Why might I need the what3words app in an emergency?

​Emergencies can happen anywhere, at any time day or night and often in unfamiliar places. This can make describing your location very difficult if you need to call 999. Having a precise location can help emergency services find you much faster, and what3words is a way for you to describe your location, accurate to 3x3m square, using just 3 words. These 3 words can then be shared with and used by emergency services, to find you easily.
