Today I got a panic-stricken phone call from better half on a borrowed phone... she'd lost her handbag, containing mobile, purse, credit cards etc. Last she remembered was putting it down on a garden wall in the next town, two hours earlier, when she was picking up a relative.
Thankfully we allow tracking of one another, using iOS 'find my friends', I'm sure Android will have an equivalent. I asked Siri, 'Where is ....', and moments later confirmed the iPhone at least, was still exactly where she'd left it.
By the time I'd raced around there in the car, stopped outside the house... no handbag.
Find My Friends still insisted it was nearby, but zoomed on the map it had moved to the other end of the drive. Sure enough, on closer inspection, some passing Good Samaritan had moved it out of sight, to outside the back door of the house.
I'm normally wary of privacy issues with location tracking Apps but have to admit, this time it came in darned useful.
