There are millions of different locations alongside lots of different words that can be used to describe a location. For example, "King's Cross Station" is three words that describe a location but in turn provides a very specific location - pinpointing one train station out of hundreds in London. However, King's Cross Station itself is 75,000-square-foot and has a wide array of different exits as well as having twelve different platforms. Regardless, there may be certain landmarks and phrases that make your exact location easy to identify such as "I'm directly opposite from The Harry Potter Shop at Platform 9 3/4". However, other locations aren't as easy to recognise especially if the location is unfamiliar.
What3Words is an app that's been created that people can use in 143 countries to pinpoint their exact location, wherever they are. It's been praised for being something in which could save someone's life if they were unsure where they were, such as when camping, hiking or someplace that they'd never been to before. The premise of What3Words is that 3m squares are used and given a unique combination of three words - such as square.triangle.hill or limit.broom.flip. It's available in 37 languages and the app also works offline, which means that people can use the app confidently, and plan their trips abroad more efficiently,
Other than using it in an emergency, many people use What3Words to document and remember locations that they've visited that they otherwise couldn't remember. These spots can be categorised further by using the list function provided directly in the app. The same principle applies when sharing images to friends or family, where the three word sticker can be added so it can easily be recognised and correlated to a location.
