Good all-around heavyweight dictionary

This dictionary works great and is a good subtitute for the large paperback Websters that I use for German language classes. However, it is missing 3 things in my opinion:

1. A list of irregular verbs with infinitive, present indicative, imperfect past, and perfect past forms.

2. Better derivation of the infinitive from any conjugated form of the verb. The Accio app is much better in this respect.

3. A thesaurus would be a nice feature for common words, if not all words (esp. adjectives and adverbs)

The app can be a bit slow to load an entry (my phone is a 3G, YMMV) and will display the last word you looked up for a second until it updates.

Overall the app is a good value, but not much more comprehensive than Accio which is 1/10th the price.
