localisator is an app that allows its users to share their approximate location with their loved one, if they also use the app. All you need is your loved one's phone number to appear in the app and you can communicate your locations.
As a feature, we see:
Location request (if you are a blocked contact)
Location mailing
Location sharing with all your contacts (which you can turn on and off at any time)

The aim is to forget the famous question: "Where are you?" in a world in full technological development like ours.
