Spartacus Red ,


It is hard to believe that it so accurately captures the essence of the original. I have both the English and Russian copies of the article so I can compare the translation with the original English. It is amazingly accurate. What a difference in these free translation programs from paid ones of 10 years ago. A grateful “Thank you”.

Developer Response ,

Thank you so much for your high review! We appreciate it!

I use this app for Clash of Clans only

German <-------> English only. I am in a German clan who doesn't speak English. I use English ---> German most of the time. If I use very, very simple sentences like "Who wants Archers?" It's okay. Or, "Who needs Archers?". More complex sentences with more complicated syntax, like "Who wants a level 2 siege machine donation for clan war?" not so well. Oftentimes my clan members have no idea what I'm trying to say.

The app is, however, very good at translating single words. The "library" utility is excellent. Especially when you store often used phrases in the "favorites" folder. I would buy this app again, but I will most likely look for a different app with fewer translated languages. I think overall translation quality may suffer a bit with so many different languages to maintain.

Accurate translator

As I am learning German language, I happen to personally evaluate different translators in terms of accuracy and user interface. I can surely say that this one ( powered by PROMT) comes really handy. I can be compare with Google translate and in some context this perform fast more better that Google translate. Thank you developers for making this app free.
