Heads-up to a really clever app for sharing gps locations to the nearest 3m, without using Lat Long.  

Emergency services in my neck of the woods have started using it.

And great for RVing with people/family at precise, rather than vague, locations:

Just tried it, really good.  Thanks for the tip

Yep , so it has it's uses so long as everyone has a suitable digital device, completely useless if they only have charts.

Well, yes, but rather a negative take. How are you visualising the UK communication between caller and recipient taking place? No mobile phones. VHF/ phonebox only?  Individuals without gps, but carrying relevant maps or charts?  That sounds like a scenario from the era of Heartbeat😂😊 

For UK use, ithe what3words comparator is against the inaccuracy of gps postcodes: Imagine you're calling an ambulance (presumably, from a phonebox, because your scenario doesn't envisage havinh a mobile phone) to someone in a large car park - what3words will get them within 3 metres. Postcode or address, if you know it, would just get them to the general area, and then you'd have to try to talk them in...from the phonebox.   

Lat Long? Good luck with finding your Lat Long in that car park, to similar accuracy, without a gps: Carrying an air nav chart when you go shopping, being able to determine your Lat Long from that chart, and then passing that Lat Long on a 999 call (again, from a phonebox, because you don't have a mobile phone) and it being understood and useable by a recipient also without a gps but, happily, with a chart covering where you happen to be.  (Think a helo could prob deal with it (albeit, almost certainly with dig lat long into a gps, rather than charts) but anyone else: no chart, no understanding of lat long, blank face) 

Same goes for grid ref without gps: You'd have to be out shopping carrying the correct map sheet in the car park (does anyone?!) and be able to map read precisely to 8fig anywhere; and then pass the grid by phone (again, from a phonebox, because you don't have a mobile phone) to someone else who not only has the same sheet, but can also map read to 8 fig - I doubt most emergency vehs carry full 1:50,000 OS mappage for their whole area, or, other than mtn rescue, have many (any?) responders trained in reading such maps to 8fig.

Or.. less dramatic... you're meeting a pal's picnic group at a massive outdoor concert ...what3words gets you within 3m in the open space covered by crowds of people

I can only see postives, and nothing to be reflexively cynical about. 😊

What3words is accurate to 10 feet.

Modern L5 band GPS is accurate to 8" - 12"

I wonder if the military will use it to call in air-strikes 😉

It wouldn't be too shabby for that, using google earth photo view it, essentially, gives a point mensurated target location. ...  and 3m x 3m box  isn't 3m accuracy, it probably represents a CEP of about 1.7m  ....plenty close enough for government work.
