Addressing made simple!

What3words is a fantastic way to discuss location. There’s no need for complicated descriptions, erroneous addresses or lengthy coordinates. Simply open the app, press the locator arrow, and BOOM! Your local 3m x 3m grid square is addressed 😎👍 Perfect for tagging your car in a car park, letting family and friends know where *exactly* to meet at an event, or simply to let people know where you are in the countryside.

This breakthrough new way of discussing location is making waves across society, both in industry and emergency services, so the more we use it the quicker everyone will adopt it. It’s great, it’s free, and it’s so useful!

For shoppers or site-seers, I’d highly recommend the partner “3WordPhoto” app, as you can snap your newfound bargain or favourite vista, and instantly be able to locate it again in future!

Fun but also extremely practical

I found out about this app after a friend of mine on a neighbouring farm had a stroke and despite being told not to follow the postcode the emergency services did so and arrived at the wrong farm. My friend found out about this app and felt medical help could have been given much quicker if the 3 word location had been used. However I am not sure if the emergency services have this yet in the UK so my interest was more out of curiosity than anything. It is a joy, just as a linguistic play. The randomness and spookily appropriate nature of the words generated is a joy. I recommend this to anyone who has a love of language.

Brilliant Idea

This is really, really clever and a great boon if one is trying to describe a precise location to a distant co-worker or delivery driver. The most recent update now enables one to save locations with a brief description, and delete old searches, which was not possible before. The location saving process is a bit fiddly, but it works, I am sure refinements will be coming in the future, it would be good to be able to group locations in folders etc.

Developer Response ,

Thanks for your support and feedback - with our latest update you can now clear your recent searches and save locations to your account. Hope you continue to enjoy using the app!
