Although the number of people who speak the English language is constantly growing, it is never going to be completely universal. As such, when you are travelling to a foreign country, it is useful to take precautions to allow local people to understand you and vice versa. In the past, the communication barrier was eliminated using grammar and vocabulary books, or relying on a friend who spoke the language. However, with the technological explosion in the modern era, the world has become smaller, and along with it communication has become easier and more mobile. In particular, smartphones can now download translation apps, many of them offered free of charge. The question is, are these apps as useful as they claim?

Firstly, it is important to establish why, when travelling, one should opt for a free app rather than a paid one. The simplest response to this query is that with so many free applications out there, why pay for one! Additionally, the everyday person travels for short intervals, approximately a week or two, and as such, does not require long time use of translation applications. In the case of a person relocating to a region where they do not know the language, a translation app will not suffice.
