Unbelievably useful, especially the conjugations!

First, it contains clear examples of pretty much every expression, figure of speech, and the dozens of different uses for words with multiple meanings. Second, it has every conjugation of every tense of every verb... I dont know what Id do without that. The conjugations are much easier to access in the iPad version, but with a couple extra taps you can get there on the phone as well. Also, it is truly bi-directional: The entries are equally as detailed whether going from English to Spanish or Spanish to English.
