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.

Used last Friday, Scotland, UK

Im an ex military, para with a medic specialty. Used to work for 999 Emergency when retired. The most important thing for us was always to establish precise location. Last Friday i was running down very steep hill with an intention to speedfly. Unfortunately my foot got stucked in between the rocks while i was still running in result it was twisted and almost fully torn off. Still concious i have managed to disconnect of harness, pack it and crawl down to the small space emergency servises could easily approach. When i say easily that means i was on relatively flat ground not a slope. This is when I called Emergency Services and used my app. Without it i would not be able to say anything except North Slope which is many miles long. Multi agencies including Air Medivac were involved and help arrived promptly.

Brilliant idea, app needs some work

Brilliant idea but the app needs basic features adding. There is no search history which is a nuisance. As an example I’m running a training course at a customer site and I need to travel to and from the hotel I’m staying in every day for a week. Because there’s no search history I need to type in the customer’s name every morning and the hotel name every evening, bit of a pain, especially as I can’t remember the name of the hotel, so I have to search my emails for the booking confirmation... In both Waze and Google maps the last twenty or so addresses appear below the search box.

Ok, so I could favourite each location the first time I visit, favouriting is easy, can be done with one tap, apart from adding the label! But I have remember to do that... ugh.

But then accessing a favourite needs four taps, one to save, four to get to! No quick access to your favourites from the search bar either. Even worse, the search doesn’t look in the favourites! I’ve labelled my home address as Home but searching for Home doesn’t find the favourite. When I have a hundred or so favourites how do I search them?

I love the idea and there are situations where this app has no equal but without these basic features Waze and Google Maps are still more convenient to use.

Please add these features.
