Getting found when lost

There are many apps out there that claim that their app will find you if you get lost, but how accurate are they really? I have used many apps in my time as probably you have too, with very mixed results.

People say you can use your postcode but that only gives you an area and doesn’t really tell people exactly where you are though does it, you can use map apps but again very few will give you an exact location, but the smartphone app what 3 words certainly does that and getting found when lost becomes much easier.
