Excellent, easy to use, has many colloquial terms used throughout Latinamerica.

I used to have this dictionary in my old Treo, and missed it a lot. Glad to see it on the iPhone platform. Performs flawlessly, speciallly when you are struggling to find the right word. You know it one one language but not in the other. Solid app.
