Dictionary good; program fair

This dictionary may not serve the needs of either Portuguese speakers or of English speakers as well as they might wish. Most importantly, since both languages have complicated orthographic and pronunciation systems, the lack of an IPA representation of the phonemes is a significant weakness. There are recorded sounds instead, but the quality is so poor that I had trouble understanding the performance of several common English words. In addition, if the environment is noisy, as it might be out on the street, you’re not going to hear these at all.

The history mechanism is very clunky. There’s no way to just use a keystroke or a button to go backward and forward in the history; you have to change to history mode to see the list. In addition, if you go back and forth between several nodes, each visit becomes a new entry in the history list, so the utility of the list gets smaller and smaller.

I am glad to see another good English-Portuguese dictionary available in the App Store. I have been using the Collins bilingual released by Ultralingua. The Portuguese content is stronger in this dictionary, I think, but that program is easier to use. You might want to look at both of them.

Melhor do que um dicionário de bolso

Extremely useful and easy to use. I carry around a pocket dictionary in my backpack (Larousse), but this proved to be far more useful and accurate. While it isn't a dictionary for slang or idioms, it does include a great deal of expressions whose meanings I have never been able to comprehend (until now...such as the infamous "macacos me mordam" expression). The dictionary also includes useful charts for "curiosities," which include things like animal groupings (i.e., a school of fish, a gaggle of geese, etc.), mathematics, and even animal voices (buzz, roar, quack, etc.).

The dictionary itself is outstanding, and the app only adds more functionality (and at an outstanding price, especially when compared with the price to own the hard copy of these dictionaries!). Switching between Portuguese, Portuguese/English (translations into English), and English/Portuguese (translations into Portuguese) is as simple as touching the button with the flags to cycle through the languages. I found that searching for a word is much easier and quicker with the app as opposed to an actual dictionary.

Well worth the price

So many beautiful words! Definitions, usage suggestions, conjugations, cross referencing, slang. Useful resource for writing and translation.
