to target" language dictionary, as well as in a target language dictionary. Or in just one of them. The inferface is not so pretty but very functional.
