What3word App is a light in the darkness to guide

It is accurate to 12 feet after each calibration. But it's utility is poor as the other recipient also should have your App to enable interaction of What3 words App. I search an address but I cannot communicate to the individual who own the address via your App. I have to use WhatsApp or email to communicate the What3word address. So enable the profile suitably.

What3words Great app solved my delivery problems.

Having been unable to get on line deliveries because couriers struggled to find my property even with explicit directions years of having to have parcels sent to family miles away. Using what3words has for the first time used, enabled courier to find and deliver I'm so grateful to have solved this problem.

Brilliant company!

Brilliant company!! Simple effective app, that has saved so much time in my wife and my own work, as well as deliveries drivers actually being able to find us now. A+++

I can't believe that What Three Words…

I can't believe that What Three Words can provide code words for every 5m square location throughout the whole world, using only three words! Of course, I have only tried it thus far in the UK, but having a readable map (Google Maps) I can point to a specific square and read out the three words provided by What Three Words.

Fantastic for finding remote address

Fantastic for finding remote address, meeting friends at places like beaches and countryside. Our granddaughter was lost in a city and didn't know how to explain where she was. She then used What3words and her mum went straight there. Amazing tool. I go on long hikes and bike rides, and have the security of knowing if there is an emergency while I'm out, I can sent my What3words location

So Easy

I did not think it possible. I just keyed in the address to my What3Words and it gave me the lat-long address which Google maps then sorted out a route for me. So easy!

Easy and free to use

I’ve found what3words to be incredibly helpful. Last month I used it to direct the firefighters to a fire at a scrap yard. I didn’t know the name or address. I gave 999 the what3words address and they located it immediately. I usually use it for deliveries, for meeting friends at rounders practice on large and busy fields, and when traveling abroad. It’s quick and the app is free. Definitely recommend it.

This is literally a life saviour

This is literally a life saviour. My son had a serious motorbike accident while on green lanes in the middle of nowhere. He called 999 and the ambulance team sent him a link to what3words. They managed to find him straight away in a field off the road. He had serious injuries and was immediately taken to hospital. I don’t know what would have happened had he not been able to use this incredible device. I am truly so grateful to What3words. On a less serious note I live in a village where 14 properties have the same postcode. I use What3words on a regular basis for deliveries or friends visiting. I could not live without it now. Thank you 🙏

I think what3words is ingenious

I think what3words is ingenious. It’s very helpful for someone who is not great at the basic level of directions. The idea that emergency services can locate those off road is amazing. I even used on my wedding invite!!

One of the best apps out there

Use it all the time to meet up with work colleagues or friends as it gives a pin point location instead of having to use road/building names or descriptions which can be misinterpreted.

The future

Excellent App. I’ve used it quite a few times to describe a location. It’s the future of addresses.

This app's a Life Saver!

Since I discovered this app it's been a life-saver: literally! I live in the Lake District, and one of the first times I used it was to call in Mountain Rescue to a walker who'd fallen 50 feet down a ravine and dislocated his shoulder. It's way better than a postcode: my son lives down a rural road where the postcode takes you down a parallel (but wrong) road: using What3Words lands delivery drivers at his gate. It's an app I recommend to so many people as it's just so accurate and, in many cases, the ONLY way of getting to exactly where you need to be!
