Tangerine app for iPhone and iPad
Tangerine is an easy to use German-Chinese dictionary.
It comes with a database of several thousand words which can be searched for in both directions, from German to Chinese or from Chinese to German. Chinese words can be entered in pinyin notation or using the Chinese keyboard layout. Both traditional and simplified characters are supported.
The Chinese dictionary lookup uses the free CEDICT dictionary from http://cc-cedict.org/.
