Why has this not been thought of before? It’s so simple it’s laughable

Why struggle to remember the address of where you are going, especially when it’s Postcode covers several buildings that don’t have a number on.

Have you ever had to look for an address that you discover doesn’t have its number on & can’t be seen from outside? I have pulled my hair out at times when trying to find “the cottage” or “XYZ Limited’s” building that doesn’t have its name on? What3Words has been the answer to my prayers!

Same goes for going on holiday where “Sol Mare”, last September I went on holiday to Greece, the coach couldn’t get to the hotel directly due to it being half a mile up a track. So we were dropped off on the main road. Walking up the track on each side we found dozens of places, none of which we could read the Greek name. Fortunately the owner had given the What3Word address. This led us straight to the front door, yet several other travellers on our coach were still looking for their place by the time we were sitting on our balcony.

What3Word is my Company’s addressing system now. We have cut out days of lost time since September 2018- March 2019 in lost man-hours looking for customers addresses.

It even works in my Mercedes too. Just put in the three word address and the car’s Satnav delivers me to the door.

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!

To counter the “pointless” reviewer

Writing a review to point out the mistakes in the reviewer who titled their review “Pointless”. At first I assumed that it required data signal to interpret any GPS location into a 3word location. The fact is, once downloaded to try, is that in airplane mode the app can still leverage the iPhone’s built in GPS module to get a location. Furthermore, you can pinpoint ANY location in the world, and find the 3word location. This is impressive: means that it somehow has a full mapping of EVERY 3x3 square in the world, available to identify where you are.
Of course, the issue then is how you’re supposed to contact someone if you don’t have any digital network signal... but in general, say you’re lost in a city and need to find the one and only open gate to a location, you can specify and share to your friends (who also have this app).
