In case you got lost in a city or out on the trip, hiking, mountain climbing, etc., you can get your GPS location and transfer it to a selected phone number via SMS. An automatically generated link is created and added to SMS, showing your position on Google maps, and allowing your parents, friends, etc. to find you and help you out. Suitable for children, who might get lost, and an aid for parents to find them quickly. Can also serve as a position report.
Very bad app. Don't bother.
