Buensoft Ingles is a simple and free application for Windows with which you'll enjoy learning English the easy way.
The software works by using subjects, each one designed for you to learn different areas of the English language.
The learning mode works by levels, so some activities are blocked until you have reached the required level in the subjects already available.
All of this makes Buensoft Ingles an application that is worth giving a try.
This free version includes five subjects; five more subjects can be obtained by subscribing to the basic version for free.
