Firefox OS app for an English-German dictionary, see https://schnark.github.io/install.html?id=deng for more information.
Note that this repository is managed as described in https://xkcd.com/1597/.
This app is based on ding by Frank Richter, see https://www-user.tu-chemnitz.de/~fri/ding/
The dictionary is just a copy, and the design is much inspired, but otherwise this app is completely independent from the original.
To avoid confusion this app is called deng, which also expresses the fact that (at least currently) it only works for German and English.
