Things that happen all the time:

1

You're buried deep in your work, and you cannot find your phone.

2

You hurry out of the store, and you do not know where you put your phone.

3

You put your phone down in the taxi, and you forget where you left it.

4

You bump into a stranger, and your phone is gone.

This list of things goes on and on, and you wish you had an alarm that would sound when your phone is not in a safe range around you.


As simple as a caveman and his rope.

An alarm that can be used to protect all of your valuables!
