AddDict

AddDict is a helper application that downloads and installs offline electronic dictionaries for the so-called dictionary shells such as ColorDict and GoldenDict.
The app runs on both phones and tablets with Android ver.2.3.6 or greater.
GoldenDict is much more versatile than ColorDict but either of them understands the DICT-formatted files that AddDict can fetch to your Android gadget.
In fact, any application that is familiar with DICT format should be able to work with them smoothly.
In principle, you can even transfer the downloaded files to your desktop/laptop and then use them with free software such as cURL, Fantasdic, StarDict, etc.
on PC, GNOME Dictionary on Linux, OmniDictionary on Mac OS X or SilverDict on Windows Phone, to name just a few.
AddDict's user interface is intuitive and self-explanatory while installation process does not require any special interference such as converting files, renaming or moving folders, etc.
Both ColorDict and GoldenDict in their default configuration will recognize and index the downloaded files fully automatically thus providing the user with instant access to their new dictionaries.
As of June 9, 2015, there are 68 dictionaries in 14 languages (over 5 mln.entries) that can be downloaded with AddDict ver.1.2.
