Picture yourself in this scenario. You are having lunch in an unfamiliar part of town and a good friend turns pale and quiet. He thinks he is having a heart attack. The nearest hospital you can think of is several traffic jams away. What do you do?

You pull out your smartphone, open the Patronus Stalker App, hit the emergency Medic button and instantly get a Google-based map of the nearest medical centres.

When you get down there and you can’t find the emergency entrance, you use it again to quickly dial their number and get directions.

It’s not often we get to use a product we built for someone else to such life saving effect but Matthew is very, very glad he had it on his iPhone that day!
