Good solid dictionary

As with Steam Heavys Wörterbuch, this is based on the Wiktionary definitions, but this one wont crash in iOS 5. Its a great source for conjugation information, and contains many words that you wont find in most other dictionaries. On the downside, it requires a WiFi connection to work. Definitely worth the download in spite of this occasional inconvenience.
