I work in Brasil & have been using this dictionary for over a year now & found it to be indispensable before the update.
I was a bit jarred by the completely new user interface & then I clicked on a verb to conjugate & found that the developers have added an extremely important element for verb conjugation which is missing in EVERY single book (including 501 Portuguese verbs.)
This dictionary now includes Portuguese & English conjugations side by side for most of the verb forms in the dictionary!
Now you dont need to know the meaning of preterit, mais que perfeto, subjunctivo, etc.
This makes your learning experience a ton easier!
Compared to most iPhone/iPad apps this app is expensive; but if you need to learn Brasilian Portuguese, dont be a cheapskate & cough up the dough!!!
You only pay once & you can use it on both the iPhone & iPad...
