Lingua.ly is a site that allows you to build up your reading skills and vocabulary in a language of your choice (there are 17 languages to choose from, English included). You can use the desktop version of Lingua.ly or its app.
To start using Lingua.ly, first you have to log in through your Facebook account or through your Google account, then you choose the language you want to study and your level (beginner, intermediate or advanced) and off you go.
You are given a selection of articles from the international press and once you have made your choice, you start reading it. You can build up your own personalised dictionary by selecting individual words that you want to learn. Lingua.ly will store them for you and will show you how to pronounce them. You can use these words for revision purposes later on.
