Do you know where you are?

Today we were the first to arrive at a road traffic accident. We only had a vague idea of our location as did the 4 people in the car behind. The emergency operator kept pushing us for our actual location, then I remembered my husband, who was down the hill directing traffic, had the What3Words app on his phone. Ambulance arrived within minutes. After statements were taken the police and ambulance told us that they were able to find us so quickly because of What3Words.
Please, I urge you to download this app. I don’t download anything onto my phone but it was the first thing I did when we got home. My husband has had it for ages but was a bit sceptical about its usefulness, it could have saved someone’s life today.
