This is a Portuguese dictionary that has several advantages:

The dictionary is completely installed onto your Android phone or tablet. Therefore, you do not need Internet access to search and read the definitions. This is ideal for use in class and / or room in any situation, especially when there is no network access.

The dictionary allows you to turn reading aloud and when you press a definition, Android will read aloud what that word meant. (You need to be activated before speech synthesizer in Portuguese, in Settings / Language on your Android)

Clicking on a definition, it is copied to the clipboard. You can paste it in any other application that deals with text, for example, in an SMS to WhatsApp or Facebook entry.

In exchange, because the dictionary resides on your Android, occupy much space (minimum). The application occupies 10 megabytes to install and when installed it increases slightly. It is the price and weight of knowledge :)

This dictionary is not only limited to words in Portuguese language: Inlcuye also plenty of words in other languages. I mean that is more complete than a conventional dictionary: It's practically a multilingual dictionary!

In all cases, the description of the term is in Portuguese.
