Extremely helpful for simple EN-DE word lookup and back. Great that you have switch from one language to another in a language pair by just double-clicking a word of interest. Unfortunately, it misses etymology just as its online version, but it's what you expect. I am looking forward to see apps for other language pairs because there are plenty of them available online. It would be extremely interesting to see an app with Latin and Spanish languages. Good app!

just ok，the ui is not beautiful～
