For those of you who might be using a Mac, I found this very useful plug in:
http://lipflip.org/articles/dictcc-dictionary-plugin

You can add the great (and free) dict.cc dictionary to the Mac's dictionary app, and then you can right click on any word in any window to look it up. It works great!

Thanks for this website by the way, it is great for practicing:

Does anyone have any recommendations for a good iPhone German dictionary? I've tried looking, but there are so many it's quite confusing. Some even appear to be the same dictionary in different apps, and you can never tell until you buy it. I'd be willing to pay the price for a good one. So far, I use the dict.cc iPhone app, and it's very good considering that it's free, but it's lacking a few things I'd like, such as the gender. You only see the gender of a German word when looking up the translation for an English word. It will show the equivalent German word or words with gender in that case. However, if I look up a German word, it shows me the meaning in English but doesn't tell me the gender.
