This dictionary Spanish has several benefits, I tell you:

Dictionary installation on your Android and does not need the Internet to display definitions. This is ideal for use in class and / or any situation, particularly when there is no network access.

The dictionary allows you to turn reading aloud and when you press on a definition, your Android will read aloud the meaning of that word.

By clicking on a definition, it is copied to your clipboard so you can paste it into any application that handles text, for example, in an SMS, the inlet Whatsapp or Facebook.

In return, because the dictionary resides on your Android, occupies much space (bare minimum). The application occupies 22 megabytes to install and when installed this increases to 100 megabytes. It is the price and weight of knowledge :)

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

In all cases, the description of the term is in Spanish, and the dictionary says that you come from original language that exposes each term.
